Taper System Flat Roof

Tapered insulation for low slope roofing when designing a low slope roof system over a substrate that is less than 12 a properly designed tapered insulation system becomes the foundation for a sound roofing system.

Taper system flat roof.

Flat tapered eps roofing insulation insulfoam taper is an engineered insulation consisting of a superior closed cell lightweight expanded polystyrene eps. 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 eps insulation provides the required positive slope to drain while retaining the structural and economic advantages of a flat roof deck. T apered roof system s are also know as tapered roof insulation.

It maintains long term thermal performance dimensional stability and consistent moisture resistance. 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. Standard material is johns manville enrgy 3tapered and flat polyisocyanurate roof insulation. Roofers install tapered roof tiles so water doesn t pool on the flat roof surface reducing roof leaks and damage to the upper membrane.

The standard tapered panel size is 4 x 4. 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. Taper is not recommended for use on level roof decks. When correctly installed tapered insulation helps eliminate problems due to ponding water and can extend the longevity of your low slope roofing system.

Eps effectively controls the transfer of heat within all roofing systems. Insulfoam i vii ii ix xiv and xv.
