Glass wool blanket

Steel structure glass wool belongs to a category of glass fibre and is an artificial inorganic fibre. Quartz sand, limestone, dolomite and other natural ore are selected as the main raw materials, with soda ash, borax and other chemical raw materials used to fuse into glass fibre or glass wool. In the ablation or vapourised state, with the help of external force, the blown product is thrown into flocculent fine fibres. The fibres are three-dimensionally intersected, surrounded by each other, with many fine voids between. Therefore, glass wool insulation can be regarded as a porous material, with outstanding thermal insulation and sound absorption functions.

Glass wool blanket is a sheet product with a certain strength, achieved after curing. It continues to function and can withstand high or low temperature environments. It is mainly used for the construction of interior wall compartments, ceilings, ducts, sound absorption and noise reduction in computer rooms, and metal ceilings.

With the right protective equipment covering the skin, mouth and eyes, this material can be cut easily during construction. It is mainly used in the construction of indoor, noise reduction systems, transportation, refrigeration equipment, home appliances to reduce vibration, absorb sound and reduce noise.

Glass wool roll is manufactured using advanced production technology to process the board and roll felt products. It has a good ability to resist heat and reduce noise transfer. It is often used in boilers, reactors, tanks, pipes, high-temperature workshops and other high-temperature environments and thermal insulation materials in the power, chemical, and pharmaceutical industries.

When installing or unwinding, ensure that it is facing up. Lay the glass wool roll felt on the other side of the eaves. Leave the same 20 cm roll felt, and fix it on the outer-purlin with special clamps or double-sided tape. The rolls should be connected together by binding with a stapler on the veneer burr.

Each product has different shapes and specifications. People will consider different fields of application and the shape of the products produced. Some are curved, some are straight and so on. There are many specifications of glass wool board, and people often cut it according to their different needs. The construction process is very simple, and it is possible to cut into anything.

Some misconceptions about glass fibre or glass wool are that it contains asbestos and is bad for health and the environment. Whilst glass fibre does contain fine strands and sometimes borax, it does not contain asbestos. Glass fibre or wool does take significant energy in its manufacturing process, but as efficiency is increased the amount of related emission will also decrease and as an insulation product it acts to save energy through the loss of heat or coolth in use. Furthermore glass wool can be made from recycled glass and once made the wool is also 100% recyclable, though this will depend on contamination and purity.

Once installed, sealed and settled, glass fibre or wool is considered safe and resistant to fire. However when being rolled out, cut and installed the fibre can cause skin irritation and the dust should not be inhaled, therefore as when working with many materials on or off site, the correct protective equipment should be used to avoid any potential health hazards and professional guidance should be sought.
