What are glass wool products? Glass wool products are products made of glass wool. The air pores of this product are relatively small and can play a certain role in thermal insulation. , is a cooling product that can be used for safety protection. Glass wool products are suitable for the construction field. They can be used for thermal insulation and sound absorption and noise reduction. They are a relatively good building insulation material. Do you know what the implementation standards are for glass wool products? The following editor will introduce to you the implementation standards for glass wool products.
1. Implementation standards
Glass wool: GB/T?13350-2000 "Glass wool and its products for thermal insulation" and GB/T?17795-1999 "Glass for building thermal insulation" Cotton Products”.
2. Key points for design selection
1)? Moisture is very easy to migrate in mineral wool insulation materials, and the inherent looseness of its products will lead to high air permeability. Therefore, when selecting mineral wool products, you should consider its moisture migration, air permeability, compressibility and durability.
3) Reliable anti-penetration measures should be taken for ventilated roofs with exposed insulation layers and walls with cavities on both sides of the insulation layer to ensure that their insulation performance will not be significantly reduced.
4)? Due to the extremely easy migration characteristics of moisture in mineral wool insulation materials, liquid water will quickly drain from the bottom of vertical building components (such as exterior walls), and non-permanent moisture will not It has a significant impact on the thermal insulation performance of components. However, it may have an impact on horizontal building components (such as flat roofs).
5) Within the commonly used density range, the thermal conductivity of mineral wool products basically does not change with density. However, the thermal resistance of mineral wool products is directly proportional to their thickness. It can be seen that compression caused by load, compression creep under long-term load, and subsidence under long-term use will all lead to a decrease in thermal resistance.
6) The durability of mineral wool products mainly involves compression creep, subsidence and moisture deterioration. These changes will directly affect its thermal insulation performance.
3. Brief introduction
Glass wool is made of centrifugal glass wool mat, which uses Owens Corning (OC)’s unique patented centrifugal technology to fiberize the molten glass and The product is processed with environmentally friendly formula binder based on thermosetting resin. It is an elastic felt-like body made of glass fiber with a diameter of only a few microns. Different moisture-proof veneers can be selected according to the usage requirements. Online compounding. It has a large number of tiny air pores, which enable it to play the roles of thermal insulation, sound absorption and noise reduction, and safety protection. It is the best material for thermal insulation, sound absorption and noise reduction of steel structure buildings.
The above is an introduction to the implementation standards of glass wool products. Do you now know what glass wool products are? Glass wool products can be used to make thermal insulation layers and can be used in places with relatively good air circulation. In addition to being used to make building thermal insulation materials, glass wool products can also be used to make some other handicrafts. Glass wool products can also be seen in our daily lives. Glass wool products can absorb moisture without causing moisture pollution and are more environmentally friendly.
