What are the thermal insulation core materials of color steel sandwich panel?

The color steel sandwich panel is made of two layers of color coated steel plates as the surface layer, which has both stiffness and heat insulation but low strength. For example, hard foam, rock wool, polyurethane and other thermal insulation materials are used as core materials, which are compounded on a special automatic production line and are structural plates with bearing capacity. Because of its structural characteristics, this kind of board is also called "sandwich" board. It can be divided into roof panel, wall panel, partition panel and ceiling panel according to the different parts and panel types of buildings.

As a new multi-functional building panel, the color steel sandwich panel has the characteristics of excellent thermal insulation, sound insulation, strong bearing capacity, bright color, flexible installation, low cost, waterproof, anti-seismic, etc. Since the 1980s, it has been widely used in large-scale industrial plants, steel structure plants, mobile rooms, clean workshops, building floors, temporary houses, warehouses, cold storage, gymnasiums, supermarkets and places requiring thermal insulation and fire protection.

The color steel sandwich panel is beautiful in appearance, bright in color and good in overall effect. It integrates load-bearing, heat preservation, fire prevention and waterproof, and does not need secondary decoration. It is fast and convenient in installation, short in construction period and good in comprehensive benefits. It is a kind of efficient building material with wide use and great potential.

The good performance of color steel sandwich panel depends not only on the panel and the best combination of panel and core material, but also on the material of core material. However, the thermal insulation core materials commonly used for color steel sandwich panels at present have more or less disadvantages, and most of them cannot meet the requirements of high efficiency fire protection and thermal insulation, high temperature resistance, environmental friendliness and other characteristics at the same time. On the other hand, there are more and more manufacturers of this kind of product, and the products produced are similar to each other, resulting in fierce market competition. Therefore, enterprises should adopt a new type of replacement insulation core material to catch up with the strong momentum of continuous renewal and development in the field of color steel sandwich panels, improve the competitive advantage of products, and achieve greater economic benefits.
