Who orders trade aluminium bifold doors?
Mostly builders and main contractors, conservatory and extension specialists, window and door installers and housing developers. Typical uses include kitchen and living extensions; garden rooms and orangeries; restaurant and café frontages.
Bifold doors are specified by overall width, number of panels and how they fold. Your quote shows the configuration so you can check it against the opening before production.
A traffic door is a single panel that opens like a normal door, so the set does not have to be folded back just to step outside.
The opening above a bifold carries the weight, so the lintel must be level and stiff enough. Check this with the builder before the doors arrive.
Flush thresholds give a level transition inside to outside but need a drainage detail outside. Tell us if you need one so the right threshold is supplied.
How should you measure?
The structural opening above a bifold carries the running gear, so confirm the lintel or steel is level and can take the load before you give us final sizes.
Which building regulations apply?
Replacement external doors in England should meet a U-value of 1.4 W/m²K under Approved Document L. Glass in doors and side panels below 1500mm is a critical location under Approved Document K, so it must break safely (toughened or laminated to BS EN 12600), be robust or in small panes, or be permanently protected. Doors into new homes also need to meet Approved Document Q for security, which is usually shown with PAS 24. Replacing a door that is more than half glazed is notifiable building work, self-certified through a competent person scheme or approved by building control.
Wales
In Wales, replacement external doors must meet Approved Document L (Wales), and glass in doors and side panels in critical locations must meet the safety glazing guidance in Approved Document N, usually with toughened or laminated safety glass. Replacing a door that is more than half glazed is notifiable building work, self-certified through a competent person scheme or approved by building control.
Scotland
In Scotland, replacement doors in a house do not normally need a building warrant, but they must still meet the building standards in the Technical Handbooks, including energy and safety glazing. Check with the local authority for flats, listed buildings and conservation areas.
Northern Ireland
In Northern Ireland, replacement doors should meet the energy guidance in Technical Booklet F1, and glass in doors and side panels the glazing safety guidance in Booklet V. Check with your council's building control service before work starts.

Questions trade customers ask
How many panels should a bifold door have?
That depends on the width and how you want the panels to stack. As a rough guide, each panel is up to about a metre wide; we will suggest a layout when you send the opening size.
Do bifolds fold inward or outward?
Either. Outward folding is more common because it keeps the panels out of the room.
What is a traffic door?
A single panel that opens like a normal door for everyday use, without folding the whole set.
Can you match the colour to aluminium windows?
Yes. Order them together in the same RAL colour.
