Home door and window installation and construction precautions
Doors and windows are typically categorized into two main types: swing doors and sliding doors. Sliding doors and windows offer excellent sealing properties and take up less space, making them a popular choice based on personal preference and specific needs. In many residential buildings in our country, second-stage renovations have become common. The original interior doors often have low material quality and are not suitable for further decoration. As a result, renovating existing doors and windows is an essential part of any home improvement project.
First, Installing Swing Doors and Windows
Swing doors and windows are widely used in rooms, bathrooms, and toilets due to their good sealing performance. When installing these, it's important to start by determining the installation position using a 500mm horizontal line and a coordinate reference line from the bottom surface. This helps mark the exact location where the door or window frame will be placed.
Determine the Installation Location: 500mm Horizontal Line
Before installation, use the 500mm horizontal line and the reference line from the base to mark where the door or window frame will be installed. This ensures accurate positioning and alignment during the process.
Temporary Fixing: Correct Position
Place the door or window frame on the marked line, adjust it to the correct position, and temporarily fix it with wooden molds. Use a plumb line and level ruler to ensure it’s straight. Then, secure the frame to the wall using 100mm nails. If you're working with a brick wall, flatten the nail head before driving it into the frame. This method avoids the need to replace the entire door frame during renovation.
Fix the Door Frame: Accurate Hinge Slot Position
Once the frame is in place, measure the height and width of the door to determine the hinge slot location. After marking and cutting the slots, install the hinges on the door sash first, then attach them to the frame. Ensuring the hinge slots are accurately positioned prevents distortion after the door is fixed.
Second, Installing Sliding Doors and Windows
Sliding doors and windows consist of an upper beam and a lower rail that guides the door. The installation process involves several key steps:
Determine the Installation Location: Find the Baseline
When installing a sliding door, first locate the upper beam, side frame, and lower rail based on the 500mm horizontal line and reference lines. Secure the upper beam to the top of the opening with screws. If there’s a side frame, fix it to the wall with screws as well.
Fixed: Set the Position of the Door
Remove the hanger bolts and nuts, place the I-beam rails on the floor, and secure them to the bottom of the upper beam. Then, fix the lower rail using expansion bolts or plastic anchors for stability.
Installation: Attach the Hanger or Rail
Install the hanging bolt into the special hole at the top of the door leaf. Use a wooden block to level the door with the lower rail, then tighten the nut or screw the rail directly to the ground for support.
Inspection: Ensure Stability
Sliding doors are subject to frequent movement, so it's crucial to check each step of the installation for stability. Once the door is installed and aligned with the side frame, make sure all components are securely fastened for long-term durability.
Third, Key Construction Points for Door and Window Installation
To achieve both aesthetic appeal and functionality, attention to detail is essential during installation. Here are some important tips:
Note One: Ensure Level and Vertical Alignment
The most common method for door and window cover installation involves punching holes in the base wall and lower mold. The distance between the top and bottom of the mold should be less than 300mm, with spacing between each line under 150mm. The mold must be perfectly horizontal and vertical. If the base wall is not perpendicular, use a foundation to adjust it. Then, cut the core board according to the design and fix it with round nails to the wall and door opening.
Note Two: Secure the Bottom Plate
After confirming the bottom plate is firm and safe, apply fireproof paint. This is especially important because doors and windows are designed to provide good sealing, fire resistance, and wind protection.
Note Three: Preserve the Appearance
Choose high-quality plywood with a smooth surface and attractive pattern. Ensure the wood species matches the design requirements. When cutting the veneer, first mark the door opening and face width, then carefully cut along the line with a sharp knife. Cut the corners at a 45-degree angle, apply latex glue to the back, and attach it to the bottom plate. Finally, reinforce the surface with capless straight nails.
Note Four: Keep Seams Straight
The joints between the door opening and the wall must be straight and at a 45-degree angle. After pasting the veneer, seal the corners and handle the angles at the horizontal and vertical interfaces.
