1. During the renovation, since the window removal process will destroy the interior and exterior walls, it is better to replace the doors and windows before proceeding with the next step of renovation. The owner should specify which brand of profile to use, because the quality of the profile will determine the quality of the entire door and window, sealing and resistance to aging, and buyers should not be fooled by the vague concept of "low-cost plastic doors and windows" in the market.
2. When purchasing, it is necessary to go to the formal building materials market. The roadside stalls are not easy to process and the accuracy and strength cannot be guaranteed. Especially the plastic doors and windows they make, the inner lining steel is of poor quality, even without lining steel, and other accessories are also very poor.
3. The appearance of plastic doors and windows should be blue-white. The color is too pale or gray, indicating that the stable ingredients in the material are not enough.
4. Check if the hardware is flexible and smooth.
5. The sliding window of the window frame should have aluminum slides to facilitate replacement.
6. The sealing strip of the casement window should be freely replaceable because the sealing strip has a shorter life than the form.
7. The push-pull window and the seal of the window sash should be fixed in the middle, which is the key to the sealing of the sliding window.
8. During the installation process, the horizontal and vertical alignment of doors and windows should be supervised. The styrofoam is used for filling between the window frame and the wall, and the inside and outside of the window frame must be sealed with silicon copper glue or sealant to prevent water seepage. After installation, the protective film must be removed. Otherwise, the service life of the doors and windows will be reduced.
