Cannock: bifolding doors for extensions
In England, replacement doors with more than 60% of the internal face glazed should achieve a U-value of 1.4 W/m²K or a Doorset Energy Rating of band C under Approved Document L. New openings in extensions are assessed with the whole extension, and large glazed areas may need energy calculations.
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.
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.
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.

About Cannock for this job
- Postcodes covered
- WS11, WS12 and the surrounding area, including Burntwood, Bloxwich and Rugeley
- Coast
- Cannock is well inland, around 86 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In Cannock the midwinter sun reaches about 14° above the horizon at noon, with roughly 7.4 hours of daylight, rising to about 61° and 16.6 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.

Bifold Doors in Cannock: questions
Do bifold doors leak or let in draughts?
Well-made bifold doors fitted level and square should keep out wind and rain, but they rely on accurate installation, a sound lintel and working drainage. Leaks usually come from blocked track drainage, a flush threshold on an exposed elevation or panels that have dropped out of adjustment. Keeping the tracks clean prevents most problems.
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.
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.
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.
