Carlisle SynTec SecurShield 3 in. x 4 ft x 8 ft Polyiso Roof Insulation Panel, Grade-II 20 psi
This is a Carlisle SynTec SecurShield Grade-II (20 psi) polyisocyanurate roof insulation panel, 3 in. thick and 4 ft x 8 ft, sold as one piece. The closed-cell foam core is bonded to premium coated-glass facers, and ReadyFlash technology provides a dark facer on one side and a light facer on the other to control membrane adhesive flash-off. Pair it under Carlisle single-ply membrane systems.
Key Features:
- ReadyFlash Technology: A dark coated-glass facer on one side and a light facer on the other let the contractor speed up or slow down membrane adhesive flash-off times.
- High R-Value: Polyiso delivers the highest R-value per inch of commercially available roof insulation.
- 20 psi Compressive Strength: This Grade-II panel is rated at 20 psi compressive strength for commercial roof insulation use.
- Fire Performance: SecurShield achieves a UL Class A combustible deck rating at 1 in. thickness without a fire-rated slip sheet or gypsum coverboard, at maximum roof slope of 1/2:12.
- Superior Facer Bond: The premium coated-glass facer has a superior bond to the foam core that enhances wind-uplift performance, moisture resistance and dimensional stability.
- Faster Coverage: The 4 ft x 8 ft format covers 32 sq ft per panel, twice the area of a 4 ft x 4 ft board, speeding installation.

Expert Verdict — Reviewed by the SuperArbor Pro Desk
The 3 in. Grade-II 20 psi SecurShield panel is a workhorse thickness for commercial assemblies targeting higher R-values, and the 4 ft x 8 ft format reduces joint count versus 4x4 boards. Use the dark facer toward the membrane on cooler days to speed adhesive flash-off up to 2x. Install per Carlisle specifications with compatible fasteners or adhesives and confirm code requirements for slope and uplift.
Follow Carlisle installation specifications and local building and fire codes, and use appropriate fall protection when working on low-slope roofs.
Order the Carlisle SynTec SecurShield 3 in. 4 ft x 8 ft polyiso insulation panel for high R-value commercial roof insulation.
