Rock wool board, as a specialized rock wool for metal faced sandwich board, is widely used in sandwich board rock wool core material, decorative integrated board cotton core material, etc. After being cut and flipped,it has high tensile and compression resistance. At the same time, it has the properties of thermal insulation, fire prevention, sound absorption and noise reduction,etc., which plays a decisive role in improving the overall quality of the color steel sandwich board. With the development of the colorsteel industry, product requi rements are also constantly improvingto ensure that product performance meets and exceeds industry standards.
1.Rockwool is made of natural rock and is a Class A non-combustible fireproof material. Its melting temperature is over 1000ºC,
which can effectively slow down the spread of fire.
2.The thermal conductivity is low and the thermal insulation effect is significant.
3.Greatly reducing the reflection and propagation of sound waves and providing a beneficial environment without interference for work and life.
4.The open porous fiber structure makes rockwool have excellent air permeability and moisture-drying function, which allows
water vapor to pass freely, effectively reducing condensation and building mildew.
5.The rock wool for external wall insulation, high-strength rock wool board for roofs and composite board with rock wool have high
tensile strength and compression strength, which can effectively resist the alternating effects of positive and negative wind
pressures and have strong impact resistance.
6.Rock wool is frost-resistant, freeze-thaw resistant, and UV-resistant. It does not produce thermal expansion andcontraction due
to temperature differences in the four seasons. It can be used in extreme climates without being affected by other combined
materials.
7.Water-repellent and moisture proof.
8.The energy saved by rock wool in use is more than 100 times the energy consumed in its production, transportation and
recycling.
9.Safe and environmental protection.
10.Easy to carry and cut. It can be completed with a scissors.
