6. 1.9 Cavity System
CAVITY
CONSTRUCTION
DETAILS AT
weathertex.com.au
To provide the best protection for your wall against moisture and mould related problems Weathertex highly recommends the use of a
cavity fixing system. Fixing over the Weathertex cavity system provides the best defence for your internal lining, frame, insulation and
cladding against sick home syndrome. A cavity system creates a space within the wall that allows airflow to remove any moisture that
accumulates in this space either from wind driven rain or condensation.
1.9.1 PREPARATION
Minimum requirements for fasteners must be followed when installing the Weathertex Cavity System. See the Fasteners Section when
selecting appropriate fasteners.
A suitable membrane must be installed between the timber frame and battens; see section on Wall Sarking Requirements. The membrane
can be secured by the timber battens as they are installed along a wall.
Care should be taken when installing bulk insulation to ensure the stud cavity is not over-filled. Over filling the stud cavity with bulk insulation
will impinge in the cavity created by the cavity battens and hence reduce its effectiveness, and may void warranty.
1.9.2 CAVITY BATTENS
Cavity battens provide the separation between the membrane on the wall frame and the cladding. Weathertex provides and recommends
the use of Weathertex Cavity Battens which are 1220 x 45 x 9.5mm. Check your local regulations and/or certifiers for recommended batten
thickness. If using battens other than Weathertex supplied cavity battens, fastener lengths should be increased to accommodate the batten
thickness.
Refer to Weathertex Cavity Fix Construction Details when installing Weathertex cavity battens. Cavity battens must be fastened to framework
at a minimum of 600mm centres. Butt-join the stud battens leaving a 5mm gap.
1.9.3 CAVITY CLOSER
To protect against vermin and other material entering the cavity, the base of the cavity must be sealed using the Weathertex Large or
Small Cavity Closer. Designed not to interrupt airflow in the cavity, a cavity closer must be installed at the base of the wall, above window
heads, inter-storey flashings and at other points where a cavity is created by the design. The bottom of the battens is inserted into the cavity
closer.
• Use 20mm Large Cavity Closer for: Classic weatherboards with 9.5mm cavity system
Fix the cavity closer to the base plate at 300mm centres along the closer with 30 x 2.8mm flat head galvanised nails. Butt-join the cavity
closers with a max 2mm gap and ensure they are fixed in a straight, level line. It is important that the openings in the cavity closer are kept
clear and unobstructed to allow free drainage and ventilation from the top to the bottom of the cavity.

10. 2.4 INSTALL: Classic
The following product specific product installation instructions are applicable for both direct fix (timber frame) and cavity fix (timber and
steel frame). Installation instructions in this section are to be used in conjunction with information and requirements given in previous
sections and the national and state building codes.
2.4.1 BASE OF THE WALL & FRAME PREPARATION
Check and straighten sub-structures as required. Establish ground clearance and weatherboard overhang requirements. For cavity
installation see cavity systems (section 1.10)/steel frames (section 1.9). For direct fix install wall sarking prior to installation, refer to AS
4200.2. Install appropriate flashing at the base of the frame to ensure separation of Weathertex from any concrete slabs.
2.4.2 CLASSIC WEATHERBOARDS INSTALLATION
Establish a horizontal datum around the perimeter of the building, measure
wall height from the datum to establish the number of weatherboard rows
required. Minimum overlap of 20mm for Classic and a minimum overlap of
25mm for Rusticated planks.
First Row: Fix a 35mm x 9.5mm strip of Weathertex weatherboard 5mm up from
datum. Level the bottom edge of the weatherboard to the datum line. Fasten
the bottom edge through the weathertex strip into the frame. Fit joiners as work
proceeds.
Successive Rows: Use the storey rod, lap gauge or joiner to position
weatherboards and maintain uniform rows. Check rows for level, a laps fasten
through weatherboards into stud . One fastener per stud located 12mm from
bottom edge and the ends of the board. Row heights around corners should be
checked as work progresses to prevent creep.
Please refer to construction details found on the Weathertex website for all
window, doors and penetrations.

2.4.3 SHINGLES PLUS INSTALLATION
Shingles are the only product in the Weathertex Natural range that
Weathertex permits painting. If you are painting the shingles you will need to
use a high quality tannin blocking exterior timber primer (water or solvent
based) to prime the shingles and any cut edges.
First Row: Set a horizontal datum line to align the first row. Allow a minimum
overlap of 40mm. Fix a 35mm x 9.5mm strip of Weathertex 25mm up from the
datum. Level the bottom edge of the board with the datum line. Fasten the
bottom edge through the Weathertex strip into the timber framing. Cut
Weathergroove joiner into 205mm joiners, fit these joiners as work proceeds.
Where weathertightness is required add a bead of suitable sealant in each
groove where the next row overlaps.

Shingles into the stud. Use one fastener per stud, located at least 30mm from
bottom edges and 12mm from ends. Fasteners per fastening guide for classic

Please refer to Weathertex Direct Fix Installation – Classic, Drgs. of 13.05.22 (18 pages), and Weathertex Cavity Installation – Classic, Drgs.
13.05.22 (18 pages) for details relevant to the Classic Weatherproofing Appraisal.
2.4.5 JOINING DETAILS
To accommodate movement, Weathertex’s joining methods have been designed to provide the correct spacing between adjoining
planks, and cover changes in dimensions of the product for specific wall lengths. Refer to length of wall requirements when choosing a
joining method. Any cut ends must be primed with a high quality tannin blocking exterior timber primer (water or solvent based).
2.4.5.1 JOINING: CLASSIC WEATHERBOARDS
Form joins between weatherboard ends using the relevant joiners for the selected profile - refer to the Accessories Section. Stagger
joins randomly or brick lay throughout the wall with joins being formed midway between the studs. When fitting the joiner, bring the
ends into moderate contact with the splayed edges or nibs within the joiner. Do not force ends tightly together. It is advisable to prepaint
plank ends when using Traditional Joiners to avoid white lines either side of the Accessory after possible contraction of construction
components in dry conditions. Simply cut joiners to fit at window heads, sills and eaves as required.
NOTES:
1. Avoid penetrating PC/ABS joiners with fixings during the installation process. This may cause the joiner to crack after the
installation. Where necessary predrill the fixing position through the joiner prior to fixing.
2. On the first row of Weathertex Rusticated remove leg gauge from the back of the joiner
3. Refer to length of wall requirements for continuous walls over 11m long.
