Replacement bifold doors in Armagh: what to know
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.
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 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.
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.
Included as standard
- Removal and disposal of any existing doors

About Armagh for this job
- Postcodes covered
- BT61 and the surrounding area, including Portadown, Dungannon and Craigavon
- Coast
- Armagh is well inland, around 38 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In Armagh 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 Armagh: questions
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.
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 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.
