RIDGE VENT
Overview
Quarrix Ridge Vent is the most versatile attic ventilation product on the market. It works with all roofing
materials and installs on the hip and ridge for a clean appearance. Quarrix Ridge Vent helps keep attics cool
and allows hot, moist air to release at the highest point, which is essential to achieving a balanced ventilation
system. The StormStop® Membrane allows air to flow while preventing all forms of weather from entering the
attic space. Quarrix Ridge Vent is available in 20’ Rolls and 4’ Sections.

BALANCED SYSTEM - THE KEY
Attics need to breathe in to breathe out. Simply exhausting
air isn’t enough. There needs to be enough air that comes in
at the eave of the roof to create a balanced system.
Creating a balanced system is easy with intake and
exhaust vents in 20’ rolls or 4’ sections - hip exhaust, ridge
exhaust and roof deck intake.
Asphalt shingles, wood, steel or tile – Ridge Vent
installs with all types of roofing materials. Breathe easy with

Using ridge vents is always the
best option for exhaust, however
homes with large center beams
are not compatible with their
design. Multi-Use Vent can
be installed just off the peak
on both sides of the ridge
to provide the same needed
exhaust.
Eave Intake Shed Wall ExhaustOff-Peak Exhaust
Many homes have roof-to-
wall situations that are usually
ignored. This can create hot
spots in the attic. Multi-Use Vent
allows those areas to be vented
properly, ensuring a cool attic and
a balanced system.
THREE USES - ONE PRODUCT
For a balanced system to work,
every attic needs air intake;
however, not every home is
equipped with soffit vents.
Multi-Use Vent can be installed
as an intake vent for homes
with no overhang, too much
overhang or tile roofs.

SOFFIT VENT
Overview
Quarrix Soffit Vent provides even and continuous air intake at the eave. Traditional soffits vents segment
your intake and create “zonal” ventilation. Having continuous air flow along your entire soffit will go a long
way to creating a needed balanced ventilation system.

RIDGE VENTInstallation Instructions
Spanish
French
The amount of ventilation is controlled by the
length of slot cut along the roof ridge. For the
most attractive roofline, it is recommended that
Quarrix Ridge Vent be installed along the entire
ridge of the roof.
1. Ridge Ventilation Slot Preparation
The slot may be pre-cut on a new roof before or after
shingle installation or in a retrofit, the slot can be cut from
the pre-shingled roof using a circular saw with a carbide
tip blade (protective eye goggles should be worn during
this process). For Quarrix Ridge Vent with 5
⁄8” profile, cut
a 2” slot (1” on each side of ridge) along the ridge(s).
For a roof with a center beam, a 31
⁄2” slot should be cut
(13
⁄4” on each side of ridge). For Quarrix Ridge Vents with
1” profile, cut a 21
⁄2” slot (11
⁄4” on each side ridge). For
center beam applications a 4” slot should be cut (2” on
each side of ridge). A minimum of 6” must be left uncut
on each end of the ridge. Once the slot is cut and any
overlapping shingles covering the ridge are trimmed and
removed, the ridge is ready for vent installation.
1. Preparación
de la ranura para
el respiradero
de cumbrera La
ranura puede
cortarse en un
techo nuevo
antes o después
de la instalatión
de las tejas o en una remodelación. La ranura puede cortarse
usando una sierra circular electrica (Se debe usar lentes
protectores durante este proceso). Para los respiradores
de bajo perfil de Quarrix, corte una ranura de 2 pulgadas
(1 pulgada de cada lado de la cumbrera). Para un techo de
viga central, se puede cortar una ranura de 31
⁄2 pulgada (13
⁄4
pulgada de cada lado de la cumbrera). Para los respiraderos
de alto perfil de Quarrix, corte una ranura de 21
⁄2 pulgada
(11
⁄4 pulgada a cada lado de la cumbrera). Para un techo
de viga central se debe cortar una ranura de 4 pulgadas
(2 pulgadas en cada lado de la cumbrera). Se debe dejar
un minimo de 6 pulgadas sin cortar en cada extremo de
la cumbrera. Una vez que se ha cortado la ranura y se han
superpuesto las tejas que cubren la cumbrera, ésta estará
lista para la instalación del respiradero.
1.Préparationdelafentedeventilationdel’arêteLafentepeutêtre
pré-coupée sur un nouveau toit avant ou après l’installation
du bardeau ou lors d’une installation rétroactive, la fente
peut être coupée du toit pré-imbriqué au moyen d’une scie
circulaire avec une lame à pointe au carbure. (Des lunettes
protectrices doivent être portées durant ce processus.)
Pour les évents de faîtage Quarrix à profil de 1,6 cm, coupez
une fente de 5 cm (2,5 cm de chaque côté de l’arête) le
long de l’arête (les arêtes). Pour les toits avec une poutre
centrale, une fente de 9 cm doit être coupée (4,5 cm de
chaque côté de l’arête). Pour les évents de faîtage Quarrix
avec un profile de 2,5 cm, coupez une fente de 6,4 cm (3,2
cm de chaque côté de l’arête). Pour les applications avec
une poutre centrale, une fente de 10,2 cm doit être coupée
(5,1 cm de chaque côté de l’arête). Une distance minimale
de 15 cm ne doit pas être coupée à chaque extrémité de
l’arête. Une fois la fente coupée et tous les bardeaux se
chevauchant couvrant l’arête émargés et enlevés, l’arête
est prête à l’installation de l’évent.consequat.
2. End Cap Installation
Pull apart a pre-cut
section of the foam end
cap found with the vent.
Using a utility knife, make
a cut in the StormStop®
material 1
⁄2” on each
side, back from the end
of the section. Using
construction adhesive or
sealant caulk, coat both
sides of the StormStop
material where it has been
cut back at the end of
the vent. Insert the foam
end cap with the cut-
back StormStop material
between the foam end cap
and the underside of the
vent to assure a weather-
tight seal. Sealant must
be applied to roof shingles
before installing vent.
See Step 3 for approved
sealants.
INSTALLATION

