Tapered Roof Insulation

Flat tapered eps roofing insulation insulfoam taper is an engineered insulation consisting of a superior closed cell lightweight expanded polystyrene eps.

Tapered roof insulation.

Tapered acfoam ii product description. Tapered polyiso insulation provides a logical and economical answer for roofs that do not permit adequate positive drainage like low slope roofs. Acfoam tapered roof insulation helps prevent material waste reduces the roof profile and reduces fastening costs. 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. When correctly installed tapered insulation helps eliminate problems due to ponding water and can extend the longevity of your low slope roofing system. 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.

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 from atlas roofing corporation is designed to create positive drainage with the highest r values per inch of any rigid board insulation in the industry. 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. When correctly installed tapered insulation helps eliminate problems due to ponding water and can extend the longevity of your low slope roofing system.

Tapered polyiso minimizes the negative effects of ponding water and extends the service life of a roof. 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. Carlisle s tapered insulation helps promote rooftop drainage while providing excellent insulating value. Tapered rigid insulation is polyisocyanurate insulation or eps insulation custom manufactured to provide a slope.

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. Designing an effective tapered insulation system is crucial in assuring this success.
