The thermal insulation decorative integrated board, also known as the external wall thermal insulation integrated board and the thermal insulation decorative board, is a relatively new product for external wall thermal insulation. It is characterized by a variety of decorative types, flexible application of thermal insulation materials, and cost saving and time saving, and is widely accepted by the market. It is made of raw materials through pre-production, maturation, molding, drying and cutting. It can be made into foam products of different densities and shapes, and can also produce foam boards of various thicknesses.

The breathing technology is used to eliminate negative pressure, prevent the accumulation of internal moisture, and prevent the formation of defects in the process of alternating high and low temperatures, avoiding the safety hazards of thermal insulation decorative integrated boards. It is precisely because of this performance that the safety performance of the board is very reliable. Drill "holes with a support rod outer diameter of +2 to 3mm" on the insulation layer and the base wall, and the hole depth of the concrete base is not less than 30mm; the hollow brick masonry base is not less than 60mm. And clean up the ash in the hole.

The prepared slurry should be used as soon as it is prepared, and it is advisable to use it up in about two hours, and it is never allowed to be used repeatedly. During the construction of the exterior wall insulation material project and within 24 hours after completion, the base and ambient air temperature should not be lower than 5°C. Avoid exposure to sunlight in summer.

The thermal insulation performance can surpass all other types of thermal insulation materials. However, the board also has hidden dangers, such as the problem that the vacuum degree is difficult to maintain: if it is damaged, the thermal insulation performance of the board will drop sharply. The existing construction process leads to too many board seams.
