Buckinghamshire: bifolding doors for extensions

Thresholds range from a raised weathered sill to a low or flush threshold for level access between floor and patio. Low thresholds rely on drainage outside, such as a slot drain, and some shelter from driving rain. The right choice depends on exposure, patio levels and how the doors are used.

Bifold door tracks need keeping clean: vacuum or brush grit from the bottom track and drainage slots regularly, wipe frames with mild soapy water and lightly lubricate the locking points. Panels that drag or catch usually need adjustment at the hinges or rollers, which a glazier can carry out.

Security on bifold doors comes from multi-point locks on the traffic door, shoot bolts top and bottom on the folding panels, internally glazed beads, anti-lift track design and hinges that cannot be removed from outside. Ask whether the system has been tested to PAS 24 and fit an anti-snap cylinder.

Bifold doors take longer to manufacture than standard doors because each set is made to the opening and coated to order. Fitting a typical set usually takes one to two days, depending on width, removal of old doors and any making good to plaster, flooring and the patio outside.

What applies in Buckinghamshire

Approved Document K requires safety glass in critical locations in England: glazing in doors and in side panels within 300 mm of a door, up to 1500 mm above floor level, and any glazing in walls or partitions up to 800 mm above floor level.

Listed buildings in England need listed building consent for most changes to historic windows or glass, and conservation areas can restrict changes visible from the street. Speak to the council's conservation officer before ordering.

Buckinghamshire is inland, around 66 km from the nearest coast at its closest point, so salt exposure is rarely a factor.

Long, heavy bifold panels need planned access through the house or a side passage, and parking close by for unloading. In terraces and flats, check permitted development rights, freeholder consent and conservation area rules before ordering.

Choosing your bifold doors

Panel configuration

From two to seven or more panels, folding left, right or splitting both ways, with or without a separate traffic door.

Integrated blinds

Blinds sealed between the panes of each unit, controlled by a magnetic slider, so they never need dusting or catch on folding.

Glass specification

Toughened low-E double glazing as standard, with triple glazing, laminated security glass or solar-control coatings available.

uPVC bifolds

A lower-cost option with bulkier frames, suited to smaller openings with fewer panels, available in white, grey and woodgrain foils.

Bifold Doors in Buckinghamshire: questions

Should bifold doors open inwards or outwards?

Outward-opening bifold doors are more common because the stacked panels sit outside and leave the room clear. Inward opening suits balconies, raised decks or tight patios where outward panels would block the space. The direction also affects weather performance and furniture layout, so it is decided at survey with the room plan in mind.

Bifold or sliding doors: which should I choose?

Bifold doors suit you if you want almost the whole opening clear in summer, because the panels fold and stack to the side. Sliding doors suit you if you want the fewest frames and the widest view when closed, because large panels glide past each other. Many people decide by how often they will fully open the doors.

What guarantee comes with bifold doors?

Manufacturer guarantees apply to the frames, coating, hardware, rollers and sealed units, and the terms are confirmed in writing. Cover for running gear can depend on regular cleaning and adjustment, so read the conditions. Guarantee terms for the installation are set out in writing with your quote, so you know what is covered before going ahead.

Can bifold doors have a level threshold?

Yes, most bifold systems offer a low or flush threshold for near level access between inside and out. It works well with a drainage channel outside and some shelter from wind-driven rain, because a flush track is less weather resistant than a raised sill. The glazier checks the patio and floor levels and exposure at survey.
