Bi-fold patio doors can make a beautiful addition to any property, but with so many different styles and materials on the market, it’s important to choose the right bi-fold patio door for your home.

What Are Bi-Fold Doors?

Bi-fold doors are made of several panels that slide open along a track and fold up in a concertina style. Bi-fold patio doors are glazed with glass to allow light to pass through and are well-suited to both interior and exterior spaces.

Bi-fold patio doors are a unique solution to creating semi-permanent open plan living areas, or accessing more of your walk-in wardrobe.

External bi-fold patio doors are usually found at the back of a property, as a means of showcasing a garden in bloom, allowing more light into the property, and making better use of outside space during the summer. Bi-fold doors can vary in size, starting from just under two metres wide to over four.

How To Choose Bi-Folding Doors

Internal Bi-Fold Doors

Not just for patio use, bi-folding doors add value to other areas of the home too. Because bi-fold doors fold back on themselves, bi-fold patio doors are inherently space saving. This makes them perfect for connecting and dividing rooms within your property, without compromising on accessibility.

Enhancing natural light, they can create the illusion of a larger space from within a smaller room, owing to the visibility of larger rooms elsewhere. And when you don’t want these areas to be visible, bi-fold patio doors can also be fitted with blinds or curtains for added privacy.

External Bi-Fold Doors

If you choose to have bi-fold patio doors fitted as an external door, there are more benefits than first meets the eye. Open up your kitchen to a summer breeze and enjoy an alfresco dining experience, which can still be enjoyed even if the weather changes.

External bi-fold patio doors are also the perfect solution to making better use of your outside space. They can be folded back to reveal additional outside seating, which blends seamlessly in with the interior.

A wonderful addition to any summer party,  these doors allow you and your guests to make full use of both the internal living and external garden areas.

UPVC Bi-Fold Patio Doors

UPVC bi-fold patio doors require the smallest initial outlay and require little maintenance in comparison to timber framed bi-folds, as UPVC doesn’t warp or rot when exposed to the natural elements.

UPVC is available in a wide variety of colours and finishes, which means you aren’t just limited to the classic white frames.

Aluminium Bi-Fold Patio Doors

Aluminium bi-fold patio doors are more expensive in comparison to UPVC bi-fold doors, but you certainly get what you pay for.

Aluminium is an inherently strong material, which means that aluminium bi-fold patio doors often have thinner frames, but can still carry the same amount of double glazed glass as UPVC and timber bi-folds.

This gives your bi-fold doors a sleeker appearance, so aluminium bi-fold patio doors are perfect for maximising the amount of light coming into your home.

Aluminium’s strength also means that aluminium bi-fold patio doors will retain their shape much better than their UPVC or timber counterparts.

Aluminium bi-folding doors are highly durable, being able to withstand all weathers with discolouration or warping, which makes aluminium bi-folds ideal for exterior patio doors.

 

Timber Bi-Fold Patio Doors

Think bi-fold doors are only suited to modern builds? Think again. Timber framed bi-folding doors are the perfect addition to any period-style property.

They are perhaps the most desired in terms of appearance, however, they do require regular painting and sealing every few years to ensure the wood doesn’t warp out of shape.

Warping causes gaps and draughts to appear, so regular maintenance of timber bi-fold patio doors are a must to ensure the doors remain in good working order.
