The difference between composite rock wool board and glass wool roll felt
Composite rock wool board and glass wool roll felt are two common building insulation materials, which have some differences in performance and application. The following is a detailed comparison of these two materials.
1、 Material composition
Composite rock wool board is a board made from inorganic fibers made by centrifugation or blowing method after natural rocks are melted at high temperature, and then mixed and pressed with adhesives such as thermosetting resin. Glass wool felt, on the other hand, is a soft and fluffy insulation material made by adding thermosetting resin adhesive to melted glass fibers and hot pressing the felt.
2、 Performance characteristics
1. Insulation performance: Composite rock wool board has a high thermal conductivity, but its insulation performance is relatively poor compared to glass wool felt. However, glass wool felt has a compact fiber structure, low thermal conductivity, and good insulation performance.
2. Fire resistance: Composite rock wool board is a non combustible material with excellent fire resistance, which can meet the fire resistance requirements of buildings. Glass wool felt also has certain fire resistance, but it is slightly inferior to composite rock wool board.
3. Sound absorption performance: Glass wool felt has good sound absorption performance, which can effectively reduce noise pollution. However, the performance of composite rock wool board in terms of sound absorption is relatively weak.
4. Compression resistance: Composite rock wool board has high compressive strength and is suitable for situations that require bearing certain loads. Glass wool felt is relatively soft and has poor compressive performance.
5. Environmental performance: Both materials are inorganic fiber materials, free of harmful substances and harmless to the environment.
3、 Application field
1. Composite rock wool board, due to its high compressive strength and fire resistance, is often used in exterior wall insulation, roof insulation, partition walls and other situations that require bearing certain loads and fire protection requirements. In addition, composite rock wool board can also be used for insulation and fire prevention of ships, vehicles and other transportation vehicles.
2. Glass wool felt, due to its excellent insulation and sound absorption properties, is often used in indoor insulation, partition walls, ceilings and other occasions of buildings to reduce energy consumption and noise pollution. Meanwhile, glass wool felt can also be used for insulation and noise reduction of equipment such as air conditioning ducts and fan rooms.
4、 Construction precautions
During the construction process, suitable insulation materials should be selected based on specific engineering requirements and occasions. For situations that require high load-bearing capacity and high fire resistance requirements, composite rock wool boards should be given priority; For indoor environments that require reducing energy consumption and noise pollution, glass wool felt can be chosen.
When installing insulation materials, attention should be paid to the splicing and fixation of the materials, ensuring that they are tightly fitted, flat and without gaps, and avoiding the generation of air convection and thermal bridge effects.
During the construction process, attention should also be paid to protecting insulation materials to avoid damage and pollution, in order to ensure their long-term effective insulation performance.
In short, composite rock wool board and glass wool roll felt are two building insulation materials with different properties and applications. In practical engineering, suitable materials should be selected according to specific needs and occasions, and attention should be paid to details during the construction process to ensure the quality and effectiveness of insulation engineering.
