Rigid Insulation Slope To Roof Drain

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 insulation slope to roof drain.

4 x4 1220mm x 1220mm. The dimensionally stable gemini dst provides a positive 4 way slope to the roof drain. Gradually tapered sumps formed in the insulation to facilitate localized drainage at drains. Tapered rigid insulation tapered rigid insulation is polyisocyanurate insulation or eps insulation custom manufactured to provide a slope.

Drain locations and deck slope verification for ponding water or deflection. A typical interior roof drain assembly occupies about a 4 foot by 4 foot square area with a inch per foot tapered slope. If the insulation reaches 3 or thicker an 8 by 8 creates a more gradual slope while still providing the necessary momentum. Tapered roof insulation 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 two inches thick or less a 4 foot by 4 foot sump is sufficient. The dimensionally stable gemini drain set provides a 4 way slope to the roof drain to prevent ponding and premature roof failure. Available with acfoam ii acfoam iii and facer technology one piece pre fabricated tapered panel.

A typical interior roof drain assembly occupies about a 4 by 4 square area with a per foot tapered slope. Design assistance services are offered as a courtesy to the roofing. 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. Because of its size and customization options tapered eps often can be installed in a single layer.

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. Tapered insulation is only effective on simple drainage patterns with few penetrations. 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. Details matter when it comes to insulation performance the difference is in the details.

As a general rule if the insulation is 2 thick or less a 4 by 4 is sufficient. Elastizell low density insulating concrete roof decks acheive positive drainage in new and reroofing construction.
