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.

Other slopes are available and provide additional fl exibility for design. As a general rule if the insulation is 2 thick or less a 4 by 4 is sufficient. Tapered insulation is primarily used to meet slope requirements or to create positive drainage in an existing roof system. A tapered roof system is completely customized for every single roof from the materials used to how the insulation is laid out.

A typical interior roof drain assembly occupies about a 4 by 4 square area with a per foot tapered slope. Take a closer look and the choice will be clear. If the insulation reaches 3 or thicker an 8 by 8 creates a more gradual slope while still providing the necessary momentum. The use of foamular.

Organic felt or inorganic coated glass facers. All products in the acfoam polyiso roof insulation family are closed cell rigid foam insulation board flat or tapered. 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. Fabric covered channels drain water from vertical foundation walls.

A typical interior roof drain assembly occupies about a 4 foot by 4 foot square area with a inch per foot tapered slope. The standard tapered panel size is 4 x 4. Download insul drain data sheet pdf 372 kb. 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.

Available with acfoam ii acfoam iii and facer technology one piece pre fabricated tapered panel. It improves roof performance and longevity by draining water properly and in a timely manner. 4 x4 1220mm x 1220mm. Foamular insul drain insul drain drainage board is designed specifically for foundations to improve thermal foundation performance through a higher r value.

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. The dimensionally stable gemini drain set provides a 4 way slope to the roof drain to prevent ponding and premature roof failure. Because of its size and customization options tapered eps often can be installed in a single layer.
