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. 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.

Technical Data


















3. Application

It is mainly used for the partition wall in the high-grade building, such as ceiling, air conduit and inner wall for thermal insurance, machine shops for noise absorption and metal ceiling for control of moisture.High density glass wool blanket with laminated facing can be used for air conditioning duct system.

4. Image and Package

Normal packing: each roll is wrapped with vacuum plastic bag and then in PE woven bag. Special required package like PE BAG and PE SHRINGED BAG can be made with additional charge.

Q:Are foam glass and glass wool the same?
Q:Do you have any recommendation about the glue used to adhere the glass wool to glass fiber felt? Thank you.
I also want to know the reason why glass wool and glass fiber felt are not tightly packed.
Q:what is the specification of glass wool sound-absorbing board?
General specifications include 600 * 600600 * 500 * 1200-1200/12000300/400 mm thickness is usually 14 to 22 mm. . Glass wool belongs to a category of glass fiber, and is a kind of man-made inorganic fiber. Glass wool is a kind of spongiform material shaped by making melten glass fibering, it's chemical content belongs to glass and is a kind of inorganic fiber. It has good molding, small bulk density, low thermal conductivity, good thermal insulation and heat insulation, good sound absorption, corrosion resistance and stable chemical performance. Centrifugal glass wool belongs to porous materials and has good sound absorption performance. Centrifugal glass wool can sound-absorbing reason is not due to the rough surface, but because of there exist a large number of internal and external connected tiny pore and holes. When sound waves enter on the centrifugal glass wool, sound waves can follow the internal pore into inner material, cause the vibration of air molecules in space. Because of the friction of air viscous resistance and air molecules and pore wall, sound energy is wore down after being transferred into heat energy.
Q:What does the thermal insulation test of glass rock wool include?
Appearance, dimensional deviation(length, width, height), shot content, average diameter of fibers, flatness deviation, right-angle deviation, water absorption coefficient, hydrophobic rate, short-term water absorption, tensile strength perpendicular to the surface, compression strength, heat conductivity coefficient, dimensional stability, noise reduction coefficient, acidity coefficient, vapor diffusion resistance factor, long-term water absorption, combustion performance. These are testing programs of rock wool thermal insulation boards. The raw materials and performance of which are different from that of glass wool. In addition to the different areas, the required testing programs are different too. My answer is for reference only.
Q:how to choose external wall insulation materials for glass wool?
Glass wool insulation materials insulate medium and low temperature. it belongs to A level fireproof materials and non-combustible. the use temperature of glass wool insulation material is-120 ℃ -400 ℃, used in construction, petrochemical, power, metallurgy and other fields of thermal insulation, sound absorption. Glass wool glass fibers is a man-made mineral fiber, a kind of glass fiber. Glass wool is molten glass that undergoes fibration process, cotton-like material. it is a good shaped inorganic fiber with small volume density, low thermal conductivity, thermal insulation property, sound-absorbing properties, corrosion resistance , chemical stability.
Q:What is the difference between red glass wool and yellow glass wool in terms of technical parameters?
Thermal insulation properties: Red yellow glass VS Yellow glass wool. Thermal conductivity (K): below 0.039 VS over 0.044; Resilience: good VS poor. Distribution: even VS uneven. Irritation: non-irritating VS irritating and cause itching of skin. Dust: without dust VS with dust. Shot content: zero VS non-zero. Red glass wool is an environmental-friendly material.
Q:How to construct when apply rock wool board to glass curtain wall?
Base treatment--Coat interfacial agent on both sides of rock wool boards and the side - hang vertical line and flip the controlling line- Paste rock wool boards with the adhesive- Plastering the first rendering coat mortar--Pressing the alkali-resistant glass fiber mesh in it-- Anchoring rendering coat mortar composite alkali-resistant glass fiber mesh--Plastering the second rendering coat mortar and press alkali-resistant glass fiber mesh into it-- Plastering the third rendering coat mortar
Q:how to get rid of the fur of the glass wool on the hand?
Stick it out with tape medical tape, rheumatism paste tape, and scotch tape.
Q:Whether the rock wool is belong to the glass wool product or not.
the manmade inorganic fiber is made by the high-speed centrifugation equipment. it molding is good. the different rock wool thermal insulation products has different requirements, and it can be made into different specification and the material of the cotton-shaped is the inorganic substance fiber with stable chemical performance. Glass wool is melten glass fibrosis, it is corrosion resistance, and man-made inorganic fiber, while adding a special binder and dust laying oil, low bulk density, good sound absorption, thermal insulation, low thermal conductivity. Glass wool belongs to a category in glass fiber, chemical composition belongs to glass, melting in high temperature! the specific defination is in the following rock wool is taken the natural basalt as the main raw material. the two names are different but the thermal insulating and refractory material performance is nearly the same.
Q:How about the thermal insulation performance of glass wool?
The features of glass wool mainly include light weight, easy installation, high thermal insulation efficiency, low hygroscopicity, and strong vibration resistance. Fibers of raw materials of glass wool are relatively even in terms of length and thickness, they are closely intertwined during processing procedures. The interwoven structure and its heat conduction are at a right angle, which can effectively retain heat. It operates simply during installation and use, simple common tools are needed to cut. Meanwhile, there will not be disjointed or stretched in use. There are a lot of tiny air voids in the glass wool, thus the physical property is also relatively stable. It is commonly used in various heating, ventilation, tank, air-conditioning adjustment, the performance of which is significant. Of course, the glass wool can also be customized, we can make glass wool with special specification according to your requirements. Using glass wool as thermal insulation materials has been a very long time, and we found that in a quite a long comparison test, the thermal insulation performance is fairly stable, which will not lead to accidents in use.
