Loadbearing Floor-Gemtree

Gemtree loadbearing floor board is made from high strength magnesium cement ,reinforced by fiberglass mesh and organic fiber which form a fiber network. in it to createa durable, dimensionally stable product.

4. Environmentally green: It is not toxic and non-radiation. It is environmentally friendly from raw materials, production,

2. It can be easily cut by using ordinary timber tool. For sake of durability tungsten carbide or diamond tipped blades

6. Sound insulation: Gemtreeboard provides excellent sound insulation. A single Gemtreeboard can achieve acoustic

3. For small holes a well-sharpened tungsten carbide masonry drill is recommended. Use a slow drill speed. Do not
