Rigid Insulation Sloped To Roof Drain

Thermapink tapered roof insulation provides a thermally effi cient moisture resistant positive drainage slope for use under single ply or other types of roofi ng systems.

Rigid insulation sloped to roof drain.

Tapered backwashes can also help reduce the insulation height at the roof edge. The dimensionally stable gemini drain set provides a 4 way slope to the roof drain to prevent ponding and premature roof failure. Tapered rigid insulation is polyisocyanurate insulation or eps insulation custom manufactured to provide a slope. If the insulation reaches 3 or thicker an 8 by 8 creates a more gradual slope while still providing the necessary momentum.

A typical interior roof drain assembly occupies about a 4 by 4 square area with a per foot tapered slope. Because of its size and customization options tapered eps often can be installed in a single layer. The gemini drain set is the only 4 x 4 drain sump that requires no assembly by the contractor. Rigid foam insulation provide performance and value in low slope roofi ng systems and are designed to be used over structural roof decks.

Over the course of the roof system the tapered insulation will create a slope toward the drains which typically ranges from 1 8 slope 1 down every 8 to slope 1 down every 2. The first piece may go from 1 high to 1 high then the next piece will go from 1 high to 2 high. Tapered roof insulation systems. As a general rule if the insulation is 2 thick or less a 4 by 4 is sufficient.
