Bifold doors have become one of the biggest home improvement trends in the UK in recent years. Across London, Surrey and beyond, more and more homeowners are choosing these stylish doors to transform their living spaces. From Victorian terraces to modern apartments, these versatile doors are changing how we use our homes.

Bifold doors have moved from being a luxury choice to an essential feature that many homeowners now prioritise when renovating or extending their properties. If you haven’t considered them, now might be the time to see what everyone’s talking about.

At Aim Windows, we’ve installed premium bifold doors for homeowners across London, helping them make the most of their living spaces while adding value to their properties.

What is a Bifold Door?

Bifold doors are made up of multiple glass panels that fold back concertina-style along a track. They maximise natural light and views, and when fully opened, they create a wide, unobstructed doorway that connects indoor and outdoor spaces.

What Makes Our Bifold Doors Great?

At Aim Windows, we specialise in high-quality aluminium bifold doors that combine style, functionality, and durability. Here’s why our bifold doors stand out from the crowd:

Sleek, Slim Frames

Our aluminium bifold doors feature exceptionally slim frames that:

  • Allow larger glass panels with fewer frames to interrupt your view
  • Let more natural light flood into your home
  • Create a contemporary, streamlined appearance

The slender profile of our frames creates a modern look that works beautifully in contemporary homes but can also add a modern touch to traditional homes. When closed, they offer clean lines and maximum glass area; when open, they fold neatly away to maximise your space.

Durability

Our bifold doors are built to last, with:

  • A lifespan of up to 40 years with minimal maintenance
  • Powder-coated finishes that resist scratches and fading
  • Weather-resistant properties that stand up to the British weather

This exceptional durability means your investment will keep performing and looking good for decades. They also require virtually no maintenance, staying fresh without the hassle of regular upkeep that other door materials might require.

Superior Thermal Performance

Our bifold doors feature advanced thermal break technology that prevents heat from escaping your home:

  • U-values as low as 1.5 W/m²K
  • Excellent draught-proofing
  • Options for double or triple glazing

These thermal properties ensure your home stays warm in winter and cool in summer, helping to keep energy bills down while maintaining a comfortable living environment.

Flexible Design Options

We make our bifold doors to measure and offer extensive customisation:

  • Available in any RAL colour to match or complement your home
  • Metallic, textured, and woodgrain finishes available
  • Dual colour options (different colours inside and out)
  • Choice of internal or external fold configurations
  • Various hardware options to complete the look

Whether you want a statement door or something more subtle, we can create bifold doors that perfectly match your vision and style.

Quality Components

We only use the best components in our bifold door systems. The central part of this is the Korniche Aluminium Bifold Door System, widely recognised for its exceptional quality and performance. This premium system forms the foundation of our doors, ensuring reliability for years to come.

We complement these superior frames with high-security hardware from trusted names like Yale, Ultion, MILA, and Winkhaus. Our doors feature multi-point locking mechanisms for strong security, while precision-engineered rollers, hinges, and drop bolts ensure smooth, effortless operation every time you use them. All these quality elements work together to create bifold doors that are reliable, secure, and weather-resistant.

Professional Installation

We handle the entire process of adding bifold doors to your home, from the initial survey to the installation:

  • Our surveyors are IQ Level 3 NVQ Certified in Fenestration
  • We never use subcontractors – we directly employ all our fitters
  • We provide comprehensive insurance-backed guarantees
  • Our experienced team ensures a perfect fit and finish

With years of experience installing bifold doors across London, our team consistently delivers exceptional results.

Why Aluminium is the Best Material for Bifold Doors

While bifold doors can be made from different materials, we choose aluminium as it offers significant advantages that make it the ideal choice:

Strength and Stability

Aluminium’s inherent strength allows for:

  • Slimmer frames that maximise glass area and views
  • Larger door panels that wouldn’t be possible with other materials
  • Better structural integrity, preventing warping or sagging over time
  • Smooth operation even with large glass panels

Design Flexibility

The versatility of aluminium means:

  • It can be powder finished in any RAL colour
  • It can accommodate various configurations and opening styles
  • It works well with both contemporary and traditional architecture

Sustainability

Aluminium is an environmentally responsible choice:

  • It’s 100% recyclable with no loss of quality
  • It has an exceptionally long lifespan, reducing the need for replacement
  • It requires minimal maintenance, saving resources over time

For these reasons, we’ve chosen to specialise in aluminium bifold doors, offering London homeowners the very best in terms of quality, appearance, and performance.
