With New York City’s 80×50 initiative to reduce greenhouse gas (GHG) emissions 80 percent by 2050, the stakes are high for the city to adopt progressively more stringent energy codes. Similarly, the Sustainable DC Plan professes the lofty goal of making the nation’s capital “the greenest, healthiest, and most livable city in the nation.”

Innovations reduce air leakage for energy efficient rolling steel door

Print

Until recently, air leakage was not a consideration in the rolling steel door industry. It was thought to be an impossible task—how do you stop air from coming through a door that is slatted? However, as codes became more stringent regarding reductions in air leakage, it started limiting the ability for architects to specify the best closure product for their application.

Insulation is a critical component to specify when designing a functional, cost-effective, and energy-efficient building. One method to insulate a building is by installing 50 to 152 mm (2 to 6 in.) of rigid foam insulation on the exterior side of the wall framing. Two of the most frequently installed types of rigid foam insulation are expanded and extruded polystyrene (EPS and XPS).

The fluid-applied air barrier (FAAB) concept was originally a Canadian-developed technology from more than 40 years ago. Back in the early 1970s, the genesis was an adhesive combining air- and vapor-retarding characteristics—eventually, this material would find its way into building codes.
