Introduction to glass wool roll felt: Glass wool roll felt is a roll material made to meet the needs of large-area laying. In addition to maintaining the characteristics of thermal insulation, it also has excellent shock absorption and sound absorption properties, especially for medium and low frequencies and various vibration noises. It has a good absorption effect, which is beneficial to reducing noise pollution and improving the working environment. Glass wool felt with aluminum foil veneer also has strong heat radiation resistance and is an excellent lining material for high-temperature workshops, control rooms, machine room inner walls, partitions and flat roofs.

Advantages of glass wool roll felt:
1. The internal fibers of the glass wool used in Shengyuan steel structure buildings are evenly distributed, usually between 4-6 microns, which is far better than the national standard and ahead of most similar products.
2. Fire resistance meets the requirements for Class A/1 non-combustible materials in the GB8624-2019 standard.
3. The water repellency rate exceeds 98%, and it uses the best veneer lamination on the market, which can effectively resist the adverse effects of moisture in the use environment and ensure continuous and stable thermal insulation and sound absorption and noise reduction capabilities.
4. The slender and evenly distributed fibers ensure the product's excellent thermal insulation performance and sound absorption and noise reduction effect.

Small problems that arise when glass wool roll felt is applied to steel structure buildings are called [condensation problems]
When water vapor in the air reaches its saturation value at a certain temperature, it condenses into liquid water, causing condensation. In light steel structure buildings, there are two main forms of condensation:
1. Surface condensation:
On the inner surface of the glass wool insulation layer (more common in winter in the north) or on the finishing layer on the outer surface of the glass wool insulation layer (in the summer in the south), especially where cold bridges occur.

2. Internal condensation:
The side of the color steel plate facing indoors (more common in winter in the north) or the side of the glass wool facing layer facing outdoor (summer in the south). This part of the moisture will remain in the glass wool, so it is called internal condensation.
