Exterior wall insulation mesh cloth turning and disposal construction
Before pasting the benzene board on the exterior wall insulation mesh, turn over the mesh at the end of the insulation layer. Apply 70mm wide and 2mm thick polymer mortar to the parts that need to be turned over. Quickly cover one end of the mesh with 70mm steel. Apply and press into the polymer bonding mortar until the overflowing polymer bonding mortar covers the mesh cloth and stops leaking. The remaining part is wrapped up for use. The length of the thrown-out part is exposed on the board surface around the end of the board. The part should be no less than 100mm, and the finished mesh should be protected by turning or covering it.
The effect of turning over the exterior wall insulation mesh cloth
1. Positions such as door and window openings are where the mesh cloth is discontinuous. The discontinuous positions of the mesh cloth are prone to stress concentration and cracks. If the mesh cloth is broken on a large wall, it needs to be overlapped, so it also needs to be overlapped at the door and window openings. Connected, the mesh cloth overlapping treatment can solve the problem of mesh cloth overlap and reduce stress concentration;
2. Doors and windows are easily damaged by external forces. Turning the mesh cloth over and over can enhance the strength of the thermal insulation to a certain extent;
3. The mesh cloth turning and wrapping process is also helpful to protect the insulation layer boundary.
During the construction of exterior wall insulation, we often need to turn over the mesh cloth. So how do you turn the bag? What is the effect of mesh bag turning?
Insulation mesh cloth bag disposal construction
Before putting up the styrene board, turn over the mesh cloth at the cut off part of the insulation layer. Apply 70mm wide and 2mm thick polymer mortar to the part that needs to be turned over. Quickly press the 70mm end of the mesh cloth into the polymer adhesive with a steel trowel. In the bonded mortar, press until the overflowing polymer bonding mortar covers the mesh cloth and stops leaking. Wrap up the remaining part for use. The length of the thrown-out part should be no less than 100mm around the end of the board and the part exposed on the board surface. The finished mesh should be protected by flipping or covering it.

Why is it necessary to post a fold-over mesh cloth on the openings of exterior wall insulation doors and windows?
1. Locations such as door and window openings are where the mesh cloth is discontinuous. The disconnected locations of the mesh cloth are prone to stress concentration and cracks. If the mesh cloth is broken on a large wall, it needs to be overlapped, so it is also required at the door and window openings. Overlapping and overlapping bags can solve the problem of mesh overlap and reduce stress concentration.
2. The positions of doors and windows are easily damaged by external forces. Turning over the mesh cloth can enhance the strength of the insulation to a certain extent. 3. Turning over the bags is also conducive to protecting the boundaries of the insulation layer.
The primary purpose of applying mesh cloth is to prevent cracks between the insulation layer and the wall.
