Bi Fold Doors

The ultimate in luxury, aluminium external bi-fold doors sleekly combine your home with your garden. Fold the panels away on warm days or enjoy extra daylight and unbroken views when it's cooler. There's no need to worry about your heating bills or security, as they're highly energy-efficient and fitted with the best locking system available.

Our aluminium bi fold doors open concertina style to create a stunning open space and an unimpeded view of your garden. When closed, they create a wall of light and an unrivalled feeling of spaciousness.

  • Create a door system made up of between two and seven panels
  • Incorporate a ‘primary’ door that can be opened on its own
  • Built to last – made from a sturdy 70mm wide mainframe profile with welded corners
  • High performance security – each primary door has a tough Yale cylinder lock and the folding doors have top and bottom shoot bolts that hold them securely locked

We make it easy for you to create the gorgeous opening to your garden you’re looking for. One of our Anglian designers will visit you at home to give you expert advice tailored to your specific circumstances.

They’ll show you the range of styles, colours, glass options and decorative effects that you can choose to make your doors unique. Once you’ve decided what you want, they’ll measure up and give you an accurate quote.
