In the cold winter, not only do you have to keep yourself warm and cold, but also the warmth of your home is essential. Wall insulation is mainly divided into external wall insulation and internal wall insulation, then the interior wall insulation coating which is good, interior wall insulation coating price is how much? With Xiaobian together to understand the next!
Internal wall insulation coating which is good
First, polyurethane foam
1, advantages
Polyurethane foam is a commonly used internal wall insulation material. It has good thermal insulation properties and low thermal conductivity. It is a good material for thermal insulation in building decoration. And its foam hole closure rate of 95%, rain does not leak into the room from the pores, waterproof effect is very good.
2. Disadvantages
If the housing trenches and gutter flatness are not good, the drainage speed will be affected, which will affect the insulation effect of polyurethane foam. Therefore, it must be used in conjunction with other waterproof materials. Polyurethane foams should also pay attention to the temperature during construction. If the temperature is too low, the foaming rate of the polyurethane foam will be reduced. Therefore, weather conditions must be taken into account.
Second, polystyrene foam board
1, advantages
This kind of insulation coating surface has low water absorption rate and good anti-permeability. It can effectively prevent the wall surface from dampness, mildew, and falling off when used in home furnishings. In addition, the polystyrene foam board has low density, good impact resistance, and independent bubble structure. If it is a small area, the damage will not generally affect the insulation effect of the entire wall.
2. Disadvantages
The disadvantage of the polystyrene foam board is that it is easy to burn, and the smoke generated after combustion is toxic and harmful to people's health. Moreover, the quality of the insulation material is unstable, and the foam board is easy to shrink and crack during use.
Third, glass fiber cotton
1, advantages
a, good heat insulation. Glass fiber cotton has a lot of tiny gas holes, the fibers are irregularly arranged, and it is a very good insulation material.
b. Non-flammable. Glass fiber cotton is not as easy to burn as polystyrene foam board, nor is it deformed or embrittled. It is very resistant to high temperatures and its combustion performance reaches Class A1.
c. Environmental protection is non-toxic. Glass fiber cotton does not add any binder in the production process, so it will not emit toxic and pungent odors when it is exposed to high temperatures.
2. Disadvantages
a. Its raw material is glass, and glass is easy to break and it is not safe.
b, poor wear resistance. It can easily lead to damage over a long period of time. Once sharp objects are scratched on the surface, it is difficult to recover.
Internal wall insulation coating price is how much
Insulation coating prices vary widely, different brands have different prices, the general price of insulation coating is: 700 yuan -1500 yuan.
Nano antibacterial interior wall insulation coating 388 yuan
Scratch interior wall insulation coating 300 yuan
Thermal insulation interior wall insulation coating 350 yuan
About the interior wall insulation coating which is good, the content of the interior wall insulation coating price introduced to this, I hope to be helpful! The interior wall insulation construction is very important, but also in the selection of materials should be cautious, hope that the above content can help everyone !
