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. |

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.
