Performance, Air Pressure Differences
• Dead loads applied as per test
• Wall is approx. 8’x10’.
• Real world construction
• L bracket support structure,
would need to be translated to
other systems
• Load cycling from 0 > 60 psf, >
-60 psf > +90 psf > -90 psf
No damage of any part of system
reported. Tested to negative and
positive pressures exceeding 90psf
(nearly 200mph)
ASTM C67 Brick Water Absorption,
Compressive Strength, Freeze Thaw
See test ASTM C67 Strength, minimum is
3000 psi, Corium 6700 psi average
Water absorption max allowed 17 %,
Corium 9.8% after 5 hour boil
Saturation coefficient average 67%
max allowed 78%
BCRL BM1:1993 standard developed
by CERAM
Freeze Thaw Testing for Brick
• Procedure based on British
standard BS3921:1985
• 100 cycles
• Brick and mortar joint tested,
installed in rails(slips)
• Tested after immersion in water
for 7 days
• Cycle -15C and +25C
• Inspected at 10, 50 and 100
cycles
No damage of brick, mortar or slips
appeared
Expectation of Performance of
Colorcoat HPS200 Rails in the
Corium System
Dr Graeme Peacock of Corus UK Ltd.
Supplier of Colorcoat HPS200,
Confidex and Galvalloy
• Analysis of possible failure
mechanisms and evaluation of
projected lifespan of coating and
rail.
• Explanation of product’s history.
• Explanation of the coating
structure.
• Explanation of galvanization is
superior to commodity galv
steel.
• HPS 200 used in protecting
metal cladding and roofing for
55 years (report written in
2005)
• If there was a risk its UV, and
coatings and rail don’t see UV
• Exposed it has 30 year
guarantee eg roofing
• Expectation of coating,
galvanization and steel system is
in excess of 60 years.
• Does not account for
redundancy in structural system.

Drained Cavity System
• Traditional system, allowing for drainage
• Often called ‘rainscreen’ which is
different than ventilated façade.
• Expect water infiltration, and drainage.
Does not expect ventilation from top and
bottom.
Define: Brick Rainscreen, isn’t all brick rainscreen?
State of the nation in Brick
• The Market
• Commercial, non-combustible, mid to high rise construction.
• Architecture matters.
• Public and private buyers
• Still loved by many and specified by most.
• Threats to Brick
• Replacement of brick technologies for traditional brick. ie Precast with brick; mechanically
attached brick, adhered brick. Mason’s share diminishing.
• Precast, Curtain wall, ACM, Rainscreen facades eat into brick choices.
• Masonry contractors
• Labour shortages, retiring masons, reducing supply.
• Price is constrained, creating pressure on Masonry Contractors.
• Space restrictions on site impacting choice for traditional masonry.

• Aesthetics:
• Image, color, texture, module (grid) size and orientation,
joint design and fastening
• Function:
• Weight, panel sizes, wind load requirements
• Impact and scratch resistance
• Durability and Life span and the warranty
• Weathering and UV resistant
• Ability to meet code requirements
• Maintenance and Cleaning, chemical resistance
• Sustainability: FSC, LEED, EPD, LC Analysis
• Energy efficiency (both cooling and heating)
• Economic:
• Material cost, Optimization and cost of fabrication and
Ease of installation

• Labour shortages
• Restrictions to one role
• Speed
• Onsite requirements in space, equipment

Brick-laying robots have been
developed to address the

What’s wrong
• Number of ties
• Penetrations of AVB
• Thermal bridges if not
this tie
• Thickness of
insulation ie code
compliance
• Dependence on
excellent installation

Building envelope concerns conventional systems
Thermal bridges
• Windows and doors
• Ties
• Ledges
Continuous insulation

Precast to slab details Issues:
• Thermal Bridge
• If not sandwich
panel, R value

• Use of slab area
• Typical in
Ontario is single

slab. No R Value,

thermally
bridged
Typical uninsulated single panel

• Thickness
• Slab usage
• Slab edge thermal bridge
• No of parts
• All placed with a crane
• Slab thickness for weight
• Caulking joint
But cheap, and average
buyer does not know

Labour Quality
Complicated Heavy
Current Building Envelope Issues impacting choice
While in the past building envelope conventions allowed standard details of traditional brick and precast, newer
standards across Canada, and those that will be coming soon, make it more and more difficult. Thin cladding outside
all exterior insulation cavity lend themselves more easily to these performance standards.
• Insulation between studs not satisfactory any more.
• Continuous AVB outside structure key to performance.
• Brick impact:
• Many ties piercing AVB,
• possibly thermal bridges.
• Installation quality key to satisfactory performance.
• Brick ledges are very deep, and thermal bridges (is there a tested thermally broken brick ledge?)
• Precast:
• Thick insulation requirements make sandwich panels either impossible or expensive, taking up floor slab space (are they possible?)
• Thermally broken cladding insulation cavities of 4-6” standard for thinner lighter weight cladding for 10 years, modelled by
experts and installed across the country.

Does not expect ventilation from top and bottom. Define: Brick Rainscreen, isn’t all brick rainscreen?
  • 7. State of the nation in Brick • The Market • Commercial, non-combustible, mid to high rise construction. • Architecture matters. • Public and private buyers • Still loved by many and specified by most. • Threats to Brick • Replacement of brick technologies for traditional brick. ie Precast with brick; mechanically attached brick, adhered brick. Mason’s share diminishing. • Precast, Curtain wall, ACM, Rainscreen facades eat into brick choices. • Masonry contractors • Labour shortages, retiring masons, reducing supply. • Price is constrained, creating pressure on Masonry Contractors. • Space restrictions on site impacting choice for traditional masonry. 72020 www.facadesystemsinc.com

  • 52. Current Building Envelope Issues impacting choice While in the past building envelope conventions allowed standard details of traditional brick and precast, newer standards across Canada, and those that will be coming soon, make it more and more difficult. Thin cladding outside all exterior insulation cavity lend themselves more easily to these performance standards. • Insulation between studs not satisfactory any more. • Continuous AVB outside structure key to performance. • Brick impact: • Many ties piercing AVB, • possibly thermal bridges. • Installation quality key to satisfactory performance. • Brick ledges are very deep, and thermal bridges (is there a tested thermally broken brick ledge?) • Precast: • Thick insulation requirements make sandwich panels either impossible or expensive, taking up floor slab space (are they possible?) • Thermally broken cladding insulation cavities of 4-6” standard for thinner lighter weight cladding for 10 years, modelled by experts and installed across the country. 52 Make less wordy – pictures?
