From higher frequency of wildfires to an overall focus on safety as more Americans work and school from home, fire safety is top of mind. How do Boral Building Products’ siding and trim materials compare to others when it comes to fire resistance?
Here’s a guide:
Fire Resistance of TruExterior Siding & Trim
All thicknesses, widths, and profiles of the TruExterior Siding & Trim product line are certified by the California Building Commission for inclusion on the Wildland-Urban Interface Zone (WUI) Products Listing, one of the strictest regulations on building products, systems, and assemblies in the country. The product line is part of a relatively small group of cladding materials approved for WUI-designated buildings. This means that architects and contractors can confidently specify the product for use throughout all areas of California, regardless of WUI restrictions.
Fire Resistance of Versetta Stone siding
Versetta Stone offers the look of stone and the ease of panelized installation—and a Class A fire rating meeting the requirements of the ASTM E 84 – fire spread & smoke test.
Versetta Stone can be used for interior fireplace surround applications.
Fire Resistance of Foundry Siding
Not only does Foundry Siding’s authentic looks separate it from other similar siding products, Foundry shakes and shingles contain PVC, which contributes to a 1A fire resistance rating. Siding made with polypropylene does not carry a 1A rating.
In addition, Foundry’s Grayne Shingle line is included on California’s WUI building materials listing.
As with any material, use of Boral Building Products’ siding and trim materials beyond the parameters to which they are designed could impact fire resistance. Have questions? Contact our customer service team today.
