Developing the design criteria for a roof drainage plan that will perform with the roofing system to drain the roof is critical prior to.
Tapered insulation roof system.
Manufactured from lightweight molded polystyrene tapered roof insulation is a value engineered system that has been proven in new and reroof applications all over the country.
Tapered acfoam ii product description.
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.
After the decision has been made to use a tapered roof insulation system designers architects and specifiers must determine which tapered roof insulation system is best.
A tapered roof system is completely customized for every single roof from the materials used to how the insulation is laid out.
The goal of tapered roof insulation systems is to reduce or eliminate the amount of ponding standing water on the membrane when the roof deck does not provide adequate 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 down every 8 to slope 1 down every 2.
When correctly installed tapered insulation helps eliminate problems due to ponding water and can extend the longevity of your low slope roofing system.
Flat tapered eps roofing insulation insulfoam taper is an engineered insulation consisting of a superior closed cell lightweight expanded polystyrene eps.
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.

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.
Tapered insulation systems play a critical role in moving water off a low sloped roof and create the foundation needed for a roof system that will perform for the long term.
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.
