The service life of the integrated exterior wall insulation project is not less than 25 years, and there is a lack of corresponding durability and weather resistance test data support. The exterior wall insulation system does not have a data model for the stress, strain, deformation and change trend of each structural layer and material performance over time.

The stress, strain, deformation and change trend of the integrated exterior wall insulation over time

The integrated exterior wall insulation system and the main wall of the exterior wall filling wall should be designed according to the ordinary plastering method of the exterior wall. It is advisable to use anti-cracking plastering mortar with a thickness of generally 20mm. The strength verification of the composite insulation formwork should consider the standard value of the measured pressure of the newly poured concrete on the formwork. Before the integrated exterior wall insulation construction, the reference line and the control line should be hung according to the design size of the exterior facade of our house and the requirements of the external insulation technology. Hang vertical lines at the corners of the exterior wall of the building and other necessary parts, and hang horizontal lines appropriately on the floors.

According to the building facade design and the requirements of the external wall insulation technology, the horizontal and vertical control lines and telescopic lines, decorative seams, etc. of the external doors and windows are popped up on the wall. Paste the flip mesh cloth. All exposed areas on the side of the polystyrene board should be covered with mesh cloth.

The task of the exterior wall waterproofing project is to comprehensively evaluate the above factors, select waterproof materials that meet quality standards, and carry out scientific, reasonable and economical design to meet the waterproof durability and use function of the building (structure). Before the exterior wall waterproofing work, the base must be dry, clean and flat, so it is necessary to conduct a comprehensive inspection of the base and fill the concrete defects and construction joints. The wall base of the exterior wall must be clean and flat to ensure it.

It is generally recommended to do exterior wall insulation. The reason is simple, that is, the materials, construction and cost of integrated exterior wall insulation are cheaper, especially in terms of construction. Exterior wall insulation can not only be installed in newly built houses, but also repair old houses that have been built for many years.
