How is the thermal insulation effect of prefabricated houses?

2024-08-20

In order to increase the thermal insulation performance of the Prefab Houses, an insulation layer is usually added to the inner interlayer of the color steel plate. The insulation layer can be made of polystyrene (EPS), rock wool board, polyurethane, etc. to improve the thermal insulation effect of the Prefabricated House. These materials have the characteristics of low thermal conductivity, light weight, fire retardancy, etc. In terms of fire resistance, the fire resistance grade of rock wool is A, and EPS and polyurethane are B. The thermal insulation of polyurethane is better than EPS and rock wool. The thermal insulation performance is not only related to the selected material, but also to the density of the material and the thickness of the Sandwich Panel. The higher the material density, the thicker the sandwich panel thickness, and the better the thermal insulation performance. In terms of cost, the price of polyurethane is higher than EPS and rock wool. Therefore, customers can choose wall panels according to the regional temperature environment and their own budget.
