1. Good thermal stability
Gerui glass wool it has good high-temperature thermal stability, durability and resistance to high-temperature shrinkage; it can maintain long-term safety, stability and high efficiency within the recommended use temperature range and under normal working conditions.

2. Excellent long-lasting moisture resistance
Hydrophobicity refers to the ability of materials to resist water penetration. Gree glass wool has reached a hydrophobic rate of not less than 98%, which makes it have a more sustainable and stable heat preservation performance.

3. Heat insulation, sound absorption and noise reduction
Gerui glass wool slag ball has low content, long and thin fiber, which can well imprison the air, make it unable to flow, put an end to the convection heat transfer of air, greatly reduce the thermal conductivity of the product, and rapidly attenuate the transmission of sound, so it has excellent heat insulation, sound absorption and noise reduction effect.

4. Good fire performance
According to the European standard en13162:2 001 / AC: 2005 and GB 8624-1997, grey glass wool is a class a non combustible material.

5. No poison
Grey glass cotton is free of asbestos, mould and microorganism. Gree glass cotton is recognized as an environmental protection product by the national building materials testing center.
