Dow Building Solutions introduced the THERMAX™ Wall System, described as an integrated wall system for commercial steel-stud buildings that combines continuous exterior insulation, a water-resistive layer, and an air barrier.
The continuous thermal barrier insulates both the wall cavity and steel studs (which transfer heat at a much faster rate than wood studs), and moves the dew point from within the wall cavity, where it can cause problems, to the exterior. Finished with spray foam on the interior wall cavity, the system blocks air infiltration and meets fire code, the company says. A high system R-value (R-9 to R-24) can contribute to credits under the LEED (Leadership in Energy and Environmental Design) green-building rating system.
The system consists of THERMAX™ exterior insulation, sealed with WEATHERMATE™ flashings at sheathing joints, windows, and doors, and STYROFOAM™ Spray Polyurethane Foam (SPF). The wall system meets NFPA 285 Multi-Story Flammability Testing Criteria as required by the International Building Code, in addition to ICC requirements for continuous insulation, the air barrier, and the water-resistive barrier, the company says.
