If you’re considering home improvements, you’ve likely asked yourself: Are bifold doors a good idea? It’s a question many homeowners and trade installers grapple with when planning renovations. Bifold doors have become increasingly popular over the past decade, transforming how people connect indoor and outdoor spaces. But before you invest in new bifold door systems, it’s worth understanding what makes them valuable and whether they’re the right choice for your property.
Understanding What Bifold Doors Actually Are
Before looking into benefits, let’s clarify what we’re discussing. Bifold doors (also known as bi-fold doors or folding doors) are door systems comprising multiple panels that fold back on themselves when opened. Unlike traditional French doors or sliding patio doors, bifold door configurations allow you to open up an entire wall space, creating a seamless transition between indoor and outdoor areas.
The typical bifold door setup includes:
- Multiple glass panels (usually between 3-8 panels depending on your opening width)
- Sturdy aluminium frames that support the weight and movement
- Top and bottom tracks that guide smooth operation
- Pivot hinges enabling the folding mechanism
- Weatherproofing seals protecting against draughts and water ingress
At Great Harwood Windows, we install aluminium bifold doors using premium Smart, SAS, and Smoothfold systems. By using only the best profiles, we can ensure that all our bifold doors are of the highest possible standard.
Why Consider Bifold Doors?

Bifold door benefits extend far beyond simple aesthetics. These systems fundamentally change how you experience your home by:
- Creating flexible space that adapts to your lifestyle
- Maximising natural light penetration
- Enhancing property perception and marketability
- Offering superior performance compared to traditional door types
- Providing contemporary design that appeals to modern homebuyers
How Bifold Doors Transform Your Lighting
One of the most immediately noticeable benefits of bifold doors is the dramatic increase in natural light entering your home. Unlike traditional doors that block views and light with their solid frames, bifold door panels feature extremely slim sightlines.
When fully opened, they create an expansive opening that floods your interior with daylight. This isn’t merely an aesthetic advantage; it’s a genuine functional benefit.
Benefits of increased natural lighting include:
- Improved mood and wellbeing: studies consistently show that natural light enhances mental health and circadian rhythms
- Reduced reliance on artificial lighting: lowering your energy consumption throughout daylight hours
- Enhanced perception of space: rooms feel larger and more connected with better light distribution
- More appealing living environments: spaces feel warmer and more inviting
The Visual Connection Between Spaces
When you fully open your bifold door installation, you’re creating a visual connection between your indoor and outdoor areas. This continuous sightline makes smaller gardens appear more integrated with your home, and larger outdoor spaces feel like natural extensions of your living area.
Trade installers frequently report that clients are surprised by how dramatically bifold doors enhance the perceived size of rooms. This perceived expansion translates into genuine lifestyle improvements, as families gain flexible, multi-functional spaces.
Security Features: Are Bifold Doors Actually Secure?

A common concern about bifold doors is security. After all, with multiple glass panels and a folding mechanism, aren’t bifold doors more vulnerable than traditional doors? Let’s examine this carefully.
Modern Security Technology in Bifold Door Systems
Quality bifold door installations from reputable manufacturers incorporate sophisticated security features including:
Multi-Point Locking Systems Rather than a single lock at one point, modern bifold doors feature multiple locking points along the frame. When fully closed, these locks engage simultaneously across the entire door width, distributing security across the whole structure. This is far more secure than traditional single point locks.
Toughened Safety Glass Bifold door glass is invariably toughened (tempered) safety glass, specifically designed to resist impact. Unlike ordinary glass, toughened glass doesn’t shatter into dangerous shards, it fragments into small, relatively harmless pieces. This glass specification meets stringent safety standards and significantly resists forced entry attempts.
Laminated Glass Options For enhanced security in vulnerable locations, laminated glass adds an additional security layer. Laminated glass consists of two glass panes bonded with a resilient plastic interlayer, making it extremely difficult to penetrate. Burglars typically avoid properties with laminated glass due to the time and noise required to breach it.
Reinforced Frame Construction Modern bifold door frames employ robust aluminium construction with internal reinforcement. These aren’t flimsy structures, they’re engineered to withstand considerable force. The folding mechanism itself distributes force across multiple panels rather than concentrating it at a single point.
Secure Pivot Hinges The pivot hinge system on quality bifold doors is engineered for security. Professional installations ensure hinges are correctly fitted and regularly maintained, preventing potential weaknesses in the folding mechanism.
As you can see, bifold doors are definitely worth it and are an excellent investment in any property. To find out more about our bifold doors or any of our products or services call 01254 690 009 or e-mail info@greatharwoodwindows.co.uk.
