Bespoke Bi Folding External doors and Internal Bi folding door screens

Over a number of years the popularity of external Bi Folding doors has grown with the appeal of bringing the outside in to your home, something that has been popularised in warmer climates.

Here in the UK not wanting to be left behind we have embraced the concept and all types of bi folding doors are available in various materials and designs.

Bifold doors are also known as bifolding doorsfolding sliding doors, glass sliding doors and sliding room dividers. In its simplest term, a bifold is a door that slides open while its panels fold up and stack neatly against the wall – like a concertina.

Internal bi folding doors are manufactured mainly in Poplar but can be manufactured in any species required. Unlike external joinery internal work is not subject to the rigors of the English climate and is therefore not restricted to specific species of timber.

External bi folding doors and frames are manufactured using traditional joinery methods and the bi folding mechanism and locking system is high quality.

In addition all external bi folding doors fully comply with today’s building control requirements.  Locking systems, glazing and the construction of the product must all comply with current legislation.

To reach these standards all locking systems comply with the recent Part Q of the building regulations and all glazing is in the form of double glazed units argon filled, UV film coated and toughened on both sides.

Bi folding doors can open in or out and can finish flush with the internal floor level for a seamless transition from inside to out.

Internal bi folding door screens are an ideal solution when closing an open space or through lounge / kitchen diner, but maintaining the flexibility of the larger space when needed for parties, family dinners etc.

The process of manufacturing bi folding doors involves many separate operations culminating in the end product which when looked at in its finished state hides all the highly skilled and time consuming work it has taken to make.
