Folding Doors: How much are they?
Folding doors typically start from around £1,400–£1,800 for a basic 2-panel aluminium set, but the final price depends on size, configuration, glass, and finish choices.
Let’s be honest — folding doors are everywhere. Home improvement shows love them, Pinterest is filled with them, and every second kitchen-diner seems to be opening out onto a garden through one. But are folding doors actually worth the hype? Or is it just another trend with a big price tag?
Let’s break it down — no fluff, just honest, expert advice to help you decide.

- What exactly is a folding door?
- The lifestyle benefits (spoiler: they’re impressive)

What is a Folding Door, Really?
A folding door, more commonly known as a bifold door, is made up of multiple glazed panels that fold neatly back against each other, opening up a full wall of your home. When closed, they look like large windows. When open, they blur the line between indoors and out.
They’re available in a wide range of configurations, sizes, and styles — from ultra-slim, contemporary frames to internal folding doors with industrial-style charm.
Are Folding Doors Expensive — and What Are You Actually Paying For?
Let’s be honest — folding doors aren’t the cheapest option on the market. But they’re also not just doors. When you invest in a high-quality aluminium folding door, you’re getting more than a way to open up a wall — you’re transforming the way you use your home.
The cost can vary depending on factors like the number of panels, size, glass specification, colour choice, and whether you go supply-only or include installation. But what you’re really paying for is:
- Exceptional engineering (smooth, effortless glide every time)
- Thermal efficiency that keeps your home warm and your bills lower
- Enhanced security features (think multi-point locks and PAS24 compliance)
- Longevity — aluminium frames last for decades with minimal maintenance
- And of course, visual impact that adds serious wow-factor and kerb appeal
Think of it this way — it’s an investment in lifestyle, comfort, and value. And with ranges like Korniche and Smart Visofold, you’re getting top-tier performance without overpaying.

The Lifestyle Factor: Space, Light & Living
Let’s start with the obvious — folding doors look stunning. But this isn’t just about appearances.
Here’s what they do for your lifestyle:
1. Open-Plan Living Made Easy
Want to connect your kitchen to your garden? Folding doors make the transition seamless. Perfect for entertaining, family BBQs, or just a Sunday morning coffee with the doors wide open.
2. Floods of Natural Light
Large glazed panels act like picture windows when closed — meaning more daylight and a bigger-feeling room, all year round.
3. All-Season Enjoyment
Add a roof lantern above and you’ve created a glass-box space that feels connected to the outdoors, even in winter. Fold the doors back in summer and you’ve got indoor-outdoor flow.
The Practical Benefits (That Don’t Always Get the Hype)
Sure, folding doors look great — but here’s why they’re also smart:
✅ Thermally Efficient
Modern aluminium folding doors like those from Korniche and Smart Visofold come with:
- Low U-values (from 1.2 W/m²K)
- Argon-filled double glazing
- Polyamide thermal breaks
All of which means less heat escaping = lower energy bills.
✅ Secure by Design
We get it — big glass doors raise security concerns. But not with PAS24-certified systems like Korniche, which include:
- Multi-point locking
- 3-star Yale barrels
- Shootbolts and anti-lift features
✅ Low Maintenance
Unlike timber, powder-coated aluminium won’t rust, warp, or need repainting. A quick wipe-down is all you need.
✅ Future-Proof Appeal
Adding folding doors to your home increases its visual appeal and can add value — buyers love the open-plan, garden-connected lifestyle.
“But Aren’t Folding Doors Expensive?”
They can be. But so is anything high-spec that adds genuine lifestyle value to your home.
Here’s what affects the price:
- Number of panels
- Opening configuration
- Colour & finish
- Glass type (laminated, solar control etc.)
- Threshold options (flush, rebated)

What About Internal Folding Doors?
Great question. Internal folding doors are on the rise — especially for zoning open-plan spaces post-pandemic, when work-from-home became the norm.
Why choose internal folding doors?
- Divide a lounge from a conservatory
- Create a home office that still feels open
- Add character with industrial-style frames (Smart Heritage is ideal)
They keep spaces bright, maintain sightlines, and still provide that folding-door flexibility.
So, Are Folding Doors Worth It?
Let’s weigh it up:
| Benefit | Worth the Hype? |
| Style & Visual Impact | ✅ Absolutely |
| Everyday Convenience | ✅ Especially with traffic doors |
| Energy Efficiency | ✅ With modern spec |
| Security | ✅Especially if upgraded to PAS24 |
| Price | 💸 More than French doors — but more value |
| Versatility | ✅ External or internal use |
Verdict: Yes — if you go for quality and choose the right door for your space. The hype is justified. Folding doors are more than just a trend — they’re a long-term investment in how you use your home.
