Elevate ISOGARD HD Cover Board, 1/2 in. x 4 ft. x 8 ft. Polyiso High-Density Roof Board
Elevate ISOGARD HD is a 1/2 in. (12.7 mm) high-density, closed-cell polyisocyanurate foam cover board laminated both sides to mineral-coated fiberglass facers. It is offered in 4 ft. x 8 ft. and 4 ft. x 4 ft. gray panels, sold per piece. Use it over insulation or as a recovery board on refurbishment projects.
Key Features:
- High-density protection: The 12.7 mm PIR foam core laminated to mineral-coated fiberglass facers spreads load and protects insulation boards underneath.
- Impact resistant: Combines impact resistance and ease of installation in a single durable board.
- Top thermal value: Stated to have the highest thermal performance of any 12 mm rigid cover board.
- Wind uplift performance: Lays flat with superior wind uplift performance and requires fewer fasteners per board compared to 25 mm insulation boards.
- Lightweight handling: A single 1.22 m x 2.25 m board weighs only about 5 kg (roughly 11 lb), making placement easy.
- Fast installation: Easy to cut and handle around drains and penetrations, reducing installation time and labor costs.
- Recovery board use: Excellent choice for refurbishment projects as recovery board over an existing roofing system.

Expert Verdict — Reviewed by the SuperArbor Pro Desk
Choose ISOGARD HD when you need a thin cover board that adds impact resistance and thermal value without the weight of traditional wood fiber or gypsum boards. The 4 ft. x 8 ft. panel is the fastest option on large open fields, while the 4 ft. x 4 ft. size is easier to move on constrained roofs and detail work. Stagger board joints and follow the system manufacturer's fastening pattern to secure wind uplift performance.
Handle and cut boards with gloves and eye protection, use proper lifting technique on large panels, and follow the roof system manufacturer's fastening requirements.
Add Elevate ISOGARD HD cover board in 4 ft. x 8 ft. or 4 ft. x 4 ft. panels to your next commercial roof project.
