Craigavon: folding patio doors
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.
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.
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.
What's included
- Toughened or laminated safety glass to every panel

- BT64, BT65, BT66 and the surrounding area, including Lurgan, Portadown and Banbridge
- Coast
- Craigavon is well inland, around 34 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In Craigavon the midwinter sun reaches about 12° above the horizon at noon, with roughly 7.0 hours of daylight, rising to about 59° and 17.0 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 Northern Ireland
- Technical Booklet V covers safety glazing in Northern Ireland, including glass in and around doors and low-level glazing where people could walk into it.

Bifold Doors in Craigavon: 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.
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.
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.
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.
