Roof Drain Continuous Insulation

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.

Roof drain continuous insulation.

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. Rainwater that does not drain and remains standing collects dirt and debris that can damage or accelerate erosion of roof covering. In metal stud walls the requirement for continuous insulation in addition to the insulation within the stud space is new. 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.

Foamular insul drain insul drain drainage board is designed specifically for foundations to improve thermal foundation performance through a higher r value. At roof drains the 4 of insulation can taper down to 3 within the area of the drain sump. With increased insulation requirements in recent versions of the energy codes continuous insulation on the roof can allow the owner to meet thermal insulation requirements in both low slope roofs as well as cathedral ceilings and conditioned attics. Provisions for continuous insulation also occur in masonry walls.

Basically 4 of insulation is required with the only exception at roof drains. 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. Unlike typical insulation installed between framing members continuous insulation provides an uninterrupted thermal barrier for unparalleled performance.
