Bi-Fold doors are a desirable feature which add value to your property.
Ever wished you could peel back a whole wall of your house or flat, let in the view and natural light and step directly onto the garden or balcony? That’s exactly what you can achieve by installing a Bi-fold door.
Bi-fold doors (sometimes called folding or concertina doors) are made up of multiple glazed panels that fold and stack neatly to one or both sides of an opening. They run on a track system and can be configured to open inwards or outwards, depending on your space and preferences.
When fully open, bi-fold doors create a wide, unobstructed opening that connects indoor and outdoor areas seamlessly.
At JF Doors & Windows, we supply and install high-quality bi-fold doors for homes across Trowbridge and the surrounding area.
We also supply bi-fold doors without fitting for builders, developers and trade customers who want reliable products at competitive prices.
Whether you’re opening up your kitchen-diner to the garden or sourcing doors for a rear-extension project, we’ll help you choose the right solution.
Our expert Bi-fold door supply and fit service covers everything.
Replacing existing doors or windows with bi-fold doors is generally considered permitted development, meaning no formal planning application or permission is required (unless you are in a conservation area).
From a building regulations perspective, any new glazing must comply with Part L (energy efficiency) and Part K (safety glazing). All glazed units supplied and installed by JF Doors & Windows meet the required standards as a matter of course.
Installing bi-fold doors is a skilled job that requires precision at every stage. The structural opening must be correctly formed, with an appropriately sized lintel or steel beam carrying the load of the wall above — particularly important when replacing a solid wall section or enlarging an existing opening.
The frame is then fitted plumb and square into the opening, the tracking is secured to the head and the threshold, and the panels are hung and adjusted until the whole system operates smoothly.
Threshold detail deserves particular attention. A low-profile threshold is typically used to minimise the trip hazard between inside and outside, though it’s important that the chosen threshold suits the floor levels on both sides and provides adequate weather resistance — especially in a county like Wiltshire, where a garden-facing elevation can be exposed to wind-driven rain.

Choosing the right configuration & frame for your Bi-Fold panels.
We’ll help you get the specifications right for your bi-fold doors, determining things like:
Bi-fold doors are available in configurations from two panels up to seven or more for wider openings. The panels can be arranged to all fold entirely to one side, or to split and fold to both.
The three main options are aluminium, uPVC and timber. Powder-coated aluminium is the favourite choice, allowing for slender, elegant frames that maximise the glass area for a clean, contemporary look. We recommend aluminium as the material of choice for this type of door.
Standard specification is double glazing, but triple glazing is also available for those seeking the best possible thermal performance or noise reduction. Glass coatings such as solar control glass are worth considering on south-facing elevations to prevent the interior from overheating in summer.
Additionally, blinds between the glass are a perfect pairing for bi-folding doors, keeping that clean look, reducing the need for regular blinds that get in the way when the doors are open and collect dust as well as being effected by the wind. Speak to us about this pairing when we are designing your new door.
Bi-fold door sets can be configured to fold inward or outward. Many homeowners also specify a traffic door – a single panel within the set that opens independently on a conventional hinge, meaning you can nip in and out to the garden without folding the whole set back every time.
