Changle backer board is a practical base wall panel specifically designed for buildings where wall tiles or stone need to be applied. The unique embossing on the surface of the Changle backer panel provides a larger surface area for the panel, enhancing the adhesion between the panel and the tile adhesive, thereby enabling a stronger bond between the backer board and the wall tiles or stones.
Applications
Backer boards are suitable for use in damp areas such as kitchens, shower rooms, bathrooms, and laundry rooms.

Competitive Advantage
 |
1. A1 Non-combustible – Safety Starts at the Source The calcium silicate board meets the A1 fire rating standard – it does not burn and does not produce toxic smoke when exposed to fire. Even in high-temperature, open-flame environments, it effectively blocks the spread of fire, providing reliable protection for building safety. |
 |
2. High Strength – Stable and Durable The panel offers excellent mechanical strength with high impact and bending resistance, making it resistant to damage over long-term use. Combined with low shrinkage characteristics, it ensures good dimensional stability. Wall or partition systems remain flat, crack-free, and deformation-free. |
 |
3. Moisture & Mold Resistant – Unafraid of Humid Environments The panel does not absorb water, resists mold growth, and has strong freeze-thaw durability. Whether in basements, bathrooms, high-humidity coastal areas, or during rainy seasons, it maintains stable performance, completely solving the problems of traditional panels that swell or develop mold when exposed to moisture. |
 |
4. Formaldehyde-Free & Asbestos-Free – Green and Eco-Friendly The substrate is made of inorganic mineral components, containing no formaldehyde or asbestos, eliminating the release of harmful substances at the source. Odorless after installation, it is ready for immediate use, protecting users' respiratory health. It is especially suitable for spaces with strict environmental requirements such as hospitals, schools, and residences. |
