Rock wool and glass wool, as common energy-saving insulation materials, are widely used in modern buildings, and have significant social, economic and environmental benefits, and have a broad market prospect.

New energy-saving materials are widely used in modern buildings, which have significant social, economic and environmental benefits, and have a broad market prospect.

Common energy-saving insulation materials on the market include rock wool, glass wool and other insulation products.

Rock wool:

Rock wool is an inorganic artificial fiber made of basalt or diabase as the main raw material and melted at high temperature. Rock wool products mainly include: rock wool boards, rock wool felts, barbed wire rock wool felts, rock wool strips, and rock wool pipes.

Rock wool products have good thermal insulation, heat insulation, sound absorption, non-combustibility and good chemical stability. Rock wool is mostly used in building exterior walls. There are three types of thermal insulation: internal thermal insulation, intermediate core thermal insulation, and external thermal insulation.


Glass wool:

Glass wool uses silica sand, limestone, fluorite and other minerals as its main raw materials. After melting, it uses the flame method, centrifugation method or high-pressure gas injection method to make molten glass liquid into inorganic fibers.

Glass wool products have good thermal insulation, heat insulation, sound absorption, non-combustibility, corrosion resistance and other properties. They are widely used in the insulation, sound insulation and sound absorption of houses, pipes, storage tanks, boilers, aircraft, ships and other related parts.

The thermal insulation effect of thermal insulation materials is mostly determined by the thermal conductivity of the material itself. The material's thermal conductivity  is related to material composition, material structure, material apparent density, material pore size, material characteristics, material humidity, moisture content, and the temperature of the material. In short, the smaller the thermal conductivity of the material, the better the thermal insulation of the material.

With the development of today's living standards and the improvement of building construction, people's demand for renewable energy is increasing. The development and use of new, energy-saving, environmentally-friendly, and renewable energy has become a must to achieve healthy economic development and energy recycling road.
