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, can strengthen the wall strength, make it not easy to crack, but also has good thermal insulation and waterproof function when combined with thermal insulation mortar and other materials, and has good sound insulation and noise reduction effect. So now many building external walls use this method for thermal insulation. Since glass fiber is not the main material for external wall insulation, how do we choose this cloth?

The special glass fiber for exterior wall is not manufactured with glass fiber as raw material, and has very good tear resistance and alkali resistance. So it can be well used in construction, and its performance is very stable. When purchasing, we should first look at its appearance. The products with stable quality are usually milky white, with good color sense and certain brightness, while the products with low quality are processed with some inferior materials, and the color of the products is black; What's more, there is a sense of touch. Products with stable quality have no sense of touch, and they also have a certain degree of elasticity. On the contrary, products with poor quality feel very rough and have some burrs, which is very easy to hurt our fingers. And their hardness also has obvious differences. We can make a careful comparison. So the difference comes out.
Although the glass fiber cloth is used outside the wall and is also covered in the thermal insulation mortar, its main thermal insulation and enhancement function mainly depends on the fiber cloth, so it can't make do when selecting, so we should use the product well, so that we can better protect our wall and have better thermal insulation effect.
