Many buyers overlook these follow-up steps:
Waterproofing and Sealing: Choose weather-resistant waterproof sealant for windows, especially silicone sealant for surfaces exposed to direct sunlight.
Hardware System: Window hardware directly affects lifespan; hinges are recommended to be made of 304 stainless steel.
Auxiliary Accessories: Installation locations for items such as retractable screens and security grilles need to be planned in advance.
