About Our Bi-folding Doors
These beautiful bi-folding doors create a room with a view room, creating extra room for entertaining guests and bringing the outside inside. Unlike standard patio doors, bi-folding/ folding doors slide open to give over a 90% clear opening and stack out the way. We are able to produce these doors in many different configurations opening in or out, so that the panels can slide and fold away to an unused part of your garden or room - such as a party wall or fence. Depending on the width of your opening our bi-folds come with between 2 and 7 panels as standard, but can be up to ten for wider openings (on request). Each door panel can be up to 1 metre in width.
If you are looking for a supply and fit service, rather than supply only then please contact us. We have a database of around 4500 trade customers and we will find up to 3 different supply and fit companies in your area.
Traffic Doors
During the winter months you often just want to pop out into the garden without having the slide and fold any panels - this is where a traffic door comes in to its own. Most of our aluminium bi-fold doors can have a traffic door, which can be a panel on its own, or attached to the other panels. For example, a 3 pane door can be either a 2-1 split, or 3 panels all folding one way, but both types have a traffic door. On a 4 pane door you must have a 3-1 split to get a traffic door.
Integrated Blinds
Another popular option when ordering our bifolding doors is to
specify our unique integrated blinds, with aluminium blades. These blinds are actually
fitted between the 2 sheets of glass in the double glazed unit.
Being inside the sealed unit they never need dusting, will not
rattle in the wind and cannot be played with or damaged by
children. Perfect for use in a Bi-folding door used as a room divider or office partition as they can make rooms and offices feel more open plan, and has both the ability to allow light and privacy. The blinds can be raised and lowered and all sizes will tilt.

Alternative to Bifolding Doors - All Sliding Panels Patio Doors
Our all-panels-slide patio doors are another option if you
decide our bi-folds are not exactly what you require. Unlike

any fixed panels - they are all free to slide.
