Fitting a Bi-Folding Door

You’ve probably noticed that bifold doors or, more specifically, aluminium bifold doors are becoming a bit of a trend in people’s homes nowadays.

Aluminium bifold doors are a stylish, versatile solution for residential and commercial properties, seamlessly merging indoor and outdoor spaces while maximising natural light.

They offer an elegant, modern aesthetic while remaining durable, low-maintenance, and energy-efficient.

This guide covers the essentials of installing aluminium bifold doors, including planning, step-by-step instructions, and tips for achieving a flawless result. Follow along to enhance your space with these high-quality, functional doors.

Benefits of Aluminium Bifold Doors

Choosing aluminium bifold doors comes with a multitude of advantages. Here’s why they’re an ideal choice for many home and business owners:

1. Durability and Longevity
   Aluminium is highly durable and resistant to corrosion, ensuring these doors withstand harsh weather conditions without warping, rotting, or fading. This resilience makes them a long-lasting choice for any property.
2. Aesthetic Appeal
   Aluminium bifold doors feature slim frames that create an expansive glass area, enhancing natural light and providing unobstructed views. Their sleek, modern design complements both traditional and contemporary aesthetics.
3. Energy Efficiency
   With thermally broken frames and high-performance glazing, aluminium bifold doors reduce heat transfer, helping to maintain comfortable indoor temperatures year-round. This energy efficiency translates to lower energy bills and a smaller carbon footprint.
4. Low Maintenance
   These doors require minimal upkeep. A quick wipe-down with mild detergent is usually enough to keep the frames clean and looking new. The robust material resists scratches, dents, and other common forms of damage.

Preparing for Aluminium Bifold Doors Installation

Proper planning is key to ensuring a smooth installation process. Below are the steps to prepare for installing aluminium bifold doors.

Step 1: Measuring the Opening

Accurate measurements are key to a successful installation. Here’s how to measure effectively:

• Width and Height
  Measure the width and height of the opening at multiple points (top, middle, and bottom for width; left, centre, and right for height). Use the smallest measurements to ensure a snug fit.
• Depth Check
  Ensure the wall depth can accommodate the door frame. This is particularly important for retrofit projects in older buildings where walls might differ from standard depths.

Step 2: Choosing the Right Door Configuration

Aluminium bifold doors come in various configurations, ranging from two-panel to multi-panel systems. The panel count and opening direction (inward or outward) depend on the space and desired functionality.

• Panel Count
  More panels offer a wider opening but require additional space when folded. Select the panel count based on the door width and layout.
• Opening Mechanism
  Consider inward or outward opening, depending on indoor or outdoor space limitations. Outward-opening doors preserve indoor space, while inward-opening doors work well in large rooms with sufficient clearance.

Step-by-Step Guide to Installing Aluminium Bifold Doors

With the preparation complete, you can begin the installation process. Follow each step meticulously for a secure and reliable setup.

Step 1: Prepare the Workspace

Before you start, clear the area around the opening and ensure it’s level and structurally sound.

• Remove Debris
  Any dust, dirt, or old caulking around the frame area can impede the new installation. Use a damp cloth to clean the space thoroughly.
• Check Level and Square
  Using a spirit level, check that the opening is level and square. Misalignment can affect the door’s functionality, so adjust the surface as needed with shims or levelling compounds.

Step 2: Install the Door Frame

The door frame provides structural support and needs precise alignment for smooth operation.

• Position the Frame
  Place the frame into the opening, ensuring it’s centred and level. A secure frame is vital for easy door movement and longevity.
• Secure with Screws
  Use appropriate screws to attach the frame to the wall studs. Start at the top, moving to the sides and bottom to prevent twisting or bending.
• Check for Leveling
  Confirm the frame is level in all directions using a spirit level. Make any necessary adjustments to prevent operational issues later.

Step 3: Hang the Door Panels

The panels are the moving components of bifold doors, so careful installation ensures they slide smoothly.

• Attach the Top and Bottom Hinges
  Attach the hinges to the designated slots on each panel. Follow manufacturer guidelines for hinge placement to ensure stability and smooth folding.
• Install Each Panel Sequentially
  Start with the panel closest to the frame, connecting it to the hinges and sliding mechanisms. Add subsequent panels, ensuring each one aligns properly.
• Test Movement
  After hanging all panels, open and close the doors to confirm smooth movement. Adjust hinges as necessary to prevent sticking or misalignment.

Step 4: Secure and Adjust the Locking Mechanism

The locking mechanism is essential for security and functionality. Install and adjust it carefully.

• Install Lock Cylinder
  Insert the lock cylinder into the designated slot on the lead panel. Secure it with screws, ensuring it operates smoothly.
• Align Strike Plate
  Attach the strike plate on the frame, aligning it with the lock mechanism. Test the lock multiple times to confirm a secure, flush fit.

Finishing Touches for Aluminium Bifold Doors

After installing the frame, panels, and lock, finish the installation by sealing and adjusting.

Seal the Edges

Proper sealing prevents water ingress and enhances insulation.

• Use Weatherproof Sealant
  Apply weatherproof sealant around the frame's exterior edges. This prevents drafts, water leaks, and heat loss, making the installation energy-efficient and weather-resistant.
• Seal Inside Joints
  Add sealant to any visible gaps inside the frame to further insulate the doors, enhancing energy efficiency and comfort.

Install Trims and Covers

Cover visible screws and framing edges to give the installation a polished look.

• Attach Decorative Trims
  Aluminium trim pieces can be added around the frame for a clean, professional finish. Secure them in place with adhesive or screws, depending on the type.
• Install Cover Caps
  Place cover caps on visible screws to improve aesthetics and prevent moisture from corroding the hardware.

Final Adjustments and Cleaning

• Inspect Movement and Locking
  Test the doors’ movement and lock mechanism to confirm smooth, secure operation. Tighten any screws or adjust hinges as needed.
• Clean Glass and Frame
  Wipe down the frame and glass panels with a non-abrasive cleaner to remove fingerprints or installation residue.

Maintaining Aluminium Bifold Doors

Regular maintenance ensures your aluminium bifold doors remain in optimal condition.

Cleaning the Frames and Glass

• Frame Cleaning
  Use a soft cloth with mild detergent to clean the frames every few months. Avoid harsh chemicals, which may damage the aluminium’s finish.
• Glass Panels
  For glass cleaning, use a gentle, ammonia-free cleaner to prevent streaking or residue.

Lubricating Hinges and Tracks

Regular lubrication minimises wear and tear on moving parts.

• Hinge Maintenance
  Apply a silicone-based lubricant to the hinges biannually. Avoid petroleum-based lubricants, which can attract dust and grime.
• Track Lubrication
  Keep tracks free of debris and use a dry lubricant periodically to ensure smooth sliding.

Inspecting Seals and Weatherstripping

Inspecting seals prevents drafts and energy loss.

• Check Weatherstripping
  Examine the weatherstripping around the frame to confirm it’s intact. Replace any damaged sections to maintain insulation.
• Reapply Sealant if Needed
  If you notice any cracks or gaps in the sealant, reapply to maintain weather resistance.
