Wallboard XPS Type 3500 | Thermal Insulation Board

Product Description

Wallboard XPS Type 3500 is a high-performance thermal insulation board manufactured from extruded polystyrene (XPS). It is suitable for interior wall, external façade, and terrace applications. Thanks to its low thermal conductivity and high compressive strength, it provides long-lasting and effective thermal insulation performance.

The product complies with the European Union Construction Products Regulation (EU) No. 305/2011 with CE marking and is certified to be safe for human health, animal health, and environmental protection.
