Aluminium Bi-Fold Doors

Aluminium bi-folding doors add a new dimension to any room, sliding smoothly aside to allow the outdoors in. Whether you are looking to extend a dining area onto a patio, or keep a conservatory cool in summer, bi-fold doors are a beautiful addition to any home.

You can choose to have one or two doors swinging open like traditional French doors, then slide the set to one side or the other. A two-pane arrangement can even help you to maximise the space between a conservatory and the house, by sliding unobtrusively to one side, giving a full clear opening. The choice is flexible to meet every individual requirement.

Depending on the size of space you have available you can choose between a two door option all the way up to seven doors that open in a variety of configurations. To find out what size bi-fold doors would suit your home and available space see our configuration guide below.
