ACFoam Nail Base Insulation is a thermally efficient polyiso insulation board bonded to 7/16" APA/TECO rated OSB on the top side and with a glass fiber reinforced felt facer on the bottom. ACFoam Nail Base Insulation provides the desirable benefits of both a nailable surface and insulation making installation an easy one-step labor saving process. This product is made to order in 4´ x 8´ (1220mm x 2440mm) panels and in nominal thicknesses of 1.5" to 4.5". Other thicknesses are available on special order. Click Here for Guide Details & Fastening Patterns In 1998, years ahead of the Environmental Protection Agency timetable for eliminating HCFCs (hydrochlorofluorocarbons), Atlas introduced a line of ACFoam Products that are environmentally sensitive and available for virtually every type of construction system. Through a patented hydrocarbon blowing technology called ACUltra, Atlas began the phaseout of HCFCs in the manufacturing of foam insulation and anticipates the complete removal of HCFCs from all Atlas foam products within the next year.  Long Term Thermal Resistance (LTTR) Values & Thicknesses  Typical Physical Properties (Foam Portion)

Spec this Product	RECOMMENDED USES ACFoam Nail Base Insulation is typically specified for use over solid wood and metal decks having a slope of a minimum 1/4" per foot. Slopes must be appropriate for the type of roof system specified. The OSB provides an excellent base for nailing non-asphaltic shingles. It is especially efficient as a component over cathedral ceilings in log homes, conventional housing, churches and athletic auditoriums. Additionally, ACFoam Nail Base Insulation may be installed under metal roof systems and over metal decks minimum 22 gauge or heavier. This product should be used only in strict accordance with Atlas recommended uses and application instructions. Atlas recommends the use of vapor retarder for all projects except in extreme cooling climates. However, determining the need for and location of the vapor retarder remains solely the responsibility of the architect, engineer or design professional.

When stored outdoors or on the job site, packages should be stacked on pallets at least four inches above ground level and completely covered with a weatherproof covering such as a tarpaulin. The temporary factory-applied packaging should be slit or removed to prevent accumulation of condensation. Roof insulation which has become wet or damaged should be removed and replaced with solid, dry insulation. Warning!
