Wildfire Exterior ProtectionApplications
Advanced Building Technology (ABT) has multiple fire-rated products for exterior finishes.
The ultimate exterior insulated finishing panel system for walls or roof is our Protected Insulation Cladding System (PICS), which is Noncombustible, Maintenance Free, Insulating, Moisture and Sound Barrier. It combines a substrate of our ¼” thick Fiber Cement Board (FCB) sheets bonded to foam insulation of various thicknesses in a ready to install panels 2’ x 4’ up to 4’ x 8’. The FCB can also be used without foam insulation for other applications. This is finished with our noncombustible, colorized spray-on stucco texture WallGuard topcoat that has a has a 20 year warranty and adds additional fire resistance and reflective R-value to the wall.
Working with a substrate of OSB or equivalent and a building wrap applied to the substrate, the following outlines the steps required in each process.

Performance Data
- FIRE: Rated "Non-Combustible"
- Class A after passing the rigorous NFPA 285 test. WallGuard or RoofGuard coating is applied on the exterior (either spray-on, roller or brush) with a thickness of 4.5mil did not support flame spread or fire penetration during 35-minute fire test reaching 1,675 ℉.
- MOISTURE: 4 Year Wind-Driven Rain and Snow Test
- The membrane is permeable (breathable) allowing interior water vapor to escape, but is a barrier to rain and snow similar to house wraps or waterproof Gore-Tex garments. Product is also resistant to fungus, mold, and mildew.
- ELONGATION
- Tested to 600%+ elongation at 77 F. and returns to its original dimensions with no deformation and 100% memory retention.
- SOLAR
- Passed accelerated weathering and solar exposure of 500 hours exposure (equivalent to 4 years) with no degradation or evidence of checking, cracking, chalking or loss of coating.
- INSULATION>
- WallGuard and RoofGuard adds R-4.6 to the FCB substrate and 1-½" of foam insulation adds R-7.7 for a total wall insulation value of R-12.5; which reduces the cost of air-conditioning by 30% and heating by 60%.
- ANNUAL MAINTENANCE: None required
- But if damaged can be easily repaired with paintbrush or roller application of WallGuard. Any dust buildup can be removed with a garden hose.
- REPAIR CRACKED STUCCO
- Apply WallGuard (select from over 1,400 colors) with a brush, roller or spay-on; which will coat the stucco for a long lasting, fade resistant fresh appearance with a water-proof membrane filling cracks up to 1/16" wide. For wider cracks and older stucco that is chalking, use our Application Guide to first pre-wash, then dry before pre-filling the cracks with caulking and then applying WallGuard.
- WARRANTY
- 20-Years provided by the manufacturer, which has never had a claim submitted during the 35-year history of the products.
The Marriott Residence Inn Alberta, Canada project was completed in 2000. WallGuard was selected over traditional stucco for the 96,000 sq. ft. of exterior finish, because of its superior performance, durability, and maintenance free properties plus it reduced the labor and material cost by 44% saving $178,600. WallGuard was also used for the walls and ceiling of the indoor pool area. In the 21+ years since installation, the WallGuard coating has not required any repair or maintenance and has protected the exterior walls and interior pool walls and ceiling from the harsh conditions with no fading, peeling or cracking ensuring a clean and welcoming fresh appearance for the hotel guests. The property has been inspected every 5 years to ensure that it continues to perform as expected. The hotel owners and maintenance staff report that the WallGuard coating has been \"maintenance free\", which is a major saving in their annual operating budget costs. It has been rebranded as Lakeview Signature Inn located at 2622 39 Ave NE, Calgary.
