Rock wool fireproof sandwich panel is a new type of board developed on the basis of pu sandwich panel to improve the fireproof grade of the board. On the basis of ensuring the strength and thermal insulation of the original polyurethane board, the fireproof grade of the board reaches Class A non-combustible, which greatly broadens its scope of use, and the formed board has the characteristics of fireproof, thermal insulation, and environmental protection.
The core material of the Rock wool fireproof sandwich panel uses high-quality natural rocks such as basalt and gabbro as the main raw materials. It is an artificial inorganic fiber made through strictly controlled processes such as high-temperature melting. It is a real rock wool with low slag and dust content and no water absorption.
Advantages of rock wool products：
1. Fireproof performance: The core material of rock wool is Class A non-combustible material with a melting temperature of more than 1000℃, which can effectively prevent the spread of flames and minimize fire losses.
2. Insulation and energy saving: Rock wool has a low thermal conductivity (≤0.043w/m.k) and good thermal insulation performance.
3. Good sound insulation: excellent sound insulation and noise reduction performance, sound insulation ≥ 30dB, effectively reducing the interference of external noise.
4. Water tightness/air tightness: The interface of the board adopts mosaic overlap, which greatly improves its waterproof and air tightness, and the rock wool has a high water repellency.
5. Strong and durable: The bulk density of the rock wool core material used by our company is 120kg/m2 (bulk density can be customized), which well guarantees the strength of the board.