2. Instalación de los tapones ciegos Separe una sección de
los tapones ciegos de esponja cortada previamente que
viene en el respiradero. Con una navaja haga un corte de 1
⁄2
pulgada en la membrana StormStop a cada lado, desde la
parte trasera del extremo de la sección. Con un adhesivo
o pegamento para construcción, pegar ambos lados de la
membrana StormStop donde se cortó. Coloque el tapón
ciego de esponja en la membrana StormStop en la parte
inferior del respiradero y asegurese que esté correctamente
sellado. Ver paso # 3 para sellado apropiado.
2. Installation du capuchon d’extrémité Séparez une section
prédécoupée du capuchon d’extrémité en mousse se
trouvant dans l’évent. Au moyen d’un couteau universel,
effectuez une coupe dans le matériau StormStop® de
1,3 cm de chaque côté, à l’arrière de l’extrémité de la
section. Au moyen d’un adhésif de construction ou d’un
produit de scellement, enduisez les deux côtés du matériau
StormStop à l’endroit où il a été coupé à l’extrémité de
l’évent. Insérez le capuchon d’extrémité en mousse avec le
matériau StormStop coupé entre le capuchon d’extrémité
en mousse et la partie inférieure de l’évent pour assurer
une étanchéité imperméable. Le produit de scellement doit
être appliqué aux bardeaux de toit avant d’installer l’évent.
Reportez-vous à l’étape 3 pour connaître les produits de
scellement approuvés.
3. Vent Placement on Ridge
Attach vent to the roof deck by driving a nail in each of
the two corners on both ends of the vent. Also, drive two
nails through the vent and foam end cap to hold foam in
place on the ends of the ridge only. Nails should penetrate
the wood roof deck at least 3
⁄4”. It is not recommended
to nail vent to ridge prior to cap shingle installation.
Because of the popularity of
dimensional roofing material
such as the newer 40/50
year and lifetime laminated
shingles, we require that a
bead of sealant be applied
to the roof shingles before
installing the vent on the
ridge. This sealant should
fill any voids between
the bottom of the vent
and the surface of the
shingle. Use either butyl
sealant conforming to
ASTM C1085, latex sealant
conforming to ASTM C834,
silicone sealant complying
with ASTM C920 or asphalt
roofing cement complying
with ASTM D4586. Roll
out or place Quarrix Ridge
Vent along the entire length of slot also covering the
6” minimum uncut ridge on both ends. Bend vent into
a “V” Shape. Secure at the lead edge after inserting
the end cap. Nail should penetrate roof deck a minimum
of 3
⁄4”. Pull the vent tight and secure at about 10’. Pull
the rest of the vent tight and secure, inserting the end
cap. Multiple lengths of vent can be joined by butting the
sections tightly together. End caps should be inserted at
the beginning and end of each section. Do not pre-fasten
ridge vent along the entire vent; with Quarrix Ridge Vent’s
One-Pass™ Installation, it is not necessary to pre-fasten
the vent every 2’ to 3’ prior to cap shingle installation.
3. Aplicación del respiradero en la cumbrera Colocar el
respiradero en la cumbrera del techo y clavar dos clavos
en cada esquina del respiradero. Tambien clavar dos
clavos cerca de los tapones ciegos de esponja. Los clavos
deben penetrar en el techo de madera por los menos 3
⁄4
de pulgada. No se recomienda clavar el respiradero en
la cumbrera antes que las tejas. Debido a la cantidad de
materiales para techar en las nuevas tejas laminadas de
40/50 años de duracion requerimos que se aplique un
sellador en las tejas antes de instalar el respiradero en la
cumbrera. Este sellador debe llenar cualquier vacio entre la
parte inferior del respiradero y la superficie de la teja. Use
un sellador de butilo que cumpla con las especificaciones
ASTM C1085, un sellador de latex que cumpla con las
especificaciones ASTM C834, un sellador de silicona que
cumpla con las especificaciones ASTM C920 o un cemento
para techar de asfalto que cumpla con las especificaciones
ASTM D4586. Aplique el respiradero Quarrix a lo largo de
toda la longitud de la ranura incluyendo las 6 pulgadas que
no fueron cortadas en ambos extremos. Doble ligeramente
en respiradero en forma de “V”. Asegure los extremos
colocando un tapon ciego de esponja. Los clavos deben
penetrar el techo un minimo de 3
⁄4 pulgada. Extienda
el respiradero y asegurelo aproximadamente a 10 pies
colocando un tapon ciego de esponja en cada extremo.
Multiples porciones de respiradero pueden juntarse
empalmando las secciones bien apretadas. Los tapones
ciegos de esponjas deben colocarse al principio y al final
de cada sección. Con Quarrix One-Pass Installation no se
recomienda pre clavar el respiradero cada 2 o 3 pies, no es
necesario antes de instalar las tejas.
3. Placement de l’évent sur l’arête Fixez l’évent au platelage en
enfonçant un clou dans chacun des deux coins aux deux
extrémités de l’évent. Enfoncez aussi deux clous à travers
l’évent et le capuchon d’extrémité en mousse pour tenir la
mousse en place sur les extrémités de l’arête seulement.
Les clous doivent pénétrer le platelage en bois d’au moins
1,9 cm. Il n’est pas recommandé de clouer l’évent sur
l’arête avant d’installer le bardeau du capuchon. À cause
de la popularité du matériau de couverture dimensionnel
comme les bardeaux laminés avec garantie de 40/50 ans et
à vie, nous exigeons qu’un boudin de produit de scellement
soit appliqué aux bardeaux de toit avant d’installer l’évent
sur l’arête. Le produit de scellement soit appliqué aux
bardeaux de toit avant d’installer l’évent sur l’arête. Le
produit de scellement doit remplir tous les vides entre
la partie inférieure de l’évent et la surface du bardeau.
Utilisez soit un produit de scellement en caoutchouc de
butyle conforme à ASTM C1085, un produit de scellement
au latex conforme à ASTM C834, un produit de scellement
à base de silicone conforme à ASTM C920 ou un ciment
de couverture bitumé conforme à ASTM D4586. Déroulez

