Product Description:

1.  Glasswool Description

Glasswool board is the unearthly sound absorbing and warm keeping material. It has been widely applied for heat insulation of house wall, compartment; temperature keeping of computer rooms, refrigerator; denoise of power plants and pump rooms; adjustment of Hi-fi etc.

This special cell structure means that the sheet doe’s not conduct heat. When you lay XPS boards as an underlay any heat from your room or floor will be reflected back towards the floor surface. As you will not be wasting heat through your floor you will utilize your energy in an effective manner and thereby lower your energy consumption and carbon footprint.

 

2. Main Features

1. Excellent thermal insulation

2. High compressive strength of excellence

3. High-quality water-repellent, moisture resistance

4. Energy saving and environmental protection

Q:How about the quoted price of glass wool board of 96kg?
Quoted market price. 1, Sheng Ming glass wool board. Weight: 96kg. The texture is glass fiber. Price: 300 RMB yuan. 2, Sheng Ze glass wool board whose texture is glass fiber. Specifications: 1.2mX2mX50mm. Price: 129 RMB yuan. 3, Li Jing glass wool board. Specifications: 2420 * 1220 * 25mm. The texture is glass fiber. Price: More than 159 RMB yuan.
Q:Which kind of soundproof cotton is the best for decorative gypsum board partition ? Mineral rock wool or glass wool?
The upstairs answer is wrong. rock wool is made of basalt through melting and spining, rather than asbestos. Asbestos and rock wool are two different things. Please check soundproof walls. From the aspect of soundproof effect, it is better to combine rock wool and glass wool, with the former insulating low frequency and the latter insulating high frequency. Unit weight should be above 80k. In terms of construction, they are similar. Rock wool may be more difficult for construction workers but it is cheaper than glass wool.
Q:What are the disadvantages of glass wool? What are the technical limitations in application?
Each insulation material has its own advantages and disadvantages. Let's take glass wool and rock wool as an example. Glass wool is less irritating to the workers' skin than than rock wool is in construction workers, but we can not say that the glass wool is not irritating at all. Besides, the melting point of glass wool and rock wool is different. The thermal insulation effect of glass wool is better than rock wool when they have the same bulk density and thickness.
Q:What is the difference between rock wool and glass wool?
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:Who know the construction technology of glass wool?
1, The construction condition. 1.1, The substrate must be dry and be passed acceptance inspection. 1.2, The construction site should be granted with no more than five grade of wind force during construction. 1.3, Effective measures should be taken during construction in rainy days to prevent glass wool from being wetted by rainwater. 2, the main construction tools: wllpaper knife, electric screwdriver and fe, electric screwdriver and 2m guiding rule. 3, Construction process. 4. Construction points. 4.1, Construction preparation: 4.1.1, Material preparation: Prepare the detailed supply planned order of materials according to the drawings and projects condition. All materials approved into the site must be qualified products, complying with the relevant regulatory requirements nationally, industrially and locally. 4.1.2 Construction machinery: All machinery must be tested to ensure their good performance. 4.1.3, Personnel preparation: Technical personnel must be provided with technical training and technical disclosure. 4.1.4, Technical preparation: It needs to know well the drawings, prepare the relevant portfolios and quality acceptance criteria. 4.2 Installation of glass wool. 4.2.1 Select expansion insulation nails with corresponding length according to the thickness of glass wool, and make glass wool into sample plate based on the field condition before installing it. 4.2.3, Using insulation nails screw to pierce glass wool to install them into the wall according to the position of insulation nails on the facade of wall, which requires that glass wool should be assembled tightly and neatly without folds. 4.2.4, All seams should be cling to with each other with the gap of no more 3mm, and finally all seams should be sealed with adhesive tape.
Q:To reach better sound absorption effect, which should be filled in the keel, glass wool felt / board or polyester fiber cotton felt / board ?
Both materials are inappropriate to used for noise insulation, for glass wool and polyester fiber cotton are sound-absorbing materials. Neither is good for sound insulation. They can be used to prevent echo formation in the room, and their function is to reduce the reflection of sound indoors.
Q:Glass wool 159 * 70 What does it mean
70 km diameter 159mm.
Q:Which has better effect of thermal insulation, glass wool or rock wool ?
They are basically the same, but glass wool is more eco-friendly, with smaller loss.
Q:What is the difference between the glass fiber and glass wool?
Fiberglass is an excellent inorganic non-metallic material. There are many kinds of glass fibers whose advantages are good insulation, heat resistance, corrosion resistance, high mechanical strength, and the drawbacks are brittle and poor wear resistance. It is made from glass ball or wasted glass through high temperature melting, wire drawing, winding and weaving. The monofilament diameter is between several microns and dozens of microns, the same as 1 / 20-1 / 5 of a human hair. Each bunch of fibre precursor consists of hundreds of or even thousands of monofilaments. Glass fiber is usually used as reinforcing material of composite material, electric insulation material, thermal insulation material, circuit board and various areas. 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.
