When the extruded board design unit conducts design briefing to the construction and supervision units, it is necessary to focus on clarifying the specific construction methods and related construction technical requirements such as cracking and leakage prevention of the exterior wall and air drum prevention. Make a good design for exterior wall insulation and carry out quality inspection of exterior wall insulation construction according to regulations.

In order to strengthen the construction quality management and quality acceptance supervision of the exterior wall insulation project of housing buildings, consolidate the quality responsibility of the participating construction units, and improve the construction quality of the exterior wall insulation project of housing buildings. On the other hand, the extruded board can also be evenly peeled to release a certain amount of internal stress.

And because of its thermal insulation performance, it can effectively reduce the cold and thermal bridge effects, protect the main structure of the building, extend the service life of the building, and make the indoor room warm in winter and cool in summer, improving the living comfort. You can observe the surface of the product. If there are cracks or foam on the surface of the polyurethane insulation board, it is best not to buy it, because these reasons are likely to be caused by errors in the production process or too long storage time. In addition, pay attention to its insulation level and the thickness of the insulation board, and choose products of different thicknesses according to different requirements.

When extruded boards are used for external corner construction, they should be properly extended beyond the wall by a certain distance to ensure the verticality of the external corner. After all the extruded boards are pasted, they can be uniformly marked and cut, and polished to make them smooth. The construction technology requirements of the extruded board design unit are that when extruded boards are pasted, the board seams should be pressed tightly, the adjacent boards should be flush, and the gap between the control boards should not be greater than 2m during construction. After they are pasted to the wall as required, they should be repeatedly flattened with a 2m ruler to ensure their flatness and strong bonding.
