Advantages of Cellular glass
1.Vermin, pest and botany proof
Cellular glass is inorganic no basis for nesting, breeding, also it's rat bite proof, plant roots cannot pierced this product.
2.Stable chemical property
China Foam Glass remains the chemical stability property of glass such as:oil-resisting, alkali-resisting, organic solvents resisting, and resist to almost all the acids. No destruction from aggressive mediums or atmospheres.
3.High compressive strength
