When a new house is repossessed for decoration, many people will replace the doors and windows for safety and beauty. What is the reason? Is this necessary? 1. In order to save costs, the original doors and windows used most of the raw materials used in ordinary building profiles, not to mention the poor feel, and the quality is poor. Such materials are resistant to wind pressure and are easily deformed and damaged when blown by strong winds. 2. The sound insulation and heat insulation effect of the original doors and windows is not ideal. The rubber strips are easy to age after a long time, which affects the appearance and service life, and there will be air and rain leakage. 3. The original doors and windows are not in place during civil construction or the owner's construction, causing scratches and mud fall, which are difficult to repair and clean, and affect the appearance and use of the doors and windows. 4. The color used in the original doors and windows is difficult to match with the home color system, and it does not match the style, so it needs to be replaced. accordion door for small space 3-panel sliding patio door with built in blinds cheap sliding glass doors for patio 96x80 bifold closet doors
