Substitute windows and doors used to only be available in grey aluminium if you didnt want wood and the styles rarely bettered the aesthetics of the buildings they adorned. The result of this are many aesthetically spoiled period homes with windows which are now a fire hazard because they openings are too narrow to escape through.

Then they became available in white PVC which were firstly cheap and of low quality and poor design but which went on to become the excellent quality they are today and designed to suit the house not the pocket.

House owners now have a much better selection of door and window materials and styles to select from.

For numerous years, there has been a really big market for patio doors, which provide convenience and provide light and air into a home whilst offering a highly effective thermal barrier when shut. The acme of the patio door marketplace are Bifold patio doors which offers good versatility and great aesthetics. Anyone thinking of buying patio doors now should first consider whether they should increase their investment to a bifolding door.

Bifold doors can be arranged to span a very wide aperture or smaller spaces, behaving when closed as a glass wall to let in increased light and to allow sweeping views over the outside vista or garden. They can very easily open up an entire wall to allow seamless integration of external and internal areas, e.g., for parties or for kids to play safely inside and outside on a lovely day. They are also perfect for maximizing space in restricted situations such as an opening onto a balcony in a small flat.

Fully opened, the doors concertina and store compactly to left, right or both sides to limit their intrusion. They can be arranged to provide french style doors when full opening is not required and a single opening door for pedestrian access in the normal way.

Available in many modern materials, including timber, aluminium, PVCu and aluminium clad timber, this product is available in a wide range of colours and finishes from specialist window companies. Although expensive, aluminium clad timber, gives you the quality finish inside and the selection of colours and low maintenance options provided by aluminium cladding.
