Bi-Fold Doors

Bi-folding doors can transform an ordinary room into a spectacular and versatile space that becomes a real feature of your home. Available in a selection of colours and crafted in Aluminium, you can also choose from various leaves, opening to left or right, in or out, as you wish. In each case, everything is carefully made to measure, and comes complete with advanced security and safety features.


Glass specification is key when affecting the doors’ thermal performance as glass generally accounts for 80% of the surface area of the doors. Each door set carries 28mm double glazed units incorporating soft coat toughened safety glass as standard. A 28mm double glazed unit is incorporated in our range of Aluminium Sliding Patio Doors.

Sliding Facility

The bi-folding doors glide on stainless steel rollers, which allows for unrestricted thoroughfares and maximum use of space and light. The smooth contours and curved clean lines create an attractive aesthetic that will compliment any home, whatever your taste or style.

Energy Efficient

Our doors include multiple rigid rubber seals and draught excluders to ensure that you get nothing but sunlight passing through your doors. Our bi-folding door system utilises the latest polyamide thermal barrier technology. This advanced profile technology creates a thermal transmittance barrier between the cold outside and the warm inside.
