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
cellular glass has high compressive strength even with long-term loads due to its cell geometry
4.Dimensionally stable
Cellular glass has low expansion coefficient, comparable to steel and concrete. It neither shrinks nor swells under temperature cycling, no warping, buckling or creep.
5.Easy to Process
Cellular glass is easy to cut, shape, install at site, and it can be perfabricated according to design. With simple tools like saw blade or hand saw, it can be cut to any desired shape.
