In the construction industry, external wall insulation is an important link. In this link, glass fiber cloth is a very important material. It not only has strong toughness, but also strengthens the strength of the wall, making it less prone to cracking. It can also be used in combination with materials such as thermal insulation mortar. It has a good thermal insulation and waterproof function, and the sound insulation and noise reduction effect is also very good, so many building exterior walls are now using this method for thermal insulation work. Since glass fiber is not the main material for external wall insulation, how do we choose this kind of cloth?
The special glass fiber product for exterior wall is made of glass fiber as raw material, and has very good tear resistance and alkali resistance. Therefore, it can be well used in construction, and its performance is very stable. When buying, we must first look at its appearance. Products with stable quality are usually milky white, with good color and certain brightness, while products with low quality are made of inferior materials. The color is black; there is also the feeling to the touch. Products with stable quality do not feel any feeling, and they also have a certain elasticity. On the contrary, products with poor quality feel very rough to the touch, and there are some burrs, which are very easy to hurt our fingers. And there is also a clear gap in their hardness, which can be carefully compared. That's where the difference comes out.
Although the outer wall fiberglass cloth is used on the outside of the wall and is also covered by thermal insulation mortar, its main thermal insulation and enhancement functions mainly rely on the fiber cloth, so it can't make do with it when it is selected, and it is necessary to use good products. , so as to better protect our walls and have a better thermal insulation effect.
