Thermally broken roof hatch

1509build01pA thermally broken roof hatch has a thermally broken frame and cover to minimize heat transfer and the effect of condensation to provide energy efficiency. The hatch is designed with an element of low conductivity integrated between interior and exterior surfaces of the cover and frame to reduce temperature transfer. The components also dampen vibration for reported improved acoustic performance against outside noise. The product has 3 in. of polyisocyanurate insulation with an R-value of 18 in cover and curb and a cover gasket to minimize air leakage. The hatch has counter-balanced lift assistance, automatic hold open, and uses the Bil-Clip flashing system.