1,9 cm. Tirez l’évent fermement et fixez-le à une distance
d’environ 3 mètres. Tirez le reste de l’évent fermement
et fixez en insérant le capuchon d’extrémité. Plusieurs
longueurs d’évent peuvent être reliées en emboutant
les sections fermement ensemble. Insérez un capuchon
d’extrémité au début et à la fin de chaque rouleau. Ne fixez
pas préalablement l’évent de faîtage sur toute la longueur
de l’évent; avec l’installation One-Pass™ de l’évent de
faîtage Quarrix, il n’est pas nécessaire de préalablement
fixer l’évent tous les 60 à 90 cm avant l’installation du
bardeau du capuchon.
3b. Note: For “Class A” Installation Only
For “Class A” Quarrix Ridge Vent installation, follow
steps 1, 2, 3 as stated above. Once the vent has been
installed, use a utility knife with a hook blade and remove
the corrugated plastic
center section of
the vent. Do this
for the hip and
ridge. This modified
installation meets
the requirements
for UL790 “Class
A”; standard
installation meets
the requirements for
UL790 “Class C.”
Continue to Step 4.
3b. Solamente para la instalación de la “Clase A” Para la
instalación del respiradero Quarrix de “Clase A” siga los
pasos 1, 2 y 3 como se detalla anteriormente. Una vez
que el respiradero haya sido instalado, con una navaja de
gancho corte y remueva la sección central del plástico del
respiradero desde el principio hasta el final. Haga esto en
toda la cumbrera. Esta instalación modificada cumple con
los requisitos para la “Clase A” UL790, y cumple con los
requisitos de instalación estadar para la “Clase C” UL790.
Continue con el paso # 4.
3b. Pour les installations de « catégorie A » seulement Pour
l’installation d’évent de faîtage Quarrix de « catégorie A
», suivez les étapes 1, 2, 3 indiquées ci-dessus. Une fois
l’évent installé, utilisez un couteau universel avec une lame
à crochet et retirez la section centrale en plastique ondulé
de l’évent. Faites de même pour la croupe et l’arête. Cette
installation modifiée se conforme aux exigences UL790
de « catégorie A »; l’installation standard se conforme aux
exigences UL790 de « catégorie C ». Passez à l’étape 4.
4. Cap Shingle Installation
Using One-Pass Installation secure cap shingles and vent
at the same time. Nail ridge caps with roofing nails in a
common, overlapping pattern. Nails should penetrate the
wood roof deck at least 3
⁄4”. For the fastest installation,
a coil nail gun can be used
as long as the minimum
penetration is 3
⁄4”. It is
important when installing
this vent that you maintain
the pitch of the roof. The
vent has been installed
properly if the bottom of the
vent is flat on the roof and
the peak is slightly rounded.
4. Instalación de las tejas Con One-Pass Installation asegure
las tejas y el respiradero al mismo tiempo. Clave las tejas
en el respiradero con clavos para construcción en un estilo
de superposición. Los clavos deben introducirse al menos
3
⁄4 de pulgada en el techo de madera. Para una instalación
mas rápida se puede usar un pistola de clavos siempre y
cuando tenga una penetración de ¾ de pulgada. Cuando
se instala el respiradero es muy importante mantener la
inclinación del techo. El respiradero ha sido instalado
correctamente si la parte inferior de éste se ve plana en
el techo y el medio del respiradero está ligeramente
redondeado.
4. Installation du bardeau du capuchon Au moyen de
l’installation One-Pass, fixez les bardeaux du capuchon
et l’évent en même temps. Clouez les capuchons d’arête
avec des clous de toiture dans un motif de recouvrement
commun. Les clous doivent pénétrer le platelage en bois
d’au moins 1,9 cm. Pour l’installation la plus rapide, vous
pouvez utiliser un pistolet goujonneur à spire tant que la
pénétration minimale est de 1,3 cm. Il est important lors
de l’installation de cet évent de maintenir la pente du toit.
L’évent est correctement installé si sa partie inférieure
repose à plat sur le toit et que le sommet est légèrement
arrondi.

