The Firestone RESISTA AK insulation board consists of a closed-cell polyisocyanurate (PIR) foam core laminated on both sides to a gastight multi-layered aluminium complex. It is suitable for use on adhered (no torch), ballasted and mechanically fastened single-ply roofing systems.
RESISTA AK provides outstanding and stable thermal resistance, dimensional stability and compressive strength, which translates into a long lasting superior performance.
Superior thermal resistance
The board’s foam formulation, combined with a multilayer aluminium complex facer, results in outstanding thermal performance.
Wind uplift performance
Foam and facer have been designed for optimum adhesion in case of a fully adhered membrane application. Branded facer should always be facing upwards.
High compressive strength
≥ 150 kPa
Good reaction to fire
Boards do not smolder, melt or drip and they do not promote fire propagation.
No sharp edges.
Easy to transport, hoist and install. Helps reducing the roof total weight and reduces installation time and costs.
When installed correctly, it will last for the lifetime of the building.
The foam technology uses a HCFC-free blowing agent with a low GWP (Global Warming Potential) and zero ODP (Ozone Depletion Potential).
- Shrink-wrap packaging provides a protective covering to all sides of the bundle.
- Bundles are approx. 500 mm high, combined into stacks of 2500 mm to 2650 mm high.
- Spacers keep the stacks elevated of the floor for dry storage and easy handling.
