Product Overview
Reflective Insulation for Wall Cavity
Insulapack wall cavity insulation combines reflective aluminum foil layers with sealed bubble chambers to reduce radiant heat transfer inside wall assemblies.
The thin insulation profile allows installation between studs or structural framing where traditional insulation materials may require more space.
Technical Performance for Wall System
Insulapack reflective wall insulation helps control radiant heat transfer and improve thermal efficiency inside wall assemblies.
The multi-layer reflective structure supports energy-efficient building envelopes in commercial, residential, and metal building construction.

Why
Why Use This Product
Wall cavity insulation in commercial construction needs to perform within the constraints of the assembly — often with limited cavity depth and strict fire code requirements. Insulapack reflective bubble foil wall cavity insulation fits within standard stud cavities and installs without requiring an additional airspace. The multi-layer construction provides R-10.6 per inch of thermal resistance while meeting ASTM E84 Class A fire rating requirements. LEED compliant. Suitable for interior and exterior wall assemblies on commercial projects across Canada and the United States.
