The corresponding solution of the external wall insulation integrated board adopts a mature product system to ensure that the insulation board is firmly bonded with the upper and lower layers of inorganic resin lining boards; special bonding mortar for waste boards is used to increase the bonding strength and meet the wind pressure requirements.
It provides the convenience of arbitrary division. Repair and replacement are quick and convenient. When the insulation decorative board is installed normally, the base layer should meet the standard plastering, no cracking, no powdering, no sanding, no hollowing, no peeling, flat surface, vertical facade, and vertical yin and yang angles.
It usually occurs on the concrete base surface to make the bonding force reliable. Refer to the on-site pull-out data for verification. Of course, in actual construction, the concrete surface needs to be treated with necessary interfaces.
In general, there is also a risk of mold growth between the existing wall and the insulation material. One solution is to install a layer of air barrier film, which can prevent hot and humid indoor air from penetrating the insulation layer. Another solution is to install an insulation material that is impermeable. To increase the firmness of the wall and avoid cracks in the corners. Newly built light brick walls should have a circle of steel bars every 50 centimeters (two bricks high), with two steel bars placed in parallel in each circle. The steel bars should be inserted into the old wall at the junction and run the same length as the new wall.
