Unlike ordinary sliding patio doors, bi-folding doors give over a 90% clear opening. The opening creates extra room for entertaining and lets the outside in. We are able to produce these folding sliding doors in many different configurations in order to make the panels slide and fold away to an unused part of your garden or room. We can manufacture doors with between two and seven panels as standard.
Our Continental Bifolding doors fold open and slide away into a tight stack. The neat stacks can be right, left or split between right and left to an unused part of your garden or room. The ability to fold back upto ten panels for over a 90% opening is one of the biggest draws of bifolding doors.
You can have almost any glass you wish in your Bi-folding doors. They can be supplied glazed or unglazed for 28mm sealed units. Low E, Argon gas filled sealed units, 1.2 centre pane value, toughened safety glass as standard.
For example; clear toughened safety glass, self cleaning glass and solar control glass, laminated glass, anti-sun, georgian bars and integrated blinds inside the sealed units.
Heavy duty shoot bolts secure the door between each intermediate panel (each operated by a pop-out T-handle). They are specially designed to fit exactly into the outerframe, tightly securing the doors inplace. The shootbolts are top and bottom of each intermediate panel, protecting the doors against forced entry.
The pop-out T-handles on the Continental Bifolding Doors on each intermediate panel operate the shootbolts between each interlock. They are clean and simple making them very asthetically pleasing and giving the doors character and sets them apart from other bifolds.
They have a key locking facility for added security and come in a range of colours.
Our Continental Folding doors run on four wheel bogie assemblies that travel on twin stainless steel tracks, resulting in easy graceful operation.
These high strength rollers exceed the required weight factors, so that no matter what the weight of the doors you still get the same easy-side action, for which Duration's bifolds are known.
Being manufactured from aluminium means that the profiles can be made very slim, with out compromising the strength of the Bi-folding doors. This not only looks much more aesthetically pleasing, but allows you to maximise the glass area, letting in more light.
The meeting stiles are just 140mm and each leaf is just 64mm wide.
With our Continental Bifolding Doors you can choose the colours of your handles, hinges, gaskest and spacerbars, to completly colour customise your doors.
A traffic door allows quick and easy access through your Bi-folding Doors from the inside and outside, operating independently of the folding panels, much like a standard residential door.
As such it uses a standard Lever Lever handle. The highly functional design of this handle means that it is pretty much an industry standard door handle and can be found on most all residential and commercial doors.
All traffic doors come with this high security anti-bump locking cylinder as standard. This high security snap secure cylinder, is pick resistant, bump resistant and drill resistant.
It passes PAS024 testing without the need for security handles or cylinder guards. The locking cylinder provides the highest levels of security demanded by the BSI giving you added peace of mind for no additional cost.
There are three low threshold options for our Continental Folding Doors, a 22mm room divider threshold (internal use only), a 34mm thermally broken low threshold and a 34mm thermal broken ramped low threhold, which is unique to Duration Windows.
The ramped low threshold makes adhering to Part M (wheel chair access) of the building regulations easy and is perfect for keeping flush floor levels from outside to inside across decking.