Determine how long of a hip and ridge ventilation slot
will be required according to 1:300 rule. The ridge and
hip ventilation slot may be pre-cut on a new roof before
or after shingle installation or in a retrofit, the slot can be
cut from the pre-shingled roof using a circular saw with a
carbide tip blade (protective eye goggles should be worn
during this process). Start ridge ventilation slot 6” from
point where hip and ridge meet. For 5
⁄8” profile vents, cut
a 2” slot (1” on each side of ridge) along the ridge(s). For
a roof with a center beam, a 31
⁄2” slot should be cut (13
⁄4”
on each side of ridge). For 1” profile vents, cut a 21
⁄2” slot
(11
⁄4” on each side of ridge). For center beam applications
a 4” slot should be cut (2” on each side of ridge). If entire
ridge requires ventilation, stop ventilation slot 6” from
point where hip and ridge meet. To maintain structural
integrity, one continuous slot is not recommended on hip
applications. Start ventilation preparation by leaving 6” of
hip uncut from where the ridge and hip meet. Cut a 31
⁄2”
wide slot for ventilation. Hip slot should be 18” in length,
spaced with a 12” uncut area between each 18” opening.
The slot for ventilation should not be cut any lower than
the top 1
⁄3 of the roof to maintain a balanced ventilation
system.
2. End Cap Installation Pull apart a pre-cut section of
the foam end cap found with the vent. Using a utility
knife, make a cut in the StormStop® material 1
⁄2” on
each side, back from the end of the section. Using
construction adhesive or sealant caulk, coat both sides
of the StormStop material where it has been cut back at
the end of the vent. Insert the foam end cap with the cut-
back StormStop material between the foam end cap and
the underside of the vent to assure a weather-tight seal.
Because of the popularity of dimensional roofing material
such as 40/50 year and lifetime laminated shingles,
we require that a bead of sealant be applied to the
roof shingles before installing the vent on the ridge.
This sealant should fill any voids between the bottom
of the vent and the surface of the shingle. Use either
butyl sealant conforming to ASTM C1085, latex sealant
conforming to ASTM C834, silicon sealant complying
with ASTM C 920 or asphalt roofing cement complying
with ASTM D4586.
Attach vent to the roof deck by driving a nail in each of the
two corners on both ends of the vent. Also, drive two nails
through the vent and foam end cap to hold foam in place
on the ends of the ridge only. Nails should penetrate the
wood roof deck at least 3
⁄4”. It is not recommended to nail
vent to ridge prior to cap shingle installation. Because
of the popularity of dimensional roofing material such
as the newer 40/50 year and lifetime laminated shingles
we require that a bead of sealant be applied to the roof
shingles, before installing the vent on the ridge. See step
2 for recommended sealants.

