Roof Drain Continuous Insulation

Continuous insulation for commercial roofs don t forget your hat.

Roof drain continuous insulation.

Rainwater that does not drain and remains standing collects dirt and debris that can damage or accelerate erosion of roof covering. Integrating tapered polyiso system with staggered joints into a roof s design will not only improve the thermal performance but also can improve drainage and thus overall longevity of the system. At roof drains the 4 of insulation can taper down to 3 within the area of the drain sump. Continuous insulation ci with its rigid foam material properties can cover entire surfaces and be fixed to either the inside or outside of exterior walls.

If the added insulation layer is tapered the slope provided can improve drainage performance of the roof. Continuous insulation products can also serve as the water resistant barrier and air barrier for a structure providing a 3 in 1 building envelope solution. In addition to boosting r values thermal performance which prevents heat from escaping ci also reduces moisture damage in the building envelope by lowering condensation within the envelope assembly resulting from vapor diffusion. Basically 4 of insulation is required with the only exception at roof drains.

Foamular insul drain insul drain drainage board is designed specifically for foundations to improve thermal foundation performance through a higher r value. In metal stud walls the requirement for continuous insulation in addition to the insulation within the stud space is new. Provisions for continuous insulation also occur in masonry walls.
