Roof Drain Continuous Insulation

Basically 4 of insulation is required with the only exception at roof drains.

Roof drain continuous insulation.

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. 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. Foamular insul drain insul drain drainage board is designed specifically for foundations to improve thermal foundation performance through a higher r value. Rainwater that does not drain and remains standing collects dirt and debris that can damage or accelerate erosion of roof covering.

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. Fabric covered channels drain water from vertical foundation walls. Continuous insulation for commercial roofs don t forget your hat. In metal stud walls the requirement for continuous insulation in addition to the insulation within the stud space is new.

If the added insulation layer is tapered the slope provided can improve drainage performance of the roof. Unlike typical insulation installed between framing members continuous insulation provides an uninterrupted thermal barrier for unparalleled performance. 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.
