Bifolding doors for extensions in Poole
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.
The price of bifold doors depends on overall width and height, the number of panels, material and profile system, colour, glass specification, threshold type and the condition of the opening. Wide or very tall sets and triple glazing add cost. See the guide prices for typical ranges; the written quote fixes your figure.
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.
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.
What a typical job includes
- Fitting, levelling, adjusting and sealing the frame
- Written guarantee terms and advice on building regulations sign-off
- Survey of the opening, support above and floor levels
- Removal and disposal of any existing doors

About Poole for this job
- Postcodes covered
- BH15, BH14, BH17 and the surrounding area, including Bournemouth, Ferndown and Christchurch
- Coast
- Poole is about 1 km from the coast or a tidal estuary, so salt air and wind-driven rain are worth planning for. Salt deposits gather in bifold tracks and on rollers, so coastal sets need more frequent cleaning, stainless or protected running gear, and a coating suited to marine exposure. Wind-driven rain makes a raised threshold or good drainage especially important on exposed elevations.
- Daylight and sun
- In Poole the midwinter sun reaches about 16° above the horizon at noon, with roughly 7.7 hours of daylight, rising to about 63° and 16.3 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.

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.
What you can choose
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 Poole: 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.
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.
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.
