How to Solve the Problem of Doors and Windows Not Closing Properly and Preventive Measures for Hardware Accessories

In daily life, aluminum alloy or PVC doors and windows often face issues such as difficulty closing properly and obstruction when opening or closing after being used for some time, which causes inconvenience. This article will explore the causes and solutions for these problems, particularly the issue of hardware accessories damage and its prevention and treatment methods.

Causes of the Problem

1. Deformation of Door and Window Frames or Sashes: Over time, the frames or sashes of doors and windows may deform due to external forces, causing them not to align properly, leading to poor sealing.

2. Loose or Detached Sealing Strips: After prolonged use, sealing strips may loosen or detach due to aging or external forces, leading to incomplete sealing of the doors and windows.

3. Damage to Hardware Accessories: The opening and closing components of doors and windows, such as pulleys, sliding brackets, and hinges, may become damaged due to prolonged use or poor quality, making it difficult to open or close the door or window properly.

4. Poor Installation Quality: If there are significant deviations during installation and timely adjustments are not made, it may cause the door or window to misalign, affecting its performance.

Preventive Measures

1. Control Installation Quality of Doors and Windows:

• The installation process should strictly follow the procedure to ensure the quality of each step.

• Ensure that the window frame and the window opening are aligned, and that the verticality, horizontality, and right angles of the frame meet the standards. Errors should be controlled within allowable limits.

2. Check the Overlap and Gaps of the Frame and Sash:

• Before the frame and sash are installed, check their diagonal measurements and flatness. After installation, check the overlap width and the surrounding gaps of the frame and sash to ensure they meet the requirements.

3. Correct Installation and Replacement of Hardware Accessories:

• Hardware accessories should be selected based on the appropriate model, specification, and performance, matching the material of the doors and windows. If any hardware accessories are found to be damaged, they should be replaced promptly.

4. Finished Product Protection and Daily Maintenance:

• Avoid external impacts, refrain from hanging heavy objects on doors and windows, and open or close them gently to extend their service life.

Causes and Prevention of Hardware Accessory Damage

Signs of Hardware Accessory Damage:

• Difficulty opening and closing, loose or detached hardware accessories, damaged pulleys or sliding brackets.

Reasons for Hardware Accessory Damage:

• The selection of inappropriate hardware accessories, or substandard quality of accessories.

• Lack of metal backing during fastening, leading to insufficient installation strength.

Measures to Prevent Hardware Damage:

1. Select Hardware Accessories that Meet Standards:

• Choose hardware accessories that meet national standards and ensure they are compatible with the material of the doors and windows. For sliding windows or double-glazed windows wider than 1 meter, use double pulleys or rolling pulleys.

2. Use Stainless Steel Sliding Bracket Hinges:

• Sliding bracket hinges should be made of stainless steel rather than aluminum alloy to improve durability.

3. Install Metal Backing Plates for Hardware Accessories:

• When installing hardware, a metal backing plate must be used, and its thickness should be greater than twice the pitch of the fasteners to ensure a firm fastening. The fasteners should not be installed on plastic profiles.

4. Correct Installation Sequence for Hardware Accessories:

• Hardware accessories should be installed after the window sash is inserted into the frame, ensuring that components such as locks and handles are positioned correctly and open and close smoothly.

5. Maintenance and Care of Hardware Accessories:

• After installation, hardware accessories should be regularly maintained to prevent rust and corrosion. During use, open and close the doors and windows gently to avoid damaging them by forcing them open or closed.

By following these measures, it is possible to effectively prevent issues such as doors and windows not closing properly and hardware accessory damage, ensuring long-term functionality and safety of the doors and windows.
