Below are the detailed instructions for the fastest and most effective installation of composite wood-plastic doors:
Step 1. Check and re-measure the door opening – Composite wood-plastic door installation
Check if the width at 3 points (top, middle, bottom), the height at 2 points (left, right), and the wall thickness are consistent. A spirit level or laser level can be used to check the vertical alignment of the door opening. The standard size of the door opening determines whether the composite wood-plastic door installation will be successful. If the door opening has defects such as tilting, warping, uneven walls, or dimensions outside the tolerance, the installation team must immediately report to the responsible person for a solution.
The advantage of Naviwood composite wood-plastic doors is their ability to accommodate large tolerances in door openings thanks to smart architraves that can adjust in size. The tolerance for door openings during composite wood-plastic door installation is approximately +20mm for width and +20mm for height.
Step 2: Secure the shims (blocks) to both sides of the door opening:
Shims, also known as blocks, are made from high-grade wood-plastic, offering water resistance, strength, and good screw retention. Shims act as an intermediary, connecting the door frame to the wall, and directly impact the stability of the door unit after complete installation.
Depending on the sturdiness and structure of the wall, different types of screws will be used by the installation personnel.
- For walls with a stable structure, use expansion anchors to directly fasten the shims to the wall.
- For drywall, use self-drilling screws for reinforced steel frames.
- For wooden frames, use wood screws.
Step 3: Install the frame into the wall
Install the two vertical frame components first, followed by the horizontal frame component. The vertical and horizontal frame components must be precisely measured and cut according to the actual installation dimensions. For doors installed in bathrooms, the composite wood-plastic door installation personnel must pay attention to cutting the frame base to fit the stone threshold, if any. This small detail ensures aesthetics as well as tightness, preventing gaps where insects could nest. Then, connect the frame to the shims already attached to the wall with screws.
Connect the vertical and horizontal frame components as shown below
METHOD FOR THROUGH-FRAME SCREW INSTALLATION:
- Place the shim behind the door frame, press the door frame against the wall, then drill through the door frame and the shim. Insert an expansion anchor and tighten the door frame (similar to installing a regular aluminum door).
- Use a 10mm flush screw cap to cover the screw holes for a neat finish.
Use foam sealant to fill any gaps between the door frame and the wall (if present).
Step 4: Install hinges on the door leaf and attach the leaf to the frame
For typical single-leaf doors, install 3 mother-and-child hinges on the leaf. The positions of the 3 mother-and-child hinges are 200mm, 800mm from the top of the leaf downwards, and 250mm from the bottom of the leaf upwards. Prop and secure the leaf to the frame, ensuring a 3mm gap between the frame and the leaf, and a 5mm gap between the leaf and the floor.
Step 5: Install the architrave on the door frame
Calculate the length of the architrave pieces and cut them at a 45-degree angle. Connect the architrave to the frame via its clip-on foot. Use silicone sealant to cover any gaps between the architrave and the wall. Similar to the door frame, for bathroom doors, the composite wood-plastic door installation personnel must pay close attention to notching the architrave to fit snugly against the stone threshold.
Step 6: Install the door lock and other wooden door accessories
To ensure absolute precision, the lock hole on the door leaf has been pre-drilled and routed at the factory. The technician proceeds to install the lock cylinder, lock body, lock faceplate, and handles on the leaf. Next, mortise and install the strike plate into the frame. Test the lock, open and close the door to check the alignment between the latch and the strike plate.

Step 7: Final cleaning.
Perform a final inspection of the door unit before cleaning and handing it over to the customer. Use a damp cloth with clean water to wipe away any dust accumulated around the door frame.
