With the development of the construction industry, high-rise residential and high-rise will use glass wool as the wall filling material, sound absorption, insulation, noise reduction and energy saving for the building, but most owners are not familiar with glass wool this building insulation material, often consult the small series of its insulation performance, whether it is safe, there are no harmful substances.Today, Xiaobian will give you a multi-dimensional analysis of glass cotton fiber insulation materials.


Glass fiber insulation cotton is a kind of inorganic non-metallic material with excellent performance. It has the advantages of good insulation, strong heat resistance, good corrosion resistance and high mechanical strength, but the disadvantage is that it is brittle and has poor wear resistance.Glass fiber insulation cotton has the characteristics of low thermal conductivity, good sound-absorbing effect, long fiber and high tensile performance.Widely used in building air conditioning insulation system, decorative wall sound insulation, decorative ceiling, as well as chemical, electric power and other industries of equipment insulation.

Key points: heat preservation, heat insulation, sound absorption, fire prevention.

Features of glass fiber insulation cotton:

(1) good thermal break

According to the physical principle, the heat conductivity of the gas is small, and there are many air holes in the interior of the excellent heat breaking material.The glass fiber thermal insulation cotton produced by our factory has numerous small gas holes, and the fibers appear irregular arrangement, which is an excellent thermal insulation material with a thermal conductivity of 0.03W/cm.K.

(2) will not burn, with non-combustible, no deformation, no embrittlement, high temperature resistance up to 700 degrees, the combustion performance of A1 grade after testing.

(3) Do not contain any binder, without any smell, environmental protection and non-toxic.Compared with the traditional glass wool and rock wool products, it does not contain any binder, and will not emit any toxic and pungent smoke smell when exposed to high temperature.

(4) high insulation, glass fiber is the best insulation material.

(5) high corrosion resistance, glass fiber is not afraid of strong acid, long time will not reduce its functional characteristics.

(6) good recovery, glass fiber contains numerous fixed cavitation, excellent recovery.Not afraid of any impact vibration, tensile strength are more than 1.0kg.

(7) the hygroscopic rate is low, the hygroscopic rate is usually close to zero.
