Why Choose Rock Wool Sandwich Panels?
Rock wool sandwich panels are widely used in ceilings and partitions of steel structure workshops, roofs of simple mobile homes, walls, and air clean rooms.Rock wool sandwich panels can generally be customized according to customer requirements. Rock wool sandwich panels are the most excellent in fire resistance of a series of sandwich panels.
1. Excellent fire resistance: The raw materials, production process and formula used for the polyurethane double-sided rock wool sandwich panel make it have good fire resistance. Tests show that it has a fire resistance in excess of 1000 ° C. The polyurethane double-sided sealed rock wool sandwich panel has passed the test of Italian authoritative testing agency GIOROANO SPA. According to the standards of the International Organization for Standardization (ISO), British BS and German DIN, the rock wool sandwich panel meets the fire protection standard MI 14/09 / 61 Letter 91 and DM 30/11/83. The test results are as follows: 50mm thickness polyurethane double-sided sealed rock wool sandwich panel REI 30, 80mm thickness polyurethane double-sided sealed rock wool sandwich panel REI 60, 100mm thick polyurethane double-sided sealed rock wool sandwich panel REI 120.
2. Good thermal insulation: The thermal insulation of polyurethane double-sided sealed rock wool sandwich panels is based on the thermal conductivity of rock wool λ = 0.043 W / m2 K, and is calculated based on the thickness of the rock wool core material.
3. Sound insulation and sound absorption effect is remarkable: Polyurethane double-sided sealed rock wool sandwich panel has a significant reduction effect on noise transmission, and is particularly suitable for places where a designated flight passes. In addition, after the use of rock wool roofing panels, the indoor noise caused by the impact of rain and hail on the roof steel plate of the building is also significantly reduced. Through testing, according to the ISO 717/82 and UNI 8270/7 standards, a sandwich panel with a density of 120 kg / m3 rock wool is used as the core material, and the sound insulation effect can reach RW = 29 ~ 30 dB. Rock wool sandwich panel also has excellent sound absorption effect, it can absorb sound in a wide frequency range. According to the ISO 354/85 standard, the sound absorption performance of rock wool sandwich panels reaches DELTA LA = 15.7 dB (A).
