Advantages of extruded board materials: when it needs to be transported, it should be handled with care, lifted sideways and placed sideways, and the platform should not be placed flat. Wooden blocks should be placed 50cm from the end of the board, and the stacking place should be flat. Prepare necessary hand-held tools and mobile distribution boxes, and use external lifts for vertical transportation. Apply bonding mortar evenly on the back of the polystyrene board and then place it on the cement wall. The polystyrene board is drilled outward with a hammer drill, and the polystyrene board is fixed with anchor bolts. Anchoring operation: After drilling, put the ground anchor into the hole and screw in the screw with a hammer.

The surface of the extruded board is the so-called thin plaster surface, that is, the polymer adhesive mortar is applied to the insulation base. That is to say, it is directly applied to the bottom of the insulation layer, with a thickness of about 2-3mm, and there is a reinforcing material inside. The extruded board has both the effect of thermal insulation and the effect of waterproofing and moisture-proofing. It has high compressive strength and relatively low thermal conductivity. The surface forms a closed-cell honeycomb structure, plus a certain thickness, so it can form different pressures and bring excellent insulation effect.

Extruded board has the advantages of small water absorption capacity and very low water vapor permeability. Using extruded board as the external insulation layer can prevent the wall of the house from being cold and doubtful, reasonably improve the moisture and temperature conditions of the wall, and further improve the thermal insulation of the wall. Foam board has the following advantages as an insulation wall: the density coefficient of the foam board is small, the impact resistance is good, and it has enough ability to buffer the external impact by changing and restoring the shape. Independent bubble structure, small area damage will not affect the whole wall.
