For XPS extruded boards with surface grooves, the groove area is much smaller than the area with skin, so the thermal conductivity loss rate of slotted XPS extruded boards is smaller. The more skin loss there is, the greater the loss of thermal conductivity. So after removing the skin on both sides, the thermal conductivity significantly decreases.

The incorrect construction method of slotting the surface of the extruded board can cause the board to fall off directly, and different insulation boards require the use of professional construction methods. Some construction companies now hire temporary workers when installing insulation boards due to their insufficient strength, and these phenomena need to be avoided. If the foam of the extruded board is too light during production, the compressive strength of the product will decrease. To truly achieve thermal insulation and good strength, extruded polystyrene boards can only achieve ideal results with appropriate foaming. The uniformity of the bubble structure determines the performance of the product.

Before installation, the basement must be cleaned of any debris such as floating ash, soil, oil stains, etc. Material mixing is also an important component of the installation process. The ratio of dry powder to water is about 51. Of course, adjustments can also be made based on the viscosity of the mortar and the local temperature. When storing products, it is important to pay attention to the dryness of the storage environment. As this is an insulation material with a certain degree of toughness, if they come into direct contact with moisture or moisture, they will be eroded after long-term storage.

The surface groove of extruded polystyrene board is used in the kitchen decoration of hotels. The extruded polystyrene board material produced by the ceiling extruded polystyrene board manufacturer cannot be selected. Instead, aluminum buckle ceiling or integrated extruded polystyrene board material produced by the manufacturer will be chosen. The extruded board is produced using extrusion technology, so the extrusion process needs to be well controlled to ensure the production of qualified extruded boards. Secondly, the extruded plate is a combustible material, and a certain amount of flame retardant is added during the production process to prevent safety hazards during use.
