The New Zealand building code specifies that all materials must have an effective lifespan of at least 50 years. So we offer a 50-year performance guarantee on both NOVAtherm and NOVAhush.

We guarantee that so long as the insulation is installed correctly, and remains adequately protected, it will perform as well as when new, at any stage up to the full 50 years.

Glues break down and are the weak point of many kinds of thermal and acoustic insulation. NOVAtherm and NOVAhush are heat welded, and contain no glues.
