The characteristics of glass wool

In order to improve the insulation of buildings, the usual practice is to cover the exterior of the house with insulation materials or fill the walls with insulation materials. "Fiber based thermal insulation materials" and "foamed plastic based thermal insulation materials" are often used as thermal insulation materials for houses.

Glass wool is an insulation material based on inorganic fibers, which contain air between the fibers and are difficult to transfer heat.

Raw materials and manufacturing methods of glass wool

Glass wool melts raw glass at high temperatures and turns it into fine fibers through centrifugal force. Using recycled glass primarily made from recyclable waste to make it an environmentally friendly material.

Types of glass wool

There are various types of glass wool insulation materials, including board type and blow in type. In addition, according to the fiber density (K=kg/㎡), the higher this number, the better the insulation performance.

Insulation performance of glass wool

The performance of insulation materials is determined by the difficulty of heat transfer. This is represented by the indicator "thermal conductivity [W/m · K]". The thermal conductivity is a number that represents how much heat is transferred per second when there is a temperature difference of 1 ℃ between the front and back of an insulation material with a thickness of 1m and an area of 1m2 In other words, "low thermal conductivity=difficult to transfer heat=high insulation performance.".

The advantages of glass wool

1. Excellent insulation performance

Glass wool has a low thermal conductivity and excellent insulation performance, which can effectively prevent the invasion of cold and hot air from the outside and maintain stable indoor temperature. This makes glass wool widely used in the roofs, walls, floors and other parts of buildings, which can significantly improve the insulation performance and energy-saving effect of buildings.

2. Sound absorption and noise reduction

Glass wool has good sound absorption and noise reduction performance, which can effectively absorb and reduce noise, and improve the comfort of indoor environment. Widely used in KTV, recording studios, cinemas and other places. The use of glass wool can effectively reduce the spread and interference of noise, and improve people's quality of life.

3. Convenient construction

Glass wool construction is convenient, easy to install, and not easily damaged. At the same time, glass wool will not cause harm to the environment and human health.

4. Affordable price

Glass wool is relatively affordable and has a higher cost-effectiveness compared to other high-end materials.

Disadvantages of glass wool

1. Poor durability

The durability of glass wool is relatively poor, and it is easily affected by factors such as ultraviolet radiation and oxidation, leading to a decrease in performance. Therefore, when using glass wool, it is necessary to pay attention to maintenance and upkeep, and regularly replace or refurbish it.

2. Not suitable for humid environments

Glass wool is not suitable for use in humid environments, as it is prone to moisture absorption and affects insulation performance and service life. Therefore, when using glass wool, it is necessary to pay attention to environmental humidity and avoid using it in damp environments.

3. High support system requirements

In order to maintain the shape and stability of the glass wool, it is necessary to use a high-strength support system for fixation and support. If the support system is not strong enough or installed improperly, it is easy to cause problems such as deformation and displacement of the glass wool.
