Causes of Exterior Wall Insulation and Decoration Integrated Board Leakage

exterior wall insulation and decoration integrated board will inevitably have some quality problems, especially the leakage of the facade, which will not only affect the beauty of the building, but also shorten the service life of the building if the leakage is serious. There are many reasons for the leakage of decorative panels, involving design, data, construction, use and other aspects, small make up for everyone to analyze it!

1. External forces cause plate cracking and leakage: the construction quality of external wall thermal insulation and decoration board is poor, and external forces, such as wall deformation and dislocation caused by uneven foundation settlement, and the flexibility and compatibility of each layer of data itself are not matched and poor, resulting in cracking.

2. Leakage caused by the selection of bad data: the quality of the coating used is unqualified, the ability to adapt to the deformation of the base layer is poor, and the raw materials of the surface layer are also unqualified, and there is no waterproof treatment, which makes the water absorption rate of the surface layer high, freezing and thawing will be formed in cold areas, and the plate will crack and water seepage.

3. Leakage caused by improper design and construction of detailed structure: the leeward side of the building can form a strong negative wind pressure and airflow vortex. Rainwater can climb up along the wall under the action of wind. Without any flexible sealing treatment at the junction between the plate and the base wall, it will lead to cracking.

4. Leakage caused by improper use and maintenance: when the user decorates, the hole in the outer wall is not sealed, which will make the hole leak.

5. Leakage caused by nonstandard construction: unreasonable construction process organization, unclear handover responsibility will lead to rust of the plate, damage to the external insulation layer, resulting in leakage.

, it can be seen from the above that the leakage of the external wall insulation and decoration integrated board is caused by many reasons. From the selection of raw materials for board production to the later construction and use, we must be careful and follow the correct steps to avoid the leakage problem.
