Why is the penetration rate of external wall thermal insulation decoration in integrated board not high?

Easy to fall off, short service life, resulting in low popularity.

A house is a home. China people's obsession with houses has been deeply rooted, and building materials have become more and more solid through the evolution of past dynasties. From thatched cottages that fall when the wind blows, to wooden houses that can be fixed well without nails, adobe houses with better thermal insulation based on local materials, and the popularity of masonry structures also reflect the improvement of living standards from the side. In the cold winter, if the house leaks air everywhere, even if the air conditioning brand at home is no matter how good, heating will not help, so builders should do a good job of external wall insulation when building. The traditional way not only requires workers' skills to be extremely high, but also affects the technology if the weather is not willing to have a storm, so the insulation board was born. I thought it would be widely used, but many people still refused to use it. One is that the material is not good enough to fall off easily, and the other is because its service life is too short.

First, the easy-to-fall insulation board adopts multilayer structure. Buyers usually only care about whether the decorative patterns on the outside are beautiful and the thickness is up to standard, but they can't check the stability and quality of the inner materials. Because it is a new industry, the manufacturers in the market are also mixed, and it is inevitable to encounter inferior manufacturers. If you meet a poorly skilled construction worker, it is easy to fall down, so many unused people are unwilling to take risks.

Second, the service life is short. Although the traditional external wall insulation method has long construction period, high price and relatively simple appearance, it has long service life, even if it is not beautiful, it can be used for many years at a time. Generally speaking, it is more cost-effective, but the best quality insulation board can only be used for about two years. Such a huge project is not like changing clothes when they are worn out. Renovation is a big expense, even those with deep pockets are reluctant to part with it.
