Metal carved board, external wall insulation board has hidden function

I believe friends living in the North know that all residential buildings need to strengthen the insulation layer. Even self built houses in rural areas also need to be insulated from the external wall.

I used to think that the exterior wall panels of northern residential buildings are only designed for thermal insulation. I didn't expect that the metal exterior wall panels have three other functions. Today, I found that they are so important! Sure enough, everything has its existence!

01 basic function of metal carved board exterior wall panel - thermal insulation

The reason why the insulation layer is designed outside the house, the most basic function is insulation, because the outdoor temperature in northern China is very low in winter. Without this insulation layer, cold air will directly enter the room, making people feel very cold.

Our current residential buildings are basically made of reinforced concrete, but the thermal conductivity of reinforced concrete is very large, that is to say, the thermal insulation performance is not very good. Therefore, in the process of building the house, we need to add an insulating layer in the wall, so as to achieve better thermal insulation effect.

02 other functions of metal carved board exterior wall panel.

First function: Waterproof

The exterior walls of all residential buildings need to be waterproof. If the waterproof treatment of the exterior wall is improper, some rainwater will seep into the room along the exterior wall in rainy days, especially in continuous rainy days, which will increase the probability of house water leakage and affect our daily life.

Besides thermal insulation, the carved board exterior wall can effectively improve the waterproof performance of the exterior wall, because the exterior wall board needs waterproof treatment before installation. Pasting the thermal insulation board and spraying a layer of paint outside the thermal insulation board can play a better waterproof effect.

Basically, after the design of the outer wall layer, there are few problems of water leakage and seepage, especially for border friends, the waterproof effect of the insulation layer is very important!

Second function: sound insulation

For us, the sound insulation of the house is also a very important issue. If the sound insulation of the house is not good, we can clearly hear the noise of vehicles and pedestrians outside, which will seriously affect our rest and sleep.

In particular, some residential buildings close to factories, vegetable markets or on both sides of the road have greater requirements for sound insulation. If the sound insulation is not good, we will suffer from all kinds of noise every day and can't have a good rest, which will bring a lot of trouble to our life.

The external wall insulation board also has good sound insulation performance. Generally speaking, the materials used for insulation board have certain sound absorption capacity, which can absorb external noise, so as to reduce the impact of outdoor noise on the interior and give us a quieter rest environment.
