**Common Causes of Hardware Damage in Doors and Windows**
Hardware damage often stems from a combination of poor design, substandard materials, and improper installation. One of the main issues is the use of low-quality or mismatched hardware accessories. When choosing hardware, it's essential to ensure that it meets national standards and is compatible with the specific type of plastic doors and windows being installed. Another common problem is the lack of proper support during installation—such as not using metal liners when tightening Screws, which can lead to weak fixation and eventual loosening.
When hardware components like pulleys, sliding hinges, or handles become loose or fall off, it can significantly affect the performance of the door or window. This not only causes inconvenience but also reduces the lifespan of the entire system. In many cases, the issue arises because installers skip critical steps, such as using non-metallic linings or fastening directly into plastic profiles, which are not strong enough to support the hardware over time.
**Preventive Measures to Protect Hardware Accessories**
To avoid these problems, it’s crucial to follow best practices during both selection and installation. First, always choose hardware that complies with current regulations and is specifically designed for the type of doors and windows you're working with. Second, when installing hardware, make sure to use metal liners. These should be at least twice as thick as the screws used, providing a solid base and preventing the hardware from loosening. Avoid using non-metallic materials or fastening directly into plastic profiles, as this can compromise the integrity of the installation.
Another important step is to install the hardware last. For example, locks and handles should be attached after the window sash is properly positioned within the frame. This ensures accurate alignment and smooth operation. After installation, regular maintenance is key. Keep hardware clean and dry to prevent rust and corrosion. Also, avoid slamming doors or windows shut—gentle handling will help maintain the functionality of the hardware for years.
For larger windows, especially those wider than 1 meter, or for double-glazed doors and windows, it's recommended to use dual pulleys or roller-type systems to distribute weight evenly and reduce wear. Additionally, sliding hinges must not be made from aluminum alloys due to their lower durability. Instead, stainless steel should be used to ensure long-term strength and resistance to environmental factors.
By following these guidelines, homeowners and installers can significantly extend the life of their doors and windows while maintaining optimal performance and safety.
