As a kind of modern building material, rock wool sandwich board has been widely used in the construction field for its excellent performance. As one of the key characteristics, its fire resistance is very important to ensure the safety of buildings. This article will discuss the fire resistance limit of rock wool sandwich board and related knowledge to help everyone have a more comprehensive understanding.

Fire resistance limit refers to the limit that the material can withstand external fire damage and maintain its original performance. For fireproof building materials such as rock wool sandwich composite panels, fire resistance is not only an indicator, but also an important basis for evaluating its applicability and safety. Its fire resistance limit according to the density, thickness and other factors, generally in 1-3 hours or so, in general, the thicker the plate, the higher the density of rock wool, the better its fire resistance.

As the industry's leading supplier of metal enclosure products, the rock wool sandwich panels produced by WISKIND, such as: COLORPOD ®, COLORGOLD ®, COLORGEM ®, COLORCURTAIN ®, structural rock wool sandwich panels and other products, are made of domestic high-quality color coated panels and high-density hydrophobic rock wool, with excellent fire resistance.

Under the fire resistance limit of materials specified in GB/T 9978 standard, the fire resistance limit of Master Rockwool Sandwich Panel can reach 3 hours, which is at the leading level in the industry. It can effectively prevent the spread of fire in the event of a fire, and will not release toxic gases during the fire, creating more escape time and protecting the safety of the building structure.
