12mm STS Construction Board (1200x800mm) (no more ply)

12mm STS Construction Board (1200 x 800mm) is a high-performance fibre cement construction board designed for use in wet, high-moisture, and heavy-duty environments. Commonly used as a NoMorePly alternative, this robust board provides a strong, water-resistant, and non-combustible base for tiling and surface finishes in both residential and commercial settings.

Manufactured from dense fibre cement, STS Construction Board is completely impervious to water and will not swell, rot, or degrade when exposed to moisture. The increased 12mm thickness delivers excellent rigidity and load-bearing strength, making it suitable for both wall and floor applications. The 1200 x 800mm board size offers a practical balance between coverage and handling, helping improve installation efficiency on site.
