Overview
Aluminium Bi-Fold Windows: what you need to know
What a bi-fold window is
A window made of panels that concertina to one side, so the whole opening clears in seconds. Closed, it looks like a slim aluminium window; open, it turns a worktop into a serving hatch or breakfast bar to the outside.
Who it suits
Families who cook and eat outdoors in summer, homes with a kitchen sink or worktop facing the garden, and garden rooms or outdoor bars where you want the front to open fully.
Matched to your doors
Bi-fold windows are often paired with bi-fold or sliding doors so frames, colours and sightlines line up across the back of the house. We'll plan both together at survey.
Free survey and quote
We measure the opening, check the worktop height and advise on panel numbers at no cost. Get in touch for a quote.
The cost of waiting
What happens if you leave it
A fixed window between kitchen and patio means carrying everything round through the door.
Common mistakes we see
- Choosing too many panels, so the folded stack blocks the worktop.
- Forgetting the outside sill height when planning a serving ledge.
- Measuring before the new worktop is in.
- Picking a frame colour that doesn't match the doors beside it.

In detail
Options, materials and methods
Everything worth knowing before your survey, so you can make a confident decision.
Panel layouts
Two to four panels is typical for a kitchen window. We'll show you how far the panels stack and which way they fold so the open window sits clear of taps and appliances.
Serving ledges
Many customers line the inside worktop up with an outside ledge or bar so the open window becomes a counter. We'll check heights at survey.
Garden rooms and bars
Bi-fold windows suit garden rooms, home bars and summer houses where you want the front to open up fully in good weather.
Before your free survey
To get the most from your survey, have a think about a few things beforehand: how you use the room day to day, the look you're aiming for, any colours or finishes you already like, and whether other building or decorating work is planned. Photos of styles you like are useful too. None of this is essential, as we'll guide you through every choice, but it helps us give you a precise aluminium bi-fold windows quote in a single visit.
What our customers tell us matters
Our one Facebook recommendation so far describes the installation as done professionally, fitted neatly, with a friendly and efficient team. That's exactly what we aim for on every job: turning up when we say we will, protecting your home while we work, fitting carefully, and leaving the room clean. If you've had work done by us, we'd be grateful for a Google review.
Paying for your project
We keep payment simple and transparent. A 65% deposit is taken to order your products from the manufacturer, and the balance is due on the day of completion, once the job is finished. We don't publish prices, because every home is different. Get in touch for a quote. Your written quote will show exactly what you're paying for.
Choosing a brand
We supply and fit products from manufacturers rather than making our own, which means we can recommend what genuinely suits your home. Origin aluminium is our best seller and carries a 20-year manufacturer's guarantee. RK Steel is our main steel brand, for internal and external windows and doors. We also supply Palladio and Bel'M. At survey we'll explain the differences in plain terms.
Understanding the guarantee
Because we don't manufacture, the guarantee on your product is the manufacturer's guarantee, and it varies by brand. Origin products carry a 20-year manufacturer's guarantee. For other brands, we'll confirm the guarantee for your specific product in writing with your quote, so there are no surprises later.
Getting an accurate quote
Every opening is different, so we don't publish prices. The fastest route to a firm figure is a free survey: we measure, check the condition of the opening and talk through the finish, glazing and hardware you want. You'll get a written quote listing exactly what's included before you decide anything.
Homes we work on
Our customers are mainly households: replacements in existing homes, renovations, extensions and self-builds. P Black and Son supplies products from manufacturers and fits them, so you deal with one team from first visit to final handover.
