Discover an eye-catching array of concertina accordion doors, ideal for open plan living. These concertina doors are also often called internal folding doors or internal bifold doors and are wonderful for adding the versatility of an open plan room, whilst still providing the ability to create smaller, more friendly spaces where needed.
They’re basically an internal partition, providing a cosy setting whilst enabling light to flood naturally through your property.
Simply put, a concertina door is another way of describing a bifold door. The name takes inspiration from the musical instrument concertina or an accordion. As these instruments are folded open and closed to create music (similar to the way in which fire bellows are operated), the doors are slid open and closed using panels.
Folding doors may be called bifold doors, but the design is essentially the same, and dates as far back as Roman times.
Archeological finds in Pompeii have shown that Romans favoured wooden concertina doors; according to historian Peter Connolly, Romans “disliked single-leaf doors and wherever possible, both inside and out, they used double or even folding doors.”
Today the design remains the same, but different materials have been used throughout the centuries to update the look and feel to represent design trends of the times. Today, the majority of sliding external concertina doors are made from materials such as wood, UPVC or aluminium, and many contain window or glass panels to amplify the natural lighting.
Interior and exterior bifolds use a straightforward tracking system which runs along the panels. These are linked via a train. Because the doors fold in on themselves, they slide along the tracking system effortlessly thanks to a set of wheels or a lower tracking system – resulting in seamless motion and discreet operation.
These doors typically come in pairs, particularly internal ones, with two doors folding to one side or four that separate in the middle – as well as two doors folding back to either side. Your door comes with all fittings and tracking already fitted and can be opened either outwards or inwards, making them incredibly versatile.
The majority feature between two and seven panels, all of which can be linked with hinges and connected to the roller track at the top or bottom of the door (or both).
These doors offer homeowners a number of different advantages.
Space saving. For one, the sliding mechanism allows doors to open without having to take up space in the room, making them an ideal installation in compact living spaces. This sliding opening also makes a pleasant departure from more conventional doors that open outwards, so they’re also good for modern homes that have a contemporary aesthetic.
They can be used both inside the home and out, making them a versatile design choice. Internal concertina doors, particularly, take up very little space when they’re open, making them the ideal option for smaller rooms like kitchen pantries or laundry rooms. Why not have one that opens into your wardrobe? You’ll be able to access the whole space at once, since it opens both sides.
These particular doors fold up panel by panel, so they don’t take up much space when open, either.
Versatile. Of course, you can blend both interior and exterior design by using the folding doors as gateways to your patio, garden, orangery or conservatory. When closed, the windows in the doors allow in plenty of natural light and enable you to enjoy views of the outdoors. When open, these space-saving entryways make it easy for you to step in and out and to carry things like toys, drinks trays and other items in and out without the hassle of dealing with door handles.
Extra natural light Without a doubt, one of the real plusses of having external concertina doors is the breath-taking views they offer. They literally bring a little of the outside in (without any mess). What’s more, they let a significant amount of light in meaning you’ll save electricity bills.
