Carlisle SynTec SecurShield 2.5 in. x 4 ft x 4 ft Polyiso Roof Insulation Panel, Grade II (20 psi)
This Carlisle SynTec SecurShield panel is a 2.5 in. thick, 4 ft x 4 ft Grade-II polyiso roof insulation board with a closed-cell foam core bonded to premium coated-glass facers (CGF). Sold as a single panel covering 16 sq ft, it features ReadyFlash Technology for controlled adhesive flash-off and pairs with Carlisle single-ply membrane systems.
Key Features:
- ReadyFlash Facers: A dark CGF facer accelerates adhesive flash-off while the light CGF facer slows it, letting you control flash-off times.
- Fast Adhesive Work: The dark facer provides up to 2x faster flash-off on cooler days and up to 4x faster on warmer days.
- Premium Facer Performance: The coated-glass facers improve fire resistance, moisture resistance and dimensional stability.
- Wind Uplift Bond: A superior bond between facer and foam core enhances wind-uplift performance.
- Top R-Value Per Inch: SecurShield delivers the highest R-value per inch of commercially available insulation.
- Class A at 1 Inch: Achieves a UL Class A combustible deck rating at 1 in. thickness without a fire-rated slip sheet (max slope 1/2:12).
- 20 psi Grade II: Meets ASTM C1289-11, Type II, Class 2, Grade 2 (20 psi).

Expert Verdict — Reviewed by the SuperArbor Pro Desk
SecurShield's coated-glass facers make it a strong choice for adhered single-ply assemblies where dimensional stability and wind-uplift performance matter. The 4 ft x 4 ft size is easier to handle on congested or tapered roofs than 4x8 stock. Stage boards so you can choose facer side by weather: dark facer up on cool mornings, light facer up in heat, per Carlisle's adhesive flash-off guidance.
Foam boards are lightweight and can lift in wind before attachment; stack and secure panels promptly and follow manufacturer installation instructions and local code.
Order the Carlisle SynTec SecurShield 2.5 in. polyiso panel for precise adhesive control on your roof project.
