Overall insulation decorative system as a whole is divided into three functional layers: PTFE fluorocarbon coating: provide surface more than 20 years of life, maintenance-free self-cleaning function, resistant to many chemicals, corrosion-resistant complex environment, high-end decorative and other properties. High-strength carrier protective layer: mainly to meet the requirements of impact strength, and as tetrafluoroethylene fluorocarbon coating carrier XPS, EPS insulation layer: the main provider of energy-saving effect of thermal insulation to meet the design requirements. Second, the the overall insulation decorative Introduction: the development of building energy efficiency, we must wall materials with good thermal insulation properties, in order to enhance the thermal insulation properties. If the outside of the wall layer of insulation, not only to protect the main structure, extending the life of the building, but also to eliminate the impact of building local "thermal bridges" to improve the waterproof function of the wall, improve Wall wet conditions, saving heating energy consumption and reduce air conditioning costs in summer, to avoid cracks in the outer wall layer, increasing the housing area, reduce the housing weight. Especially the old buildings for energy saving, without relocation of tenants, save a lot of manpower and resources, while avoiding damage to the insulation re-decoration, new look of the old buildings, and beautify the urban environment. Only 10 cm thick insulation material layer to prevent the effects of heat loss, equivalent to 4m thick concrete or 1m thick clay brick wall.
