Advantages of lar glass
1.Vermin, pest and botany proof
lar 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 atmosres.
3.High compressive strength
lar glass has high compressive strength even with long-term loads due to its geometry
