Patented ACFoam CrossVent insulation consists of a thermally efficient polyiso insulation board with 1.0", 1.5" or 2.0" vent spacer strips separating 7/16 in. APA/TECO rated OSB from the polyiso foam insulation to create a cross ventilating airspace. CrossVent combines the desirable benefits of a nailable surface and insulation with the addition of a cross ventilating airspace. CrossVent is made to order in 4´ x 8´ (1220mm x 2440mm) size panels and in nominal thicknesses of 2.5" to 6.5". Non-Standard vent spaces are available on special order.  Long Term Thermal Resistance (LTTR) Values & Thicknesses  Typical Physical Properties (Foam Portion)

Spec this Product   Net Free Area of Ventilation Per Linear Foot	RECOMMENDED USES ACFoam CrossVent has been designed for use over sloped unventilated roof decks. Slopes must be appropriate for the type of roof system specified. The primary purpose of CrossVent is to provide a thermally efficient insulation with uniform cross venting that promotes air circulation required by many shingle manufacturers. CrossVent allows heat to dissipate while providing a nailable surface and efficient insulation in a one-step labor saving process.

CrossVent should be installed with the 8 ft. dimension parallel to the eave and with the vent strips running up the slope of the roof. CrossVent shall be fastened directly through the venting strips in accordance with fastening patterns contained in the Atlas publication, Guide Details (Current Edition) for Nail Base, CrossVent, and CrossVent RB Insulation. Leave 1/8" spacing between OSB panels to allow for expansion and contraction and stagger end joints in successive panel rows.   Complete Instructions
STORAGE Factory applied packaging is intended only for protection during transit. When stored outdoors or on the job site, the insulation 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!
