What is glass wool?Click here to consult us→Whats APP+86 13784788985

Glass wool is a lightweight insulation material mainly made of glass, which is melted at high temperature, fiberized, and made by adding resin adhesive. Glass wool is divided into glass wool board, glass wool roll felt, and glass wool insulation pipe shell. With its excellent thermal insulation, sound absorption, and fire resistance, it has become a widely used insulation solution in the fields of construction, industry, and home furnishings. The structure of glass wool is mainly composed of countless fine glass fibers. This porous structure not only effectively blocks heat transfer, but also absorbs sound waves, making it a material that combines functionality and environmental friendliness.

Characteristics and advantages of glass wool

1. Excellent thermal insulation performance

Glass wool has an extremely low thermal conductivity (0.033W/m · K at 25 ℃), which can effectively reduce heat transfer and maintain stable indoor temperature. This makes it an ideal choice for insulation of building walls, roofs, and pipelines, helping to reduce energy consumption and improve energy efficiency.

2. Excellent sound absorption performance

Due to the porous structure of glass wool, after testing by Hebei Lanxuan Company, the sound insulation effect of glass wool is between 5-10dB. Sound waves entering the material will be reflected and absorbed multiple times, thereby reducing the propagation of sound energy. Widely used for indoor wall sound insulation, ceiling and mechanical equipment noise reduction treatment.

3. Excellent fire resistance performance

Glass wool is an inorganic non combustible material that is resistant to high temperatures and can withstand temperatures of approximately 700 ℃ without burning. Its fire resistance meets the A-level standard for building materials and can effectively enhance the fire safety of buildings.

4. Lightweight and easy to construct

Glass wool is lightweight in texture, easy to cut and lay during construction, and has good elasticity to adapt to complex building shapes, saving installation time and costs.

Application areas of glass wool

1. Building insulation

Glass wool is widely used for thermal insulation of steel structure roofs and walls, and the Huaerda glass insulation roll is the most widely used in the field of steel structures.

2. Acoustic Engineering

Due to its excellent sound absorption performance, glass wool is often used in conference rooms, theaters, recording studios, and other places with high acoustic requirements to reduce noise and echo.

3. Industrial insulation

Glass wool can be used for insulation of industrial equipment, pipelines, and storage tanks, helping to reduce energy loss and improve the operational efficiency of industrial facilities.
Precautions for glass wool

Although glass wool has many advantages, the following points should be noted during use and installation:

1. Protective measures: Glass wool fibers may cause slight irritation to the skin and respiratory tract. It is recommended to wear protective gloves, masks, and goggles during construction.
2. Moisture proof treatment: Although glass wool itself has a certain degree of moisture resistance, a moisture-proof layer should be added in high humidity environments to prevent the performance from deteriorating after the material absorbs moisture.

summary

Glass wool has become an indispensable insulation material in modern architecture and industry due to its superior insulation, sound absorption, and fire resistance properties. It can not only effectively improve energy efficiency, but also enhance the comfort of living and working environments. Meanwhile, as an environmentally friendly material, glass wool also occupies an important position in sustainable development. Choosing glass wool means choosing an efficient, economical, and environmentally friendly insulation solution.
