STS 12mm Insulation Board is a rigid extruded polystyrene (XPS) tile backing board designed to provide a stable, moisture-resistant base for tiling and wall applications.
Manufactured from high density XPS foam with reinforced surfaces, this board offers a lightweight yet strong substrate suitable for bathrooms, kitchens, and wet room environments. It provides both thermal insulation and a secure fixing surface for tiles, helping improve overall installation performance.
The water-resistant core prevents moisture absorption, making it suitable for areas exposed to humidity and direct water contact. The board can be easily cut and installed, supporting efficient on-site handling.
Compared to traditional plasterboard or cement boards, XPS tile backing boards offer a combination of insulation, water resistance, and ease of installation. This helps reduce preparation time while improving long-term durability in wet areas.
This insulation board provides a reliable and practical solution for preparing surfaces prior to tiling while improving thermal performance and moisture resistance.
