Polyiso Roof Insulation Assembly

Hd polyiso roof cover boards provide the protection of traditional material options with the added performance of thermal insulation.

Polyiso roof insulation assembly.

By blocking thermal bridging a polyiso continuous insulation system increases the overall thermal performance of a wall assembly and a building. An fm class 1 designation means the roof assembly has been subjected to a series of tests in addition to external and internal fire exposure including wind uplift water leakage and impact resistance. A typical 0 5 thick hd polyiso roof cover board has an r value of 2 5. Polyiso can be installed on both commercial and residential structures on the roof or in the wall.

Multi layering of polyiso roof insulation. Polyiso roof insulation is the most widely used product for low slope commercial roofing and provides a high r value that helps meet today s energy code requirements without the added thickness or weight of other products. An insulation board made of glass fiber reinforced cellulosic felt facers bonded to a core of isocyanurate foam. A polyiso continuous insulation system keeps energy and heat loss to a minimum increasing the building s energy efficiency and leading to lower monthly operating costs.

All atlas acfoam polyiso insulation boards are qualitymark certified providing consumers an easy way to identify premium products that meet or exceed building codes for the best in roof performance. When it comes to thermal efficiency and a wide range of building applications polyiso insulation is the 1 insulating material available today. Polyiso remains the only foam plastic insulation product for direct application to steel roof decks to earn fm approval for class 1 roof systems. Polyiso is an easy cost effective sustainable and energy efficient construction material.

Polyiso is used as a continuous insulation and commands an impressive market share. There s a reason polyiso rigid foam insulation is used in more than 70 of commercial roof construction as well as in many residential builds. When it comes to thermal efficiency and a wide range of building applications polyiso insulation is the 1 insulating material available today. More projects select polyiso roof insulation for both new and roof replacement systems than any other insulation product due to polyiso s numerous performance advantages which include.

Highlights the benefits of multi layering polyiso roof insulation with staggered joints to reduce thermal loss prevent moisture intrusion and maximize roof assembly durability.
