Below are 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 measurements at the top, middle, and bottom for width, and the left and right sides for height, as well as the wall thickness, are uniform. A level or laser level can be used to check the vertical alignment of the door opening. A standard door opening size is crucial for ensuring proper installation of wood-plastic doors. If the opening has defects such as tilting, warping, uneven walls, or if the dimensions are outside the tolerance, the installation team must immediately report it to the person in charge to find a solution.
The advantage of Naviwood wood-plastic doors is their ability to accommodate large tolerances in door openings thanks to smart trim that can adjust dimensions. The tolerance for door openings during the installation of wood-plastic doors is approximately +20mm for width and +20mm for height.
Step 2: Secure the shims (blocks) to both sides of the door opening wall:
Shims, also known as blocks, are made of high-quality wood plastic, offering water resistance, strength, and good screw retention. The shims act as an intermediary to connect the door frame to the wall, directly affecting the stability of the entire door unit after complete installation.
Depending on the strength and structure of the wall, the installer will use different types of screws.
- For stable wall structures, concrete nails are used to directly secure the shims to the wall.
- For weaker wall structures, technicians will use D8x100 lag screws.
- For gypsum board walls with reinforced steel frames, self-drilling screws are used.
- For wooden frame walls, wood screws are used.
Step 3: Install the frame into the wall
Install the two vertical frame members first, then the horizontal frame member. The vertical and horizontal frame members must be accurately 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 bottom of the frame to accommodate any stone thresholds. This small detail ensures both aesthetic appeal and tight sealing, preventing gaps where insects could nest. Then, connect the frame to the pre-attached shims on the wall with screws.
Connect the vertical and horizontal door frames as shown below
METHOD OF INSTALLING SCREWS THROUGH THE DOOR FRAME:
* Use a block placed behind the frame, press the frame firmly against the wall, then drill through both the frame and the block. Insert an expansion anchor and tighten the frame (similar to installing regular aluminum doors).
* Use 10mm recessed caps to cover the screw holes for a clean finish.
Step 4: Install hinges on the door leaf and attach the leaf to the frame
For a standard single-leaf door, install 3 parent-child hinges on the door leaf. The positions of the 3 parent-child hinges are 200mm and 800mm from the top of the leaf downwards, and 250mm from the bottom of the leaf upwards. Prop and attach the door 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 trim on the door frame
Calculate the length of the trim pieces and cut them at a 45-degree angle. Connect the trim to the frame using the trim's clips. Use silicone sealant to fill any gaps between the trim and the wall. Similar to the door frame, for bathroom doors, the composite wood-plastic door installation personnel must pay close attention to cutting the trim to fit snugly around any stone threshold.
Step 6: Install the door lock and other wooden door accessories
To ensure absolute accuracy, the lock hole on the door leaf is pre-drilled at the factory. The technician proceeds to install the lock cylinder, lock body, strike plate, and handles on the door leaf. Next, carve and install the strike box into the frame. Test the lock, opening and closing the door to check the alignment between the latch and the strike box.

Step 7: Final cleaning.
Perform a final check of the door set before cleaning it for handover to the customer. Use a damp cloth with clean water to wipe away any dust adhering to the door frame. The finished wood-plastic door handed over to the customer should still have its protective plastic wrapping intact.
