(Puyallup, WA) – Insulfoam, a leading supplier of engineered insulation products, is pleased to announce the development of InsulFoam HD Composite, a continuous above deck insulation, for use on combustible decks. InsulFoam HD Composite consists of a closed-cell, lightweight, resilient expanded polystyrene (EPS) bonded to a high-density polyisocyanurate cover board. This product achieves a UL Class A rating on a combustible deck without gypsum or any other coverboard, and since it is continuous above the deck, it satisfies Title 24 requirements at a lower R value. InsulFoam HD Composite offers significant cost savings over other cover boards and traditional insulations, and is a very effective insulator – since it is installed above the combustible deck, there is no interruption due to joists. Its lightweight, factory-bonded panels make installation easy, it is compatible with all fully adhered or mechanically fastened EPDM, TPO, and PVC membranes, and it has a UL Class A rating for combustible and non-combustible decks. InsulFoam HD Composite will meet or exceed the requirements of ASTM C578 and is an excellent choice for new or retrofit applications where high thermal efficiency and maximum durability are necessary. It is available at Insulfoam locations across the country.
