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.

Roof drain continuous insulation. Unlike typical insulation installed between framing members continuous insulation provides an uninterrupted thermal barrier for unparalleled performance. Fabric covered channels drain water from vertical foundation walls. Provisions for continuous insulation also occur in masonry walls. 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.

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 ci with its rigid foam material properties can cover entire surfaces and be fixed to either the inside or outside of exterior walls. 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. If the added insulation layer is tapered the slope provided can improve drainage performance of the roof.

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. 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.
