Claims are easy. So we film the tests, publish the numbers and put the guarantee in writing. Then we send you a sample so you can try to prove us wrong.

Independent of how it looks, here’s how it measures.
No connected air paths in the closed-cell structure, so there’s no route in, even at a drilled hole or cut edge.

Euroclass B-s2,d0, tested to EN 13501-1.
Fifteen years of production, not one panel back with water inside it. We put a lifetime waterproof guarantee in writing in 2023. The boards had already earned it.
