Elevate ISOGARD HD Composite Cover Board 120 psi, 1/2 in. x 4 ft. x 4 ft. Polyiso Roof Insulation Panel
Elevate ISOGARD HD Composite is a 120 psi high-density cover board combining a closed-cell polyiso foam core, a 1/2 in. (13 mm) high-density ISOGARD HD layer and coated glass facers. Each panel is sold as an individual 1/2 in. x 4 ft. x 4 ft. piece in gray. Use it as a cover board or recovery layer under most commercial roofing systems.
Key Features:
- High compressive strength: Rated at 120 psi, the board resists hail damage and foot traffic during and after installation.
- Composite construction: A closed-cell polyiso foam core is laminated to a 1/2 in. high-density ISOGARD HD board with coated glass facers.
- Thermal stability: Elevate polyiso insulation is stated to be the first product meeting both ASTM C1289 required and recommended thermal performance values.
- Reduced thermal drift: The ISOGARD formulation shows up to a 40% improvement in thermal drift compared with competitive polyiso products.
- Ozone-friendly blowing agent: ISOGARD Foam Technology uses an HCFC-free, ODP-free blowing agent; all Elevate polyiso uses EPA accepted blowing agents.
- Recycled material credit: Elevate polyiso insulations qualify under the Federal Procurement Regulation for Recycled Material.
- Broad system fit: Suitable for use with most commercial roofing systems.

Coverage & How Much You Need:
Each 4 ft. x 4 ft. panel covers 16 sq. ft. of roof area. Divide total roof square footage by 16 to estimate panel count, allowing for cuts around penetrations and layout waste.
Fit and Compatibility:
Designed for use with most commercial roofing systems as a high-density cover board over insulation or as a component in an Elevate polyiso roof assembly. Membrane, adhesives and fasteners are sold separately.

Expert Verdict — Reviewed by the SuperArbor Pro Desk
Specify the composite version when you need both thermal value and a durable walking/hail-resistant surface in one board, such as over rigid insulation on a commercial low-slope roof. Because the high-density layer is only on one side, orient the HD board face up under the membrane. Cut panels with a fine-tooth saw or insulation knife around drains and penetrations, and stagger joints between layers to reduce thermal bridging.
Wear gloves, eye protection and appropriate footwear when cutting and handling rigid foam boards, and follow the roofing system manufacturer's fastening and fire-safety requirements.
