ACFoam® CrossVent® Product Description
- Closed-cell 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.
- Combines nailable surface insulation and cross ventilating airspace.
- Available with minimum 19/32" CDX plywood.
- Atlas recommends a staggered double-layer application of ACFoam®-II and CrossVent®.
- Polyiso is the highest R-value per inch insulation in the industry. Excellent R-values reduce energy demands while maintaining compatibility with all types of roofing membranes and fire assemblies. See ASHRAE 90.1 Standards for Model Energy Code.
- CFC-, HCFC-, and HFC-free foam blowing technology with zero ozone depletion potential (ODP) and zero (negligible) global warming potential (GWP).
Recommended Uses
- Designed for use over sloped unventilated roof decks. Slopes must be appropriate for the type of roof system specified.
- The primary purpose is to provide a thermally efficient insulation with uniform cross venting that promotes air circulation required by many shingle manufacturers.
- Allows heat to dissipate while providing a nailable surface and efficient insulation in a one-step labor saving process.
Note: Ventilation design is solely the responsibility of the project designer. Designer should consider size of air space, ventilation capabilities of soffit and ridge vents, and length of run, among possible considerations. Atlas recommends a staggered double-layer of ACFoam®-II and CrossVent® for additional energy savings.
