Tapered Roof Insulation

Carlisle s tapered insulation helps promote rooftop drainage while providing excellent insulating value.

Tapered roof insulation. The roof consists of pre designed pieces of expanded polystyrene having a slope of 1 8 3 16 or 1 4 per foot as required. Foam control plus tapered roof insulation high compressive strength of 15 25 40 or 60 psi high r value that never changes and is stable over time closed cell insulation with superior moisture resistance high drying potential to rapidly release absorbed moisture meets code requirements for. Tapered roof insulation designed to provide positive drainage of water. Tapered acfoam ii product description.

The key to successful tapered insulation design is doing the necessary analysis of the project to confirm field conditions such as dimensions drain locations and deck slope verification for ponding water or deflection. Acfoam tapered roof insulation helps prevent material waste reduces the roof profile and reduces fastening costs. Insulfoam i vii ii ix xiv and xv. The first piece may go from 1 high to 1 high then the next piece will go from 1 high to 2 high.

Tapered polyiso minimizes the negative effects of ponding water and extends the service life of a roof. Insulfoam taper is cut from the same high quality eps as our flat insulroof products and meets or exceeds the requirements of astm c578 standard specification for rigid cellular polystyrene thermal insulation. Tapered protective perlite based cover board or low thermal insulation board proven to reduce blistering in hot asphalt applications. Designing an effective tapered insulation system is crucial in assuring this success.

When correctly installed tapered insulation helps eliminate problems due to ponding water and can extend the longevity of your low slope roofing system. When correctly installed tapered insulation helps eliminate problems due to ponding water and can extend the longevity of your low slope roofing system. It is readily available in the two most popular and efficient tapers 1 8 3 18 mm per foot 305 mm 1 and 1 4 6 35 mm per foot 3 18 mm 2. 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.

Flat tapered eps roofing insulation insulfoam taper is an engineered insulation consisting of a superior closed cell lightweight expanded polystyrene eps. The added thickness to produce slope to drain is a positive factor in today s energy conscious society.
