High-Performance Aluminium Bi-Fold Doors

If you’re looking to flood your home with daylight and create an effortless indoor-outdoor flow, aluminium bi-fold doors are the ultimate architectural feature.

Designed to fold away neatly when open and offer panoramic views when closed, bi-folds are one of the most popular home improvement choices for contemporary kitchens, dining spaces, and garden extensions.

At LB Supplies, we supply market-leading Korniche bi-folding doors engineered for strength, security, and weather resistance. Made from lightweight yet ultra-durable aluminium, our bi-fold doors feature slim sightlines that maximise glass area without compromising structural integrity.

Why Choose Our Bi-Folding Doors?

Choosing the right external door system is crucial for safety, thermal comfort, and style. Here is why homeowners and tradespeople trust LB Supplies for their bi-folds:

  • Exceptional Thermal Efficiency: Engineered with advanced thermal break technology and high-spec double glazing to retain heat in winter and keep your home cool in summer, helping lower energy bills.
  • Uncompromised Home Security: Our aluminium bi-fold doors feature high-security multi-point locking systems, shootbolts, and anti-drill cylinders to keep your property protected against intruders.
  • Smooth Glide Operation: Heavy-duty rollers and precision-engineered tracks ensure that opening and closing your bi-folds feels completely effortless every time.
  • Sleek, Modern Aesthetics: Slim aluminium profiles mean less frame and more glass, creating a clean aesthetic that complements both modern architecture and classic brickwork.
  • Weatherproof & Low Maintenance: Built to withstand harsh British weather, our bi-folding door frames are powder-coated to prevent rust, fading, corrosion, or warping.

Versatile Configurations: 1 to 7 Sash Options

Every home is different, which is why our bi-fold doors come in a full range of panel configurations to fit any opening size:

  • 1 & 2 Sash Bi-Folds: Ideal for compact openings, utility rooms, or replacing standard single/french patio doors.
  • 3 & 4 Sash Bi-Folds: The standard choice for medium-sized patio openings, offering flexible traffic door options for everyday access.
  • 5, 6 & 7 Sash Bi-Folds: Perfect for expansive house extensions and large wall openings, opening up an entire side of your house to the outdoors.
