Rigid Insulation Slope To Roof Drain

As a general rule if the insulation is 2 thick or less a 4 by 4 is sufficient.

Rigid insulation slope to roof drain.

Gradually tapered sumps formed in the insulation to facilitate localized drainage at drains. A typical interior roof drain assembly occupies about a 4 by 4 square area with a per foot tapered slope. 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. Drain locations and deck slope verification for ponding water or deflection.

Tapered roof insulation systems. Because of its size and customization options tapered eps often can be installed in a single layer. 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. Developing the design criteria for a roof drainage plan that will perform with the roofing system to drain the roof is critical prior to the bid process and roof system installation.

The dimensionally stable gemini drain set provides a 4 way slope to the roof drain to prevent ponding and premature roof failure. Elastizell low density insulating concrete roof decks acheive positive drainage in new and reroofing construction. Organic felt or inorganic coated glass facers. 4 x4 1220mm x 1220mm.

Proper slope to drain eliminates ponding which accelerates membrane aging and leads to roof leaks. Tapered insulation is only effective on simple drainage patterns with few penetrations. Available with acfoam ii acfoam iii and facer technology one piece pre fabricated tapered panel. The dimensionally stable gemini dst provides a positive 4 way slope to the roof drain.

A typical interior roof drain assembly occupies about a 4 foot by 4 foot square area with a inch per foot tapered slope. Details matter when it comes to insulation performance the difference is in the details. Rigid foam insulation provide performance and value in low slope roofi ng systems and are designed to be used over structural roof decks. If the insulation reaches 3 or thicker an 8 by 8 creates a more gradual slope while still providing the necessary momentum.
