Choosing a high-quality wooden door is essential, but the installation process plays just as critical a role in ensuring long-term performance and aesthetics. Whether you're installing a new door or replacing an old one, following proper installation standards can make all the difference. Here are key guidelines to help you achieve a professional finish:
1. Door Panel Installation
- The door panel should be securely attached with no visible gaps or misalignment. All fixed parts must be properly fastened.
- The diagonal measurement of the door panel must be accurate. For panels under 2 meters, the tolerance should be less than 1 mm. For longer panels, the tolerance increases to 1.5 mm.
- After installation, the door should be perfectly vertical and horizontal. Vertical alignment should not exceed +2 mm, while horizontal straightness should stay within +1 mm.
- The door panel must be secured using at least three screws per side. A metal plate should also be installed for added stability. The gap between the panel and the wall should be filled with foam rubber on both sides, ensuring even coverage and a smooth finish after drying.
2. Trim Installation
- The trim should be evenly glued to both the door panel and the wall. The joints should be flat and seamless. On the same side, the trim should lie in a single plane.
- If the wall is uneven, the trim must still align properly. Any curvature in the trim should not exceed 1 mm. A sealing strip should be applied along the gap between the trim and the wall for a clean look.
3. Door Leaf Installation
- Once installed, the door leaf should be flat and vertical. It should align perfectly with the exposed surface of the door frame.
- The door should open and close smoothly without any unusual noise. The clearance between the door and the frame should be 6 mm on the bottom and 2 mm on the other sides, with a tolerance of ±0.5 mm.
- When closed, the door should fit tightly against the seal strip and remain stable without wobbling.
4. Hardware Installation
- Hinges must be aligned vertically and horizontally. The hinge slots should match the size and shape of the hinges precisely, with a tolerance of ±0.5 mm. The seams should be smooth and tight, and the hinges should open and close easily.
- The door lock cutout must be accurate and consistent with the lock body and strike plate. The lock should operate smoothly without any noise. All hardware components should be fully installed and secured with properly tightened screws.
- Accessories such as door closers, handles, and latches should be placed in their designated positions. They should be firmly attached, with all screws properly inserted and hidden within the hardware for a neat appearance.
5. Final Appearance
- The gap between the door frame and the trim should not exceed 3 mm. This gap should be sealed with a waterproof sealant to prevent air leaks and moisture damage.
- After installation, the entire door should be level, functional, and visually appealing. There should be no scratches or imperfections that could affect its appearance or durability.
By following these detailed steps, you can ensure a high-quality wooden door installation that not only looks great but also functions efficiently for years to come.