5. Hip and Ridge Vent Transition
Using a utility knife, trim the end of the vent from the hip
to the ridge. This creates the most attractive ridge and hip
line. Insert the foam end cap under the ridge vent where it
is at full width. Fasten vent for hip at point where it meets
ridge. Roll out or place the vent all of the way down the
hip, covering 2 pre-laid cap shingles at the bottom of the
hip. Go back over hip vents and fasten at 4” intervals.
If the vent is not being run the entire length of the hip,
use the cap shingles to create a transition. Use sealant to
fill any void left between the shingles and the remaining
top layer of the vent. Be sure to apply roofing sealant to
any spaces left by cap shingle used for transition. If 2 or
more sections of ridge vent are being joined together, an
end cap MUST be installed into each end of the joining
sections. Repeat on all hips.
Apply the cap shingles to the hip and then to the ridge.
Nail hip and ridge caps with roofing nails in a common
overlapping pattern. Nails should penetrate the wood
roof deck at least 3
⁄4”. For fastest installation, a coil nail
gun can be used as long as the minimum 3
⁄4” penetration
into the deck is maintained. It is important when installing
this vent that you maintain the pitch of the roof. The vent
has been installed properly if the bottom of the vent is flat
on the roof and the peak is slightly rounded.

end cap. Shape vent in V Shape. Pull the vent tight and
secure at about 10 feet. Pull the rest of the vent tight and
secure, inserting the end cap. Multiple lengths of vent
can be joined by butting the sections tightly together. End
cap should be inserted at the beginning and end of each
section.
4. Vent Placement on Hip
Install a minimum of 2 cap shingles at the bottom of the
hip. If the vent is not being run the entire length of the hip,
the vent should overlap a minimum of 2 cap shingles at
the end of the vent. Before installing the vent on the hip,
lay a bead of sealant on each side of the pre-cut slots.
This will create a seal on the step created by overlapping
pattern of the shingles. The bead of sealant should be
applied approximately 1” from the edge of the pre-cut
slot.
Note: For “Class A” Installation Only
For “Class A” Quarrix vent installation, follow steps 1,
2, 3 as stated above. Once the vent has been installed,
use a utility knife with a hook blade and remove the
corrugated plastic center section of the vent. Do this
for the hip and ridge.
This modified installation
meets the requirements for
UL790 “Class A”; standard
installation meets the
requirements for UL790
“Class C.” Follow remaining
steps 4, 5, 6 as stated.
INSTALLATION

