Bring the outside in with Aluminium bi-fold doors!

Our bi-folding products provide a seamless view of the outdoors. Manufactured from quality materials and expertly fitted by our qualified installers, our Sheerline aluminium bifold doors are our most popular option and with good reason; because of aluminium’s natural strength, they can be built with ultra-slender sightlines, resulting in a chic, contemporary appearance for the home.

Bifold doors are a versatile door solution that helps to bring the outside in, creating optimum access to your garden. Opened in a concertina folding style, their ease of operation makes them a good alternative to sliding patio and French doors.

Technical Information

Slim Sight Line

When all the panels are closed, the sight line of our Sheerline aluminium folding doors is just 132mm. This affords you an uninhibited view through the glass, simultaneously allowing a great amount of natural light inside the property, leading to a brighter environment.

Thermal Performance

The profiles feature polyamide thermal breaks to enhance thermal performance and improve the U-Value. When using a centre pane that has a U-Value of 1.0 W/m²k, they can achieve an overall U-value of just 1.5W/m²K. The double rebated top and bottom tracks also provide a tight weather seal, keeping the heat in and the weather out.

Certified Weather Ratings

Each bi-fold system has been tested and passed stringent weather tests, confirming they truly keep the worst weather outside:

  • Water: Class E, 750Pa
  • Air: Class 4, 600Pa, BS EN 12207
  • Wind: Class 4, 1800Pa


Equipped with stainless steel wheels and tracks, they can be operated with ease for years to come. We also provide the choice of either a low threshold, which make it easier to transition through the doors along with rebated thresholds that offer improved weather resistance.
