Roof Drain Continuous Insulation

If the added insulation layer is tapered the slope provided can improve drainage performance of the roof.

Roof drain continuous insulation.

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. Foamular insul drain insul drain drainage board is designed specifically for foundations to improve thermal foundation performance through a higher r value. 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. Continuous insulation for commercial roofs don t forget your hat.

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. 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. 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.

Unlike typical insulation installed between framing members continuous insulation provides an uninterrupted thermal barrier for unparalleled performance. At roof drains the 4 of insulation can taper down to 3 within the area of the drain sump. Provisions for continuous insulation also occur in masonry walls.