19
Cut the slot prior to installing the last course of shingle
panels along the ridge in a re-roof or new construction
application (protective eye goggles should be worn
during this process). For 5
⁄8” profile 7” wide vents, cut a 2”
slot (1” on each side of ridge) along the ridge. A minimum
of 6” must be left uncut on each end of the ridge. Once
the slot is cut then measure and cut shingle panels to
fit along the ridge; panels should not obstruct the slot.
Once the panels are installed, the ridge is ready for vent
installation.
Retrofit with Stone-Coated Steel
If stone-coated steel is
already installed, the slot
can be cut from the pre-
paneled roof using a circular
saw with a combination
blade (reversed) or a Tenryu
Steel Pro blade (protective
eye goggles should be
worn during this process). For 5
⁄8” profile 7” wide vents,
cut a 2” slot (1” on each side of ridge) along the ridge. A
minimum of 6” must be left uncut on each end of the ridge.
Pull apart a precut section of the foam end cap found with
the vent, usually found in the first 3 feet of the roll. Use a
utility knife to make a cut in the StormStop material 1
⁄2”
on each side,
back from the
end of the
section (See
insets). Using
construction
adhesive or
sealant caulk,
coat both
sides of the
S t o r m S t o p
material where it has been cut back at the end of
the vent. Insert the foam end cap with the cut-back
StormStop material between the foam end cap and the
underside of the vent to assure a weather-tight seal.
STONE-COATED
STEEL ROOFS
Before installing the vent on the ridge a bead of sealant
is required between the stone-coated steel and the
underside of the ridge vent. This sealant should fill any
voids between the bottom of the vent and the surface
of the panel. Caulking and sealants shall be suitable for
exterioruseandberesistanttoweathering;useeitherbutyl
or polyurethane sealants. The caulking and the sealants
shall be compatible with and adhere to the materials to
which they are applied. Check sealant manufacturer’s
instructions and stone coated steel’s installation guide
for compatibility. Roll out or place ridge vent along the
entire length of slot also covering the 6” minimum uncut
ridge on both ends. When
using R-Series (Rigid Roll)
products, secure at the
lead edge, inserting the
end cap. Pull the vent
tight and secure at about
10 feet. Pull the rest of
the vent tight and secure,
inserting the end cap.
Multiple lengths of vent can be joined by butting the
sections tightly together. An end cap should be inserted
at the end of each section.
Attach vent to the roof deck by driving a nail or a #8 screw
in each of the two corners on both ends of the vent. Also,
drive two nails or #8 screws through the vent and foam
end cap to hold foam in place on the ends of the ridge
only. Fasteners should penetrate the wood roof deck at
least 3
⁄4”. It is recommended to fasten the vent to ridge
prior to stone-coated steel hip/ridge cap installation. Vent
should be secured every 5”.
It is important when installing this vent that you maintain
the pitch of the roof. The vent has been installed properly
if the bottom of the vent is flat on the roof and the peak is
slightly rounded. Install hip/ridge caps per manufacturer’s
installation guide. Each
hip/ridge piece should clip
together by inserting the
return (at the nose of each
piece) into the back clip,
which is located at the top
of the hip/ridge cap section.
Fasten cap to vent through
the back clip using #8 screws. Fasteners should penetrate
through the wood roof deck at least 3
⁄4”.

FLAT TILE
ROOFS
The slot must be cut on a new roof before field tile
installation. The amount of ventilation is controlled by
the length of slot cut along the roof ridge. Remember,
for the most attractive roofline, it is recommended that
Quarrix ridge vents be installed along the entire ridge of
the roof. For 5/8” profile vents, a 31
⁄2” slot should be cut
(13
⁄4” on each side of ridge). For 1” profile vents a 4” slot
should be cut (2” on each side of the ridge). A minimum
of 6” must be left uncut on each end of the ridge. Once
the slot is cut and the
battens are installed,
it is time to install the
field and trim tiles per
the tile manufacturer’s
installation instructions.
After field tile installation,
the ridge now is ready
for vent installation.
Pull apart a precut section of the foam end cap found with
the vent. Using a utility knife, make a cut in the StormStop
material 1
⁄2” on each side of the vent, back from the end of
the section. Using construction adhesive or sealant caulk,
coat both sides of the StormStop material where it has been
cut back at the end of
the vent. Insert the foam
end cap with the cut-
back StormStop material
between the foam end
cap and the underside
of the vent to assure a
weather-tight seal.
Before installing the vent on the ridge, a bead of sealant
is required between the roof tile and the under side of the
ridge vent. This sealant should fill any voids between the
bottom of the vent and the
surface of the tile. Caulking
and sealants shall be suitable for exterior use and be
resistant to weathering. The caulking and the sealants
shall be compatible with and adhere to the materials to
which they are applied. Check sealant manufacturer’s
instructions for compatibility. Roll out or place vent along
the entire length of slot also covering the 6” minimum
uncut ridge on both ends. Multiple lengths of vent can
be joined by butting the sections tightly together. An end
cap should be inserted at the end of each section.
4. Cap Tile Installation
It is important when installing this vent that you maintain

