Our premium rigid thermoset phenolic insulation delivers outstanding thermal performance with a thermal conductivity of just 0.019 W/mK. Paired with an integrated impact-resistant building board, this product ensures both superior insulation and a refined, durable finish. The closed-cell structure provides excellent thermal insulation properties whilst resisting air infiltration and moisture vapour transmission, protecting your structure from environmental challenges.
Installation is straightforward thanks to the product's user-friendly design, making it equally suitable for new builds and renovation projects. As a non-deleterious material, it poses no environmental harm. The manufacturing process uses a zero Ozone Depletion Potential (ODP) blowing agent with minimal Global Warming Potential (GWP), reflecting our commitment to sustainable building practices.
