Thermally Broken Roof Hatch

Thermally Broken Roof Hatch

Thermally broken roof hatches feature R-20+ insulation and a frame and cover design that minimizes heat transfer between interior and exterior metal surfaces. The result is a product that resists harmful condensation and provides superior energy efficiency. The Thermally Broken design is available in all standard BILCO single leaf sizes (S,E,NB,L,GS,F) and special single leaf sizes are available upon request. (Patent Pending)
