rock wool sandwich panel with PU sealing

Sandwich board products are formed by two layers of metal panel (or other material panel) and directly in the panel to ask foaming, curing molding polymer heat insulation core. These sandwich panels are easy to install, lightweight and efficient. The filling system also uses a closed bubble molecular structure that prevents condensation of water vapor. The forming of the outer steel plate takes full account of the structure and strength requirements, and takes into account the beauty, the inner surface layer is formed as a flat plate to meet various needs.

Advantages of new model rock wool:

1.Non inflammability and Level A fireproof performance
2.Excellent performance in thermal insulation
3.Biodegradable and environment-friendly
4.Hydrophobic property and high ageing resistance
5.Sound absorption and noise reduction
6.High acidity coefficient can greatly reduce the corrosive action on metals.

Note:usually the material with low thermal conductivity is regarded as thermal insulation material ( it is stipulated that all the materials with a thermal conductivity no more than 0.12W/(m.K) when the temperature is lower than 350℃ called thermal insulation materials in national standard.),and the materials with a thermal conductivity less than 0.05w/m.K is named high-efficient thermal insulation material.

The application of exclusive fireproof PIR side sealing technology increases the air-tightness and water-tightness in lap-joints,thus preventing the cold bridge from happening,and at the same time,the separation of steel sheets from core materials is avoided while transportation and installation.
ROCK WOOL Sandwich panels can suffer from high temperature of 600℃，it won’t burn when the flame
extinguished.Also our products have a good performance of water resistant and scratches prevention.Welcome to consult us. We supply the service of customized
