Glass wool is an insulating material made from glass fibers called borosilicate glass, which are arranged using an adhesive to form a wool-like texture. It consists of silica sand, recycled glass and fixative, forming the perfect combination to provide excellent insulation and coating for houses.
Excellent Thermal Insulation: Glass wool effectively reduces heat transfer, leading to improved energy efficiency and reduced heating and cooling costs.
Superior Acoustic Insulation: Its fibrous structure absorbs sound waves, reducing noise pollution and enhancing the acoustic comfort of buildings.
Lightweight and Flexible: Glass wool is lightweight and can be easily cut and installed in various applications, ensuring convenience and flexibility during installation.
Non-Combustible: It is inherently fire-resistant, providing an added layer of safety in case of fire incidents.
Durable and Long-Lasting: Glass wool is resistant to aging, ensuring its insulation properties remain intact over an extended period.
Environmentally Friendly: It is made from recycled glass and is recyclable, reducing environmental impact and promoting sustainability.
Residential Buildings:
Glass wool is commonly used for insulating roofs, walls, and floors in residential buildings, ensuring energy efficiency and thermal comfort.
01
Commercial Buildings:
It is widely employed in offices, shopping malls, hotels, and other commercial structures to enhance thermal and acoustic insulation.
02
Industrial Facilities:
Glass wool is utilized in factories, warehouses, and industrial facilities to control temperature, reduce noise, and improve working conditions.
03
HVAC Systems:
It is a popular choice for insulating air ducts and pipes, preventing heat loss or gain and maintaining optimal temperature levels.
04
Transportation:
Glass wool is used in the automotive and aerospace industries to provide thermal and acoustic insulation in vehicles and aircraft.
05
Glass wool is typically the more economical choice, establishing it as the standard material for large-scale residential projects where budget is a primary driver. It provides a strong balance of thermal performance and cost for most standard insulation needs.
Rock wool’s higher price point is justified by its superior performance metrics. It is selected when enhanced fire resistance, acoustic control, or moisture durability are non-negotiable project requirements, positioning it as the go-to material for specialized industrial, commercial, and high-performance building applications.
Centrifugal glass wool is the glass as the main raw material and then mixed with various other auxiliary materials in a certain proportion and sent into the glass melting furnace after full melting, the melted solution flows out through the leakage plate and enters the centrifuge.
Driven by a high-speed centrifuge, the equipment operates at high velocity, centrifuging the glass raw material outward to form fine, dense streams of glass.
Subsequently, under the influence of a high-temperature, high-velocity flame, these glass streams are further attenuated into fibers; an atomized binder is then sprayed onto them.
Driven by the negative-pressure airflow generated by a fiber-collecting mesh belt, the fibers—now coated with the resin binder—settle onto the moving belt, forming a uniform mat.
The material then enters a constant-temperature curing oven to complete the curing process and set the product's shape. Once the setting process is complete, the product is cut into predetermined dimensions and immediately packaged.
Proper Measurement: Accurate sizing prevents gaps and thermal bridges.
1
>>
Safety Equipment: Wear gloves, masks, and protective clothing during installation.
2
>>
Vapor Barriers: Install where necessary to prevent moisture accumulation.
3
>>
Ventilation: Ensure adequate airflow in attics and enclosed spaces.
4
>>
Compression Avoidance: Don’t over-compress glass wool as it reduces effectiveness.
5
>>
Sealing Joints: Tape all seams in faced glass wool for an airtight installation.
