The LIGHTWALL 3000 curtainwall from Exterior Technologies Inc. (EXTECH) accepts both insulated glass units (IGUs) and cellular polycarbonate glazing (CPG) panels in the same extruded aluminum, thermally broken, framing system.
“Our LIGHTWALL 3000 is one of the few curtain walls that properly accommodates both CPG and IGUs within the same system,” says EXTECH Director of Product Application and Development Kevin Smith, R.A. “This is accomplished by using deep glazing pockets, low-friction gaskets and controlled gasket pressure that allow for the thermal movement of polycarbonate, while still providing superior water and air infiltration resistance.”
