Roof Drain Continuous Insulation

Continuous insulation for commercial roofs don t forget your hat.

Roof drain continuous insulation.

At roof drains the 4 of insulation can taper down to 3 within the area of the drain sump. Basically 4 of insulation is required with the only exception at roof drains. 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.

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. Fabric covered channels drain water from vertical foundation walls. Unlike typical insulation installed between framing members continuous insulation provides an uninterrupted thermal barrier for unparalleled performance. Rainwater that does not drain and remains standing collects dirt and debris that can damage or accelerate erosion of roof covering.

Foamular insul drain insul drain drainage board is designed specifically for foundations to improve thermal foundation performance through a higher r value. 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. 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.
