Rigid Insulation Sloped To Roof Drain

This is the industry s first one piece pre cut drain sump.

Rigid insulation sloped to roof drain.

Tapered backwashes can also help reduce the insulation height at the roof edge. The first piece may go from 1 high to 1 high then the next piece will go from 1 high to 2 high. 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.

The gemini drain set is the only 4 x 4 drain sump that requires no assembly by the contractor. 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. Backwash overlayed onadjacent flat over structural slope when roof drains are located a great distance away from a sloped roof edge more than 48 it can be more cost effective to use a tapered backwash.

Tapered roof insulation systems. 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 foam insulation provide performance and value in low slope roofi ng systems and are designed to be used over structural roof decks. As a general rule if the insulation is 2 thick or less a 4 by 4 is sufficient.
