Polyethylene high-fold foaming can be added with paint. The production period is long, the operation links are many, and the details are complicated. Due to the uncontrollable construction, it is very likely that the exterior wall will fall off, crack, hollow and other problems will occur.

The insulation layer of polyethylene high-fold foaming has a concrete protective layer of no less than 5cm on the outside, which is integrated with the wall. There is no falling off and burning. The construction is simple and easy to operate. It is completely enough to replace the traditional exterior wall thin plastering insulation system based on rock wool board and inorganic permeable polystyrene board. The base layer is not treated with interface agent. Because the surface of the rock wool board contains water repellent, the bonding strength of direct bonding with bonding mortar cannot meet the requirements. Therefore, a layer of hydrophilic interface agent should be applied to the bonding surface before construction (the bonding surface of the rock wool board that fell off in the video has no bonding mortar).

Polyethylene high-fold foaming should also pay attention to the raw materials of the product. Generally, polyurethane insulation board is foamed from black and white materials. The appearance of these raw materials is basically the same, so be careful when purchasing. Due to the physical properties of the insulation layer and protective layer materials and the environmental factors of the building, the safety of the insulation decorative board is mainly damaged by earthquakes, wind, external impact, fire, rain, snow, frost heave and other important factors.

The external wall insulation anchor is to completely eliminate the operation link of the production of polyethylene high-fold foaming and delamination, improve the overall safety of the insulation decorative board, use anchors, fasten the finishing layer, and firmly connect the insulation board to the wall again. Since the extruded board adopts the fixing method mainly based on bolt anchoring, there is no particularly strict requirement for the base surface of the building, it does not affect or interfere with the normal residence or use of users, and the construction speed is fast.
