The overall insulation decorative panel is not simple, today I will introduce the detailed process of insulation decorative panel. When the size of either side of the circuit board is less than 300mm, it can be symmetrically fixed on the long side. When the parallel dimension on both sides of the veneer is greater than 300mm, all sides of the veneer must be fixed. The flatness of the installation of the overall insulation decorative panel should be checked with a 2m ruler and a feeler gauge, and should be less than mm. The installation verticality of insulation decorative panels should be checked with a 2m ruler and a feeler gauge, and should be less than 2mm. The installation height of the insulation decorative panel should be less than 1mm when checked at a height of 1m.

Add an appropriate amount of water, stir into a paste, and then apply directly onto the treated wall. After using twice, press Polish. After completely drying, apply glue and stick glass and solder mesh tape, then you can start wall work such as scraping putty. The installation process is carried out according to the layout: economical, beautiful, and safe. The thickness of polymer mortar shall not exceed 4, and the first layer shall not exceed 5. The insulation decorative panel is fixed to the wall with specialized fasteners. After the completion of thermal insulation decoration, the space between adjacent panels will be filled with thermal insulation foam strips to further maintain heat and save silicone weather sealant.

After pasting the entire insulation decorative panel onto the wall, it is necessary to drill holes on the insulation panel and install insulation nails that match the insulation panel. One end is a circular nail, and the other end is a plastic expansion bolt, which fixes the insulation board to the wall. Usually, the insulation board on the wall should have no less than 6 insulation nails per square meter. During installation, it must be tightened with a screwdriver. Do not use a hammer directly, otherwise the effect of the expansion bolt will be ineffective. Before installation, the position should be determined and the insulation material should be firmly fixed. Special anchoring means that both insulation materials and panels can be protected simultaneously. Use a ruler to lean against the surface of the plywood, and then measure the gap with the ruler. Use a small wooden hammer to strike the surface of the board, and then determine the size of the bonding area and the number of bonding points based on the firmness of the hollow drum.

When the dimensions on both sides of the circuit board are less than 300mm, it can be symmetrically fixed on the long side. When the parallel dimensions on both sides of the veneer are greater than 300mm, all sides of the veneer must be fixed. When installing insulation materials, special attention must be paid to closing special components. For example, please pay attention to the leak proof edge of the window, the aesthetics of the window edge, and the possibility of large-scale installation.

The commonly used exterior wall insulation material technology is the foam board after the completion of the wall structure. Due to the poor bonding quality of mortar, the fire resistance of this insulation material is low, the surface layer is heavy, and it is prone to detachment and cracking. In addition, the construction period of ordinary external insulation layers is long and the safety is poor. In addition, due to insulation materials not meeting Class A fire prevention standards, it is easy to cause serious problems such as fires, which seriously endanger people's lives and property safety.
