Tapered roof insulation details.

Acfoam tapered roof insulation helps prevent material waste reduces the roof profile and reduces fastening costs. Insulfoam taper is an engineered insulation consisting of a superior closed cell lightweight expanded polystyrene eps. Carlisle s tapered insulation helps promote rooftop drainage while providing excellent insulating value. Tapered acfoam ii product description.

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. However tapered lightweight insulating concrete should be evaluated as an alternate to tapered insulation as it may be more efficient due to the roof configuration details and location. Standard material is johns manville enrgy 3tapered and flat polyisocyanurate roof insulation. When correctly installed tapered insulation helps eliminate problems due to ponding water and can extend the longevity of your low slope roofing system.

Generally tapered insulation is the most cost effective method to achieving positive drainage on low slope commercial roof replacements. Specifications all dimensions are nominal board size. Insulfoam taper offers a long term stable r value and has excellent dimensional stability compressive strength and water resistance properties. Sarnatherm iso tapered is a sloped rigid closed cell polyisocyanurate insulation board with fiber reinforced felt facers.

Full details are available on the tapered acfoam product pages. 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. Tapered polyiso minimizes the negative effects of ponding water and extends the service life of a roof. Sarnatherm tapered is designed to achieve positive drainage prevent ponding water and is suitable for use in new construction and re roofing with sarnafil or sikaplan membranes.

That makes the total cost around 5 724 00. 100 to 200 f 73 3 to 93 3 c dimensional stability. On average it cost 2 35 per square feet to have it installed so if you have a 2 400 sq of roof. Tapered foam roofing panels are affordable and easily installed.

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. The tapered insulation at the roof drain keeps rainwater flowing off the roof.