According to the APA-The Engineered Wood Association, continuous
ridge vents, like Quarrix Ridge Vent, can be used in conjunction with
a roof diaphragm and meet the requirements to withstand lateral
loads in seismic and high wind designs. Quarrix Ridge Vent can be
used in unblocked as well as blocked roof diaphragms.
According to the APA with an unblocked diaphragm, there is no
requirementforaconnectiontobemadebetweenunsupportededges
of adjacent panels. With an unblocked diaphragm-type construction
Quarrix Ridge Vent can be installed with no modification to the
published installation instructions. In an unblocked diaphragm, only
the 4-foot wide panel ends occur over and are nailed to common
framing. This is the most common type of diaphragm used in
standard residential construction.
According to the APA with a blocked diaphragm, the use of a
continuous ridge vent is slightly more challenging because all
edges of all adjacent panels must occur over and be attached to
common framing. This additional nailing provides a greater number
of fasteners available to transfer shear from one panel to another,
thus increasing the overall shear capacity and rigidity or stiffness of
the diaphragm. This is as true for the ridge as it is for other panels
occurring in a common plane. This can be done by placing blocking
in alternating spaces between the rafters or joists. At the location
where there is not blocking, the slot at the ridge that is cut for
venting, is increased in width to the required opening for proper
ventilation. At the location where there is blocking, the required nail
spacing shall be halved, so that twice as many nails are present to
make this connection in every other space.
How is proper attic ventilation achieved with alternating blocking
in a blocked diaphragm application?
With alternating blocking the determining factor for NFA (Net Free
Area) is the width of the slot cut at the ridge of the roof. Since the
length of the allowable venting area along the ridge is cut in half.
The width of the slot is increased to 2.5” to insure proper ventilation.
When venting with a blocked diaphragm, warm air travels through the
unblocked sections of the ridge, flowing over the blocked sections
of the ridge and exiting along the entire length of the ridge vent.
The warm air from the attic space will be properly vented using this
application. 5
⁄8” profile Quarrix Ridge Vent will provide 12.7 square
inches of NFA per lineal foot of the roof in this application. Quarrix
Ridge vent, when properly installed, meet or exceed the requirements
of all nationally recognized building codes for ventilation.

These charts represent the minimum length of Quarrix Ridge Vent, in combination with
soffit ventilation, required to properly ventilate your attic space. Determine the square
footage of attic space by multiplying length x width of the house. Find your approximate
square footage on the chart and read across.
The chart will tell you how much NFA is required at the ridge, the recommended
footage of Quarrix Ridge Vent, and the minimum square inches NFA of soffit ventilation
required. These charts utilize the F.H.A. Standard for Static Ventilation as found in H.U.D.
Requirements for Proper Ventilation - Ref: M.P.S. 403.3. They use the 1:300 ratio (1 sq.
ft. of ventilation for every 300 sq. ft. of attic space). Quarrix numbers are rounded up to
the nearest foot.
The numbers in these charts reflect the minimum lineal footage of slot that should be
cut into the ridge. For the most attractive roofline possible, it’s recommended that the
ridge vent be installed along the entire ridge and hips of the roof. See page 30 for metric
conversions of the charts.

DETERMINING YOUR
VENTILATION NEEDS

28800.438.2920 | quarrix.com
Step 1
Once house wrap has
been applied, install
a 3
⁄4” (19 mm) Quarrix
Furring Strip horizontally
just below the soffit
at the very top of the
house wall. Also install
a 3
⁄4” (19 mm) Furring
Strip horizontally at the
bottom of the wood on
the house wall.
Step 2
Install 3
⁄8” (10 mm)
Furring Strip every
16” on center using
fasteners that penetrate
plywood 1
⁄2”.
Step 4
Attach siding according
to building codes using
fasteners long enough to
sufficiently penetrate into
framing.
Step 3
If fasteners are used to secure the
tile to the roof, the penetration of the
fastener must be into the roof deck
for structural hold* according to the
manufacturer’s specification.
*Quarrix Tile Batten cannot be used for
structural support of the tile.
Step 1
Unfold Quarrix Tile Batten to full
8-foot length and align along pre-
chalked line. Nail or staple 2” in
from the starting edge. Move over
to the hinge of the Tile Batten
and nail or staple 2” from hinge
of the fold. Note: Power nail or
staple tools can be used to place
fasteners.
Step 2
Place a nail or staple 10” in from
each of the fasteners that have
already been placed. Place an
additional nail or staple in the
middle of the section for a total
of 5 fasteners per 4-foot section
of batten.
Repeat on other side of 4-foot
section of the batten. Use this nail
or staple pattern when fastening
the remaining battens to the roof
deck. Fasteners should penetrate
the roof deck a minimum
of 1
⁄2”. See manufacturer’s
specifications. Note: Use a utility
knife when cutting the tile batten
to desired length.
Step 3
Furring Strips should be
installed approximately
1” from the edge of
the wall. Furring Strips
should also be used
under trim, in corners
and around windows.
The furring strips should
be installed to support
the width of the trim.

