Resista AK 120mm insulation
Firestone RESISTA AK insulation board
120MM ( 600mm x 1200mm) roof insulation board
Firestone RESISTA AK 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.
Is this comparable to the eco roll?1 answer
Hi Gordon, thank you for reaching out with your question.
The Eco roll ( https://www.permaroofstore.co.uk/default/permavent-eco-1-0m-x-50m-roll.html ) is a breather membrane, used to help reduce condensation in all types of roofing. Although it can help to reduce heat loss, it is not a substitute for the insulating properties of the Resista AK insulation board.
We hope this helps, thanks for getting in touch. If you have any further questions, please don’t hesitate to call one of the team on 01773 441947 or for a quick query, use the live chat facility.
