Rigid Insulation Slope To Roof Drain

Rigid insulation slope to roof drain.

Organic felt or inorganic coated glass facers. Drain locations and deck slope verification for ponding water or deflection. The dimensionally stable gemini drain set provides a 4 way slope to the roof drain to prevent ponding and premature roof failure. As a general rule if the insulation is two inches thick or less a 4 foot by 4 foot sump is sufficient.

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. 4 x4 1220mm x 1220mm. The first piece may go from 1 high to 1 high then the next piece will go from 1 high to 2 high. Proper slope to drain eliminates ponding which accelerates membrane aging and leads to roof leaks.

A typical interior roof drain assembly occupies about a 4 foot by 4 foot square area with a inch per foot tapered slope. A typical interior roof drain assembly occupies about a 4 by 4 square area with a per foot tapered slope. 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.

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. 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. Available with acfoam ii acfoam iii and facer technology one piece pre fabricated tapered panel. Tapered rigid insulation tapered rigid insulation is polyisocyanurate insulation or eps insulation custom manufactured to provide a 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. Tapered roof insulation systems. The dimensionally stable gemini dst provides a positive 4 way slope to the roof drain. Details matter when it comes to insulation performance the difference is in the details.

Because of its size and customization options tapered eps often can be installed in a single layer. Tapered insulation is only effective on simple drainage patterns with few penetrations.
