Correct installation method of windows

The correct installation method of windows includes the following steps:

1. Measuring size: Before installing the window, it is necessary to measure the size of the window to ensure that the window matches the size of the wall opening.

2. Preparation: Clean up the gypsum, paint and other sundries around the window. Check whether the wooden frame is rotten or damaged and repair it.

3. Install waterproof membrane: coat the wall with waterproof membrane to prevent moisture from penetrating into the room.

4. Place windows: Place windows at the opening and make sure they are vertical and horizontal. Support with a wedge.

5. Fix the window: Fix the window on the wall with nails or screws. Make sure all four corners are firmly fixed.

6. Gap filling: Fill the internal and external gaps with silica gel or foam to ensure the sealing performance.

7. Test operation: Test whether the window can be opened and closed, and check whether the sealing performance is good.

Please note that before any installation work, please read the installation instructions provided by the manufacturer carefully and follow the instructions. If you are not sure how to install windows, please seek advice and help from professionals.
