Firestone RESISTA AK insulation board

50MM (600mm x 1200mm) Polyiso (PIR) roof insulation board

consists of a closed-cell polyiso foam core laminated on both sides to a gastight multi-layered aluminium complex. The foam technology uses a HCFC-free blowing agent with a GWP (Global Warming Potential) of less than 5 and zero ODP (Ozone Depletion Potential). RESISTA AK is suitable for use on adhered, ballasted and mechanically fastened Firestone single-ply roofing systems (UltraPly™ TPO, RubberGard™ EPDM and RubberCover™ EPDM). RESISTA AK provides outstanding and stable thermal resistance, dimensional stability and compressive strength, which translates into a complete flat roof solution with long lasting superior performance.

      Hi Jason, thanks for your great question.

      Both Resista AK board sizes offer an outstanding life expectancy and deliver value for money. The 50mm board offers an RD-Value (m2.K/W) of 2.15 and the 120mm board ( ) offers a comparative value of 5.20. It really does depend on your project.
