![]() The certificate is for low emissions of volatile organic compounds (VOCs). The paperless drywall, which incorporates glass mats on the drywall surface, is the first and only moisture and mould-resistant paperless interior drywall product to receive a GreenGuard certification from the U.S.-based GreenGuard Environmental Institute (GEI). While there are other mould-resistant drywall products on the market, none are paperless and none are geared to pre-rock applications, he points out. “In a country like Canada where weather is a factor in most construction projects, it is something for architects and builders to seriously consider.”ĭensArmor Plus was introduced to the Canadian market in 2002, but it hasn’t been used in pre-rock applications until the Kitchener project. ![]() “We allowed ourselves 10 days to finish this portion of the project, based on the original schedule, but we were able to complete all of the installation in just 4.5 days,” he says, adding no special tools are required for the drywall’s installation.ĭerek Geisel, field sales manager for Georgia-Pacific Canada, says DensArmor Plus is promoted for “pre-rock” applications (installation before the building is closed in) so the building team can “potentially condense” the construction schedule. Sommerfeld, who kept track of labour costs for the steel and 20,000 square feet of fire-rated wallboard on all the I-beams and columns on the second floor, says the big plus was that no subtrades were working on the floor because of the inclement weather, so AKS could work freely and quickly. Water from melting ice froze and formed icicles on the face of the paperless drywall, but not a single sheet showed defects or mould growth, says Sommerfeld.įurthermore, the product lived up to claims by Georgia-Pacific that while it costs 30 per cent more than traditional drywall, it more than makes up for it in labour savings. One of the worst days was in March during a rapid thaw-freeze. Over a seven-month period, it was pelted by 26 inches of rain, snow, hail and sleet and it withstood temperatures ranging from -13 Celsius to +34 Celsius. The contractor also put up 8,000 square feet of the ½ inch version of the product in the party walls and stud walls. AKS installed 20,000 square feet of 5/8-inch fire-rated DensArmor Plus on the first floor of the building before the windows, doors, exterior walls or the roof was in place. Sommerfeld says the drywall proved to be even more durable than he expected. Normally, drywall goes in after the roof goes on, but the weather-resistant product changed that plan. Last winter, the contractor installed 56,000 square feet of the drywall at a 68-unit condo project in Kitchener, much of it before the roof was completed.
