Atlas ACFoam Recover Board CGF, 0.5 in. Polyiso Cover Board, 4 ft x 8 ft Panel
Atlas ACFoam Recover Board CGF is a 0.5-inch-thick polyisocyanurate cover board with inorganic coated glass facers, supplied as a 4 ft x 8 ft panel. Manufactured to ASTM C1289 Type II, Class 2 standards, it provides an improved substrate for roofing membranes in recover applications over existing roofs.
Key Features:
- Recover-ready substrate: Coated glass facers and polyiso core provide an improved substrate for roofing membrane in recover applications.
- Polyiso core: Closed-cell polyisocyanurate foam integrally bonded to inorganic coated glass facers.
- Standards compliant: Manufactured to ASTM C1289 Type II, Class 2, Grade 2 (20 psi) or Grade 3 (25 psi) and CAN/ULC-S704.
- Adhesive-efficient: Field testing confirms significantly more efficient use of solvent-based adhesives than organic-faced insulations.
- Zero ODP: Made with CFC-, HCFC- and HFC-free blowing technology with zero ozone depletion potential.
- Mold resistance validated: Validated by UL Environment as resistant to mold growth.
- Recycled content: Contains between 6.2% and 4.0% recycled materials by weight.

Coverage & How Much You Need:
One 4 ft x 8 ft panel covers 32 sq ft. Estimate the recover area in square feet and divide by 32, adding waste for cuts and laps.
Fit and Compatibility:
Used as a cover board over existing membranes or insulation in recover applications, in both adhered and mechanically attached systems. Membranes, adhesives and fasteners are sold separately; follow adhesive manufacturer application rates.

Expert Verdict — Reviewed by the SuperArbor Pro Desk
Recover boards save tear-off cost when the existing membrane is sound, and a polyiso recover board adds R-value at the same time. Verify the existing deck and membrane condition and local code limits on re-covers before proceeding. Stagger board joints and fit them tightly to keep the substrate smooth under the new membrane.
Confirm the existing roof structure can support the added load before installing a recover system, and use fall protection on all rooftop work.
Add Atlas ACFoam Recover Board CGF to your roof recover project for a smoother, better-insulated substrate.
