Development of exterior wall metal engraving board Nowadays, the external insulation of building exterior wall is mainly made of external insulation method, that is, the insulation board is attached to the outer facade of the building exterior wall, and the insulation measures consisting of plastering and hanging net are attached. The method mainly uses organic insulation materials such as benzene board and extruded board. The practice in recent years in China has proved that this kind of insulation method has many congenital ills. In summary, there are three main problems: first, building insulation and structural life are different; second, fire hazards cannot be avoided; third, outside Insulation can not be overcome. For the above three problems, it is impossible to solve the problem by using the external insulation method.

 At the same time that various ills of building exterior insulation methods frequently appear, the traditional insulation industry is also facing huge development bottlenecks. The main problems are as follows: First, product homogeneity is common, second, severe overcapacity, and third, products. Single function.

So how to solve the bottleneck of the development of the traditional insulation industry? The only answer is to integrate the two industries of insulation and decoration to form a wall with integrated insulation and decorative structure, which will be the only way to develop insulation in the future.

The thermal insulation decoration integration technology has the following advantages: the integration of insulation and decoration, the construction process is greatly reduced, and the heat transfer coefficient of the main part of the wall can meet the limit of the average heat transfer coefficient of the wall specified by the current building energy-saving design standard in the building area. It has many excellent features such as durability, fire resistance, impact resistance, convenient construction, low comprehensive cost, low quality and common disease, and the same life span as buildings. Compared with traditional thermal insulation systems such as exterior insulation systems, thermal insulation and decorative integrated systems have significant advantages in terms of construction, safety, durability and economy.
