Wallington: bifolding doors for extensions
The number of panels sets how the doors open. Odd numbers, such as three or five panels, usually include a traffic door that opens on its own for everyday use. Even numbers can split to both sides. Panels can fold inwards or outwards, and outward folding keeps the room clear.
Aluminium is the usual material for bifold doors because its strength allows slim, stiff panels that hold heavy double or triple glazed units without distorting. uPVC bifolds cost less but have bulkier frames and suit smaller openings. Engineered timber bifolds offer a natural finish but need periodic re-coating.
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.
Bifold doors run on rollers along a track, either top-hung with the weight carried by the head or bottom-rolling with the weight on the threshold. Top-hung systems depend on a strong, stiff lintel or steel above, so the glazier checks support before ordering, because sagging heads cause doors to bind.

About Wallington for this job
- Postcodes covered
- SM6, SM5, SM1 and the surrounding area, including Carshalton, Sutton and South Croydon
- Coast
- Wallington is well inland, around 37 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In Wallington the midwinter sun reaches about 15° above the horizon at noon, with roughly 7.6 hours of daylight, rising to about 62° and 16.4 hours in midsummer. A wide bifold opening on a south or west-facing wall brings in strong sun and can overheat a room, so solar-control glass or integral blinds may help. North-facing bifolds benefit from high light-transmission low-E glass to make the most of winter daylight.
- Access and setting
- Rural gardens often slope or sit lower than the floor, so threshold height and drainage need careful planning. Exposed open sites benefit from stiffer aluminium systems, raised thresholds and outward-opening doors that seal against the wind.
- Rules in England
- 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.

Bifold Doors in Wallington: questions
Are bifold doors secure?
Good bifold doors are secure when the traffic door has a multi-point lock and anti-snap cylinder, the other panels have shoot bolts top and bottom, the glass is internally beaded and the hinges and track resist lifting. Ask whether the system has been tested to PAS 24, and consider laminated glass for ground-floor doors.
Do bifold doors need building regulations approval?
Yes. Fully glazed replacement doors like these are controlled fittings, and in England an installer registered with a competent person scheme can self-certify them, or building control approves the work. A new or widened opening is structural work and needs building control approval for the lintel or steel. Wales, Scotland and Northern Ireland set their own requirements.
How long does it take to fit bifold doors?
Fitting a typical set of bifold doors takes one to two days on site, depending on width, removal of old doors and making good around the opening. The doors are manufactured to the survey sizes first, and the lead time depends on the system and colour; it is confirmed in writing when you accept the quote.
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.
