The hard film formed by the outer mold protective layer of the extruded board is uniform, and the closed cells inside are continuously and evenly foamed to form a honeycomb structure. It has the characteristics of high compressibility, light weight, non-absorbent, breathable and resistance. It is wear-resistant and non-degradable.

The temperature during the construction of the extruded board is not lower than 5 degrees, and the temperature is not lower than 5 degrees 24 hours after the construction is completed. It is not suitable to construct under strong light in summer, and it is prohibited to work in wind force of level 4 or above or in rainy days. Since the strength of the benzene board substrate is much lower than that of the extruded board, it often breaks, and the thermal insulation performance is lower than that of the extruded board. Due to its small porosity and relatively low water absorption, it is easy to get wet when used.

A protective layer of L-shaped galvanized iron sheet should be placed within the thickness range of the upper floor of the outer mold of the extruded board. Its function is to protect the upper end of the insulation board and prevent the concrete from filling the dovetail groove of the extruded board of the floor section when the wall is poured. What are the design specifications of the extruded board? The general specifications are 120*60 or 240*60. The thickness can be customized by ourselves. The extruded board is divided into fire safety levels. Extruded boards are now mostly used for exterior wall insulation.

There is no outer layer of caulking between the extruded boards. When the roof area is large, sealing tape is pasted between the board seams. The main reason is that the foaming structure is closely connected and there is no gap between the walls, so the compressive performance of the extruded board is improved. The fixings are installed 8 hours after the extruded board is pasted on the exterior wall, and are completed within the next 24 hours. Use an impact drill to drill holes at the position required by the design, with a hole diameter of 10 and a depth of about 60 into the base wall. The fixings are anchored into the base wall.
