Inverted roof insulation boards.

Benefits of inverted roofs. Protherm sd upstand insulation board has a zero ozone depletion potential odp a global warming potential gwp of less than 5 and an a rating in accordance with the green guide to specification. This makes it the only material suitable and approved for inverted roof applications. Inverted roofs have their waterproofing layer beneath the insulation instead of above it as in other forms of roofing.

Exceptional dimensional stability and rated for extreme hail rockwool stone wool insulation roof boards have meet both the fm severe hail and the ul 2218a standard for impact resistance.
