The external wall insulation technology has been applied for a long time, and there is no project without quality problems. Considering the safety hazards in current external wall insulation, attention should be paid to the quality of insulation materials. Insulation materials must continue to innovate and improve their performance. They must not only be efficient and energy-saving, but also safe and durable. Only through continuous development can we constantly improve.

Refuse to use "three no" products to ensure material quality. Secondly, it is necessary to strengthen professional training on the construction of rock wool exterior wall insulation system, reduce the problem of falling caused by non-standard construction, and ensure the professionalism of construction. When the decorative layer of the external insulation system uses decorative bricks, vertical separation joints not exceeding 12m and horizontal separation joints not exceeding 6m should be provided, and the width of the joints should not be less than 6mm. Use soft waterproof materials for seams to ensure that the surface layer does not leak. The diameter of galvanized steel wire mesh used for external wall insulation shall not be less than 0.9mm, and the mesh size shall be 12.7 × 12.7mm.

Of course, buildings have high requirements for the various materials used. If only insulation boards are used, overall decoration cannot be carried out and various defects will eventually appear. Therefore, when using insulation decorative panels, the purpose of building insulation is achieved. Moreover, it is very lightweight, of high quality, and easy to install during the construction process. It has the characteristics of anti cracking, no peeling, and no permeability. This not only reduces the burden on buildings, but also mitigates many potential safety hazards.

The external insulation of the exterior wall is not simple. Today, I will provide you with a detailed introduction to the processing technology of thermal insulation decorative panels. Therefore, the risk of cracking, deformation, and damage to the main wall is greatly reduced, and the service life is greatly extended.

During the construction process, if the base layer is not cleaned, the construction personnel will deviate from the standard, and the verticality and flatness will be insufficient. If the thickness of the mortar is directly increased to adjust the flatness, uneven thickness will directly lead to cracking. The spray molding speed of polyurethane foam plastic is fast, and it is not easy to produce a flat spray effect. Uneven distribution is normal. Insulation can relax the flatness, but poor flatness of drainage ditches can affect drainage speed. Therefore, it needs to be used in combination with other waterproof materials.
