Also known as multi-fold doors, concertina doors and bifolding doors these innovative folding sliding doors have become hugely popular thanks to their ability to provide wider unobstructed openings than traditional French or sliding patio doors.
These folding sliding doors add the ‘WOW’ factor to any new home extension and are also a popular upgrade for conservatories where they really do provide the opportunity to bring the outside inside on warm summer days.
As the doors are opened the individual door panels fold and slide to neatly stack to the inside or outside on one or both sides of the aperture creating a seamless extension to your living space whether they are installed as an external or internal door. Some styles will also include a traffic door that provides single door access without having to open up the complete door which can be especially useful in the winter. Doors installed into brickwork openings can be manufactured up to 6 metres in width and in many different designs and colours. Bifold doors installed into conservatories can be supplied up to 3 metres wide providing a reinforced eaves beam has been specified for the conservatory roof.
Installing a folding door in a home extension allows natural light to flood into the room and the use of argon gas filled Low E double glazing ensures that during the colder months of the year your valuable heat is reflected back into the room to minimise your heating costs. Bifold doors are also often used to separate the main home from the conservatory allowing the two areas to merge into one extended living space when the doors are fully open.
The choice of aluminium, timber or PVCu doors offers homeowners a comprehensive choice of folding doors to suit their budget and specific requirements.
Alumium bifolding doors remain a very popular choice as they are virtually maintenance free and are manufactured from strong, durable thermally broken aluminium profiles with slim sightlines. They are available in a range of over 200 different paint finishes in a choice of matt, silk or gloss finishes and you can also choose a dual colour offering a different colour outside to inside.
Timber bifolding doors are available in hardwoods such as Meranti or European Oak and are supplied factory finished in a choice of translucent stain finishes or any RAL colour paint finish in gloss, silk or matt. The timber profiles are engineered to ensure no twisting or warping occurs and as timber is a natural insulator a timber bifolding door can achieve an exceptionally low 1.4 U-value making them the most energy efficient folding door.
The continued growth in demand for affordable folding sliding doors has led to the increased availability of PVCu bifold doors due to the substantial cost savings available.
The latest generation of PVCu bifolding doors have been specifically designed with slimmer profiles that eliminate the wide bulky sightlines previously vassociated with PVCu folding doors. Secure aluminium track systems with low thresholds and concealed hinges have also replaced the exposed gearing and high thresholds from first generation doors offering an aesthetically pleasing door with similar sightlines to those of timber or aluminium doors.
Colour options have also been increased with additional wood grain finishes such as grey, black, light green, dark green, cream and Irish oak providing an affordable folding door for everyone.
