Profile Pvc folding treatment method and function at door and window openings

Now the most commonly used material in construction engineering is Angelica Profile Pvc. Pvc Corner is more and more widely used in energy-saving insulation buildings. In the construction of exterior wall insulation, exterior wall insulation Profile Pvc is often required for folding treatment, but you must not know that Profile Pvc is actually Profile Pvc. Next, let's take a look at the folding treatment method and function of Pvc Corner at door and window openings!

Profile Pvc folding refers to the yin and yang corners of the exterior wall. When the Pvc Guards is overlapped, the Profile Pvc on both sides should be turned over the yin and yang corners by 10cm (overlap width 20cm) to ensure that there is no cracking at the corners of the exterior wall. At the expansion joint, first remove the foam board, then press the Profile Pvc on the exterior wall side, and then cover the expansion joint with a cover plate at the expansion joint. Note that the cover plate should cover the press edge.

How to wrap the Pvc Guards around doors and windows: stick a piece of alkali-resistant Profile Pvc (dotted line) on the wall, paste the insulation board and then wrap the corner bit around it. Because the window is easy to crack, this will increase the connection between the board and the wall. Some windows need to be pulled diagonally to prevent cracking at the corners. Then pay attention to the arrangement of the boards. The board should be cut into a knife handle shape at the corner. The joint cannot be placed at the corner of the window. This is the specification for insulation.

The positions such as the door and window openings are where the corner bit is not continuous. The discontinuous positions of the exterior wall Profile Pvc are prone to stress concentration and cracks. The broken ends of the Profile Pvc on the large wall need to be overlapped, so it is also necessary to overlap at the door and window openings. Wrapping can solve the problem of Profile Pvc overlap and reduce stress concentration. In addition, the door and window positions are easily damaged by external forces. Wrapping the Profile Pvc can enhance the local strength of insulation to a certain extent.
