Rigid Insulation Slope To Roof Drain

Many building codes contain requirements for minimum roof slope especially for new construction.

Rigid insulation slope to roof drain.

A tapered roof system is completely customized for every single roof from the materials used to how the insulation is laid out. It improves roof performance and longevity by draining water properly and in a timely manner. Other slopes are available and provide additional fl exibility for design. 4 x4 1220mm x 1220mm.

Available with acfoam ii acfoam iii and facer technology one piece pre fabricated tapered panel. Download insul drain data sheet pdf 372 kb. The dimensionally stable gemini dst provides a positive 4 way slope to the roof drain. 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.

Minimum slope of per foot as required by the international building code ibc toward roof drains or scupper drains leaving no fl at areas for ponding. If the insulation reaches 3 or thicker an 8 by 8 creates a more gradual slope while still providing the necessary momentum. 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. Take a closer look and the choice will be clear.

Tapered insulation is primarily used to meet slope requirements or to create positive drainage in an existing roof system. The use of foamular. Organic felt or inorganic coated glass facers. The dimensionally stable gemini drain set provides a 4 way slope to the roof drain to prevent ponding and premature roof failure.

All products in the acfoam polyiso roof insulation family are closed cell rigid foam insulation board flat or tapered. Fabric covered channels drain water from vertical foundation walls. As a general rule if the insulation is 2 thick or less a 4 by 4 is sufficient. Foamular insul drain insul drain drainage board is designed specifically for foundations to improve thermal foundation performance through a higher r value.

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. As a general rule if the insulation is two inches thick or less a 4 foot by 4 foot sump is sufficient.
