Our thermal spacer made from low-conductivity fiberglass material greatly reduces thermal bridging, improving the effective thermal resistance of the exterior wall. The Cascadia Clip makes ASHRAE 90.1 or NECB 2011 compliance simple and cost-effective.
Cascadia's Fiberglass Curtain Wall Vent Adaptor allows the thermally weakest part of curtain wall systems, the operable vents, to realize excellent thermal performance by using a fiberglass sash in place of aluminum. This improves the thermal performance of the entire curtain wall system, enabling greater glazing areas.
