Bifolding doors for extensions for homes and businesses in Slough
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 door panels have wider frames where they meet than a sliding door, because each panel needs its own frame and hinges. A five-panel set shows four vertical sightlines when closed. If the view matters more than a fully open wall, a sliding door may suit better, so compare both.
Creating a new bifold opening in an external wall is structural work that needs building regulations approval and a correctly sized lintel or steel beam. Replacing existing doors in the same opening is simpler. Planning permission may also be needed for new openings in listed buildings, flats or conservation areas.
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.

- Coast
- Slough is well inland, around 67 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In Slough 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
- 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.
- 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.

Approved Document Q applies to new homes in England, where doors and windows are expected to meet PAS 24 or an equivalent standard. It does not apply to replacements in existing homes, but PAS 24 products are still a sensible choice.
Specification choices
Low or flush threshold
A low-profile track for near level access between inside and out, paired with drainage outside and some shelter.
uPVC bifolds
A lower-cost option with bulkier frames, suited to smaller openings with fewer panels, available in white, grey and woodgrain foils.
Integrated blinds
Blinds sealed between the panes of each unit, controlled by a magnetic slider, so they never need dusting or catch on folding.
Bifold Doors in Slough: questions
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.
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.
How much do bifold doors cost?
The cost of bifold doors depends on the opening width and height, number of panels, material, colour, glass, threshold type and the condition of the opening. Aluminium usually costs more than uPVC, and wider sets, triple glazing and special finishes add more. See the guide prices for typical ranges; the written quote fixes the price for your specification.
