During the construction of extruded polystyrene boards, concealed works inspection and acceptance should be carried out for the base layer. Only after passing the inspection can the leveling layer be constructed, and the drainage slope of the leveling layer should meet the design requirements. Various embedded pipe fittings passing through the roof, including the root and base layers, and protruding roof structures. Extruded polystyrene board can maintain low thermal conductivity, and it also has a unique and perfect closed cell honeycomb structure. It is an environmentally friendly material with high-quality properties such as high pressure resistance, moisture resistance, air tightness, non water absorption, corrosion resistance, low thermal conductivity, lightweight, and long service life.

Extruded polystyrene board has a low density and light weight. When used in construction projects, it can reduce the weight of the building, lower its load, reduce structural costs, and is easy and fast to construct. Pay attention to the safety of extruded board structures, understand the relevant work standards within your scope of responsibility, and be very clear about certain technical work. Especially for parts that are prone to quality issues, it is necessary to clarify everyone's responsibility for the problem.

Before using the extruded board, it should be polished and leveled. If there is uneven bonding between the extruded board and the surface, polymer mortar should be used for leveling. Before leveling, an interface agent should be applied, and a thin layer of interface agent should be applied to the surface of the extruded board. After drying, the polymer mortar should be evenly applied to the extruded board. The rainwater pipe clamps, embedded iron parts, and equipment through wall pipes on the exterior wall should be installed in advance and coordinated with each other.

The extruded board project needs to have insulation performance, and the lower the thermal conductivity of the material, the thinner the required design thickness. Extruded polystyrene board should have good dimensional stability. If used in engineering, the board is prone to warping and deformation, which can easily lead to cracking and water seepage of the outer surface.
