Rigid Insulation Sloped To Roof Drain

Tapered rigid insulation is polyisocyanurate insulation or eps insulation custom manufactured to provide a slope.

Rigid insulation sloped to roof drain.

As a general rule if the insulation is 2 thick or less a 4 by 4 is sufficient. Because of its size and customization options tapered eps often can be installed in a single layer. A typical interior roof drain assembly occupies about a 4 by 4 square area with a per foot tapered slope. 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 gemini drain set is the only 4 x 4 drain sump that requires no assembly by the contractor. Tapered backwashes can also help reduce the insulation height at the roof edge. Rigid foam insulation provide performance and value in low slope roofi ng systems and are designed to be used over structural roof decks. The dimensionally stable gemini drain set provides a 4 way slope to the roof drain to prevent ponding and premature roof failure.

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. In contrast tapered expanded polystyrene eps rigid foam insulation is available in blocks up to 40 inches thick and can be cut to virtually any slope depending on the drainage needs of the building. This is the industry s first one piece pre cut drain sump. Tapered roof insulation systems.
