Rock wool color steel tile fire function excellent insulation good heat insulation sound absorption effect is significant. Rock wool sandwich board gives full play to the common function of rock wool core material, and has significant effect in fire prevention, heat insulation, sound absorption and sound insulation. Excellent fire prevention function, rock wool sandwich board

The raw materials used.

Production technology and formula, so that it has a good fire protection function. Experiments show that it has a fire resistance beyond 1000°C. The rock wool sandwich board has been tested by the authority inspection arrangement. According to the world standard arrangement, the rock wool sandwich board is satisfied with the fire code.I14/09/61

Letter No. 91 and request from D.M.30/11/83.

The experimental results are as follows: 50mm thick rock wool sandwich board REL30 80mm thick rock wool sandwich board REL120 has good thermal insulation performance: the thermal insulation function of the rock wool sandwich board is calculated based on the thermal conductivity of rock wool =0.043W/m.K, and the corresponding share of the core thickness of rock wool is calculated.

Sound absorption and heat insulation effect is significant, sound insulation: rock wool sandwich board has a significant reduction effect on noise transmission, especially suitable for the designated flight over the local. In addition, after the rock wool roofing board is selected, rainwater and hail impact on the roof steel plate of the building and cause indoor movement, which is also significantly weakened. According to ISO717/82 and UNI 8270/7, the density is 120kg/m.
