Polyethylene high-expansion foam is suitable for external wall insulation of newly built public buildings and civil buildings, and energy-saving enclosure systems of frame structures. It is applied to the surface of buildings, components and substrates to protect the base and prevent it from falling off or cracking under long-term self-weight and environmental effects.

Polyethylene high-expansion foam is embedded with anchor bolts after drilling holes to fix the anchors. The connectors of L-type anchors and H-type hangers are fixed by expansion bolts. In the separated gaps, fill the insulation caulking strips (foam caulking strips) and paste masking tape at both ends of the gaps. The third is the ground moisture-proof insulation layer, which is widely used in the ground moisture-proof of various buildings. It is laid under the roadbed of highways, railways and airport runways in high-cold areas. It can control the thermal expansion and contraction of floor tiles and has excellent structural load-bearing function.

External wall insulation is more prone to powdering and poor weather resistance than the latter, resulting in shedding. (The possibility is low, and the completion time of this building should not be too long). In addition, the horizontal wire rock wool board has poor integrity and is easy to peel off layer by layer. If vertical wire rock wool tape is used, the effect may be better.

In the case of polyethylene high-fold foam, try not to buy it, because these reasons are likely to be caused by errors in the production process or the merchant's storage time is too long. The insulation effect of the exterior wall is better than that of the exterior wall. The waterproof effect is good. In the natural environment, the water absorption rate of the extruded board is extremely low. Combined with the water resistance of the special mortar, rainwater and humid air are effectively blocked outside the system.

Polyethylene high-fold foam is suitable for buildings with a small overall weight, so only special mortar is needed to directly stick it to the wall to achieve the specified bonding strength requirements. Polyethylene high-fold foaming solves the cracking and waterproofing of external insulation projects, which is an important technical approach and engineering technical problem to solve negative wind pressure damage, frost heave damage, or water immersion damage.
