Product Description:


Glasswool blankets

1 Introduction

The glass woll blanket is applied for large laying area.Besides the character of thermal insurance, it also has the performances of shock absorption and acoustical isolation, especially for middle or low frequency sound. It can also cancel the noise and improve working environment. The glass wool blanket with aluminium foil surface has good capability of heat radiation protection.

2 Application

This material can be freely cut in construction according to the shape required, mainly used in room, noise-canceling system, transportation, refrigerators and household electric appliances for noise canceling. The blanket with alunimium foil is suitable for high temperature shops, control room, inner wall of the machine shops, room separating and inner liners.

3 Glass wool Blanket Specification

The glass wool blanket is applied for large laying area. Besides the charater of thermal insurance, it can also has the performances of shock absorption and acoustical isolation, especially for middle frequency sound. It also can cancel the noise and improve working environment.

Q:Centrifugal glass wool board is used to do what
Both in high temperature or low temperature environment can maintain a good thermal insulation sound-absorbing performance,
Q:Can glass wool be used for external wall insulation?
Yes, glass wool belongs to the category of glass fiber, which is a kind of man-made inorganic fiber. with good thermal insulation and sound-absorbing properties.
Q:whether the sound insulation is asbestos good or the glass wool good?
Because the main function is the fireproofing), sound absorption cotton belongs to asbestos, but match up with the installation (glass fiber cloth, and we in real life (in fact, we need the material with good sound insulation
Q:Glass wool and pef air conditioning insulation material, which one is better?
So many air-conditioning installation company will choose this new PEF thermal insulation cotton and rubber and plastic thermal insulation material. Generally many companies prefer to use PEF thermal insulation cotton for duct, and rubber and plastic thermal insulation material for water pipes. Productions can be selected according to each person's favor, but we can't only select the cheap products when selecting, and we should choose guaranteed green products.
Q:Why use reflective paper for pipeline package? Such as the caliduct in home is wrapped with a layer of reflective paper outside a layer of glass wool.
Reflective paper, also known as aluminum foil, which is used to prevent heat loss, for exampe, it will be put under the pipeline tto reflect heat upward before paving floor heating. While preventing heat loss.
Q:What are the advantages and disadvantages of glass fiber insulation cotton?
Glass fiber sound insulation cotton is difficult to use and destruction, due to weathering polluted the environment; it will be itching and allergic to skin if contact the skin; the long-term construction is harmful to the personal ; good water-absorbing quality, poor drainage, affecting sound absorption performance; no inorganic substance fiber, strong flame resistance and about 350 degrees deformation; good sound absorption performance; mild flavored.
Q:What is the density of glass wool?
Glass wool, a man-made inorganic fiber, belongs to a kind of glass fiber. It is a spongiform material made through fibration of melten glass. It is an inorganic fiber whose chemical components belong to glass, having good formability, low bulk density, low thermal conductivity, good thermal insulation and sound absorption, corrosion resistance and chemical stability. For centrifugal glass wool whose thickness exceed 5 cm and unit weight is 16Kg / m3, the sound absorption coefficient of low frequency125Hz is about 0.2, and that of middle and high frequency is close to 1. When the thickness continues to increase from 5cm, the low-frequency sound absorption coefficient also increase gradually. When the thickness is greater than 1m or more, 125Hz low frequency sound absorption coefficient will also be close to 1. Thicknesses of acoustic glass wools often used in architectural acoustics are 2.5cm, 5cm, 10cm, and unit weights are16,24,32,48,80,96,112kg / m3. centrifugal glass wool whose thickness is 5 cm and unit weight is 12-48kg / m3 is usually used.
Q:What is the thermal insulation material of glass wool?
It is a cotton-like material which has advantages of low thermal conductivity, chemical stability, good sound absorption. The glass wool is an inorganic fiber which has a excellent welding performance. Glass wool which is a man-made inorganic fiber fiberizes melten glass, it is a insulation material that has advantages of corrosion resistance, thermal insulation and small bulk density. I tell you that it belongs to glass in terms of chemical composition: The thermal insulation material, glass wool belongs to glass fiber.
Q:How much does centrifugal pan of glass wool need to invest? ?
More or less are both OK.
Q:What's the centrifugal glass wool?
Centrifugal glass wool is a kind of filiform material made by fibrillating and spraying thermosetting resin on the glass in melten state via centrifugal blowing process, which is then conducted thermosetting deep processing to make series products of a variety of uses. It has advantages like flame retardant, non-toxic, corrosion resistance, small unit weight, low heat conductivity coefficient, strong chemical stability, low moisture absorption rate, good hydrophobicity, etc., which is now recognized as the most superior material for heat conservation, thermal insulation and sound absorption with a very wide range of uses. The boards, carpets and pipes made of this material have been widely used for heat insulation and sound absorption in construction, chemical, electronics, electric power, metallurgy, energy, transportation and other areas, which have very significant effects.