Q. How does StormStop®
work?
A. The membrane material used in Quarrix Ridge Vent and
Quarrix Multi-Use Vent is a spun-bound non-absorbent
plastic. Twenty nine percent of our membrane is fiber.
The other seventy-one percent is open. This lightweight
membrane makeup allows air to pass through but stops
water. Water pools on the surface of the membrane but is
not allowed to penetrate it.
Q. Will StormStop reduce airflow?
A. The airflow of a ventilation system is determined by the
Net Free Area of the vent, the slot width and the ventilation
at the eave or soffit (a balanced system). The recommended
slot width for installation of Quarrix Ridge Vent, when used
with a balanced system, provides adequate airflow for
efficient ventilation.
Q. What is the NFA of the product?
A. The Net Free Area of the product is 12.7 inches per lineal
foot for the 5
⁄8” profile product and 19 inches per lineal foot
for the 1” profile product.
Q. Will the StormStop filter clog?
A. The material is not a filter, but is a special membrane. Unlike
products with a filter, the material is non-porous and will not
allow matter such as dirt or loose insulation to lodge within
it. Products that actually use a filter material are susceptible
to clogging.
Q. You do not have baffles, so will this product perform
as well as baffled products?
A.The most crucial element to the performance of a ventilation
system is that it is in balance. If an attic has a properly
balanced system, the airflow will move from the eaves and
the bottom of the attic to the top, pushing out heat and
moisture in a natural flow using air pressure, thermal effect
and diffusion. If the system were to be unbalanced, and the
NFA at the ridge is higher than at the eave, a reverse airflow
can occur causing an opposite effect to what is desired.
Baffles have no effect on achieving a balanced system. For
a system to be in balance there must be an equal or greater
amount of intake at the eaves than what is being exhausted
at the ridge.
Q. What other reasons is a non-baffled product better
than a baffled product?
A. Baffles are unattractive and easily seen on the roof. In
addition, plastic baffles can break off or deteriorate over
time. Baffles also are susceptible to clogging from leaves
and other debris.
Q. What about the Bernoulli effect?
A. The Bernoulli effect has to do with wind passing over
an object. When venting, a baffle is only as effective as the
environment in which it operates. A baffled venting system
only operates at its optimum efficiency when the wind passes
perpendicularly over the baffle at a precise angle. If there is
no wind over the baffle it does not aid in venting of the roof.
In addition, your ridgeline has to be facing the way the wind
blows for the baffle to perform. A baffle alone will not provide
adequate continuous ridge ventilation; it must be a part of a
balanced system.
Q. How easy is installation of Ridge Vent?
A. Our product easily rolls out and is quick and easy to install
using a coil nail gun. There is one simple additional step when
inserting end-caps. A small cut in the membrane must be
made to assure a proper seal at the end of the vent.
See page 14.
Q. Has the product been tested?
A. Yes! The product has been put through rigorous research
and development testing at Architectural Testing Institute in
York Pennsylvania. The results:

It withstood tests similar to DADE County protocol of
8.8 inches of rain per hour with 110-MPH winds and
easily passed.

It also passed the ICC snow simulation test at 35 MPH and
70 MPH with no infiltration. Quarrix Ridge Vents meet the
conditions of acceptance of the Dust Exposure Test with no
reduction in airflow.

Quarrix Ridge Vent are certified for performance by
Miami-Dade, Building Officials and Code Administrators
International, International Conference of Building Officials,
International Code Council, Texas Department of Insurance
and Underwriters Laboratories Class A or C.
Q. What pitches can it be used on?
A. Quarrix Ridge Vent and Multi-Use Vent can be used
3/12-20/12.
Q. Can this product be used on hip applications?
A. Yes, the same Quarrix Ridge Vent that is used on the ridge
will work well in hip applications. See page 17.
Q. Quarrix Ridge Vent works with any other applications?
A.Quarrix Ridge Vent works on hip, and Quarrix Multi-Use Vent
work on eave intake, ridge exhaust and shed applications.
Quarrix Ridge Vents also works under various types of roofing
materials such as flat tile, cedar shakes and shingles, stone-
coated steel and metal. See pages 14-22.
Q. What kind of warranty do Quarrix products have?
A. Quarrix Products (not including EZ-PLUG) carry a
manufacturer’s limited lifetime warranty! See page 32.
