Building envelopes, by definition, ensure an effective boundary between the interior of a building and the external environment, for example, exterior walls, foundations, windows and doors. This requires materials that can be easily customised, with precise dimensions, and can withstand varying processing times and temperatures, while also being robust and capable of delivering long-term performance. With a proven track record since 2005, our PET-based foam solutions offer minimal density fluctuations for process stability and excellent thermal and dimensional stability for consistent production. Made from 100 percent recycled material, it combines high impact resistance with full recyclability, and superior resistance to corrosion, rot, and degradation. Explore all our solutions below.
