How to select fiberglass fabric for exterior wall insulation?
In the construction industry, exterior wall insulation is an important part of this link in the fiberglass cloth is a very important material, it is not only toughness, can reinforce the wall strength, so that it is not easy to crack outside, and thermal insulation mortar and other materials combined with a very good thermal insulation and waterproofing, and sound insulation and noise reduction effect is also very good, so now a lot of building walls are used in this way to carry out the work of thermal insulation. Since fiberglass is not the main material for exterior wall insulation, how do we pick this cloth?
Special fiberglass fabric products for external walls are processed and made of fiberglass as raw material, which has very good tear resistance and alkali resistance. So it can be well used in building construction, and its performance is very stable. In the purchase, we first want to watch its appearance, stable quality products are usually milky white, good sense of color with a certain brightness, and low quality products are used in some poor quality material processing production, the product color black; and then there is the feeling of touching, stable quality products do not have any feeling to touch, and they also have a certain degree of elasticity. On the contrary, bad quality products, feel very rough, and there are some burrs in, very easy to hurt our fingers. And their hardness also has a significant difference, we can make a careful comparison. So the difference comes out.
Although the exterior fiberglass fabric is used outside the wall, and also covered by insulation mortar inside, but its main insulation and enhance the function of the main fiber cloth, so in the selection can not make up things, to use good products, so that we can better protect our walls, but also have a better thermal insulation effect.
