Polyiso Roof Sheathing

Acfoam recover board is manufactured and tested for use in recover applications acfoam recover board is a rigid polyiso roof insulation faced with inorganic coated polymer bonded glass fiber mat facers.

Polyiso roof sheathing.

Polyiso is most commonly used as a continuous insulation for roofs and walls and as a protective roof cover board. Energyguard polyiso insulated sheathing is made of bilaminate aluminum and kraft facers bonded to a core of polyiso foam. Hailgard insulation is an insulation panel consisting of a polyiso foam core laminated to a 7 16 oriented strand board osb on one side and a black glass reinforced mat facer on the other side. It keeps the roof sheathing above the dew point during the winter preventing moisture accumulation in the sheathing.

Fm approved subject to the conditions of approval as a roof insulation when installed as shown in the current edition of the factory mutual research approvals guide. Polyiso is a versatile high performance insulation solution that is suitable for a multitude of applications. Excellent lttr value compared to any other fm class 1 rated products of equivalent thickness. The polyiso performs an essential function.

If instead you are considering a vented roof assembly then the polyiso would be unnecessary. Benefits of energyguard polyiso roof insulation include. Energyguard polyiso insulated sheathing is a great option for helping to reduce energy costs due to its high r value per inch. Recover board is a thermally efficient and dimensionally stable recover board solution.
