Bifold doors, also known as sliding folding doors have traditionally been used in interior locations. In the past few years' new exterior bifolding doors have become available. They are an attractive alternative to the traditional sliding patio or French doors. This article will tell you why you should consider this versatile option.

These doors are sometimes referred to as zig-zag doors. This provides a clue to how they work. They are usually made up of 3 or more glass panels that can be joined together in a number of configurations. If an odd number of panels are used a single one can be configured as a normal swing door. They are often used in Restaurants and cafes allowing the premises to be completely open to the street when the weather is suitable.

Bifold doors have much greater flexibility than sliding patio doors or French doors. They can be fully opened, completely closed, or partially opened depending on the amount of space required. Their ability to connect the inside to the outside is unsurpassed. For example they allow the whole of the back wall of a house to open out onto the garden.

Doors are available in a range of materials including PVCU, aluminum, timber and aluminum-clad timber. The latter, although expensive, allows hardwearing aluminum on the outside and an attractive wooden finish on the inside. PVCU doors are usually the cheapest option but are limited in colors (white). Aluminum doors can be powder coated so are available in almost any color or finish. Timber doors are usually made of hardwood or laminated timber. The latter is essential if the door were in a South facing, exposed or coastal position. In that location environmental extremes would cause hardwood doors to warp and malfunction. Any reputable bi fold door manufacturer will advise you of the best choice for your situation.

When choosing bifolding patio doors it is essential that you select ones that are constructed to the latest regulations. They must be completely weather proof in even the harshest conditions. The glazing must also be optimized to give the best thermal insulation. Other considerations are the size and number of panels, how these panels can be configured, the type of door threshold and the location of trickle vents. Quality gearing is also essential if you want smooth and durable door performance.

These kinds of doors are becoming more and more widely shown in the media. They are often seen in home renovation or remodelling TV shows to provide that elusive wow factor. Their versatility in configuration and availability in various materials make Bifold doors a tempting option for anyone considering installing or upgrading a traditional patio door.
