Installation of Aluminium Bifold Doors

1. Planning and Measurement

Before installation, it’s crucial to measure the opening accurately and plan the configuration of the doors. Consider factors such as the direction of opening, stacking options, and the number of panels. Professional installers can help ensure that all measurements are precise and that the doors will fit perfectly.

2. Preparation

Prepare the opening by removing any existing doors or windows and ensuring the area is clean and level. Check for any structural issues that need to be addressed before installation. It’s also important to ensure that the opening is weatherproof to prevent any potential issues with water ingress.

3. Frame Installation

Begin by installing the frame. Aluminium bifold door frames typically come in sections that need to be assembled and secured in place. Use a level to ensure the frame is perfectly straight and aligned. Fix the frame to the opening using screws and wall plugs, and apply sealant around the edges to create a watertight seal.

4. Hanging the Panels

Once the frame is in place, the panels can be hung. Start by attaching the hinges to the panels and then fix the panels to the frame. Ensure that the panels are correctly aligned and move smoothly along the track. Adjust the rollers and hinges as necessary to achieve a perfect fit.

5. Finishing Touches

After the panels are installed, check that all locks and handles are functioning correctly. Make any final adjustments to ensure the doors operate smoothly and securely. Apply additional sealant around the edges if needed and clean the glass and frames to remove any installation debris.
