Unifold Bi-folding doors.

Aluminium Bi-Fold Doors Provide Superb Ventilation.

Because our ultra slim bi-fold doors retract to almost threshold length, they create a wide aperture that’s perfect for inducting fresh air into your chosen space. During warmer weather, your bi-fold doors can be fully opened to create an unbroken connection with the outside – keeping you and any visitors to your London home cool.

The improved ventilation provided by your new aluminium bi-fold doors will stop condensation from forming. This means you won’t need to worry about the build-up of mould, which, if left untreated, would be time-consuming and expensive to treat. Your bi-fold doors will be an investment that protects your London home 24/7.

Our Aluminium Bi-Fold Doors are Perfect for Homes and Businesses.

Although aluminium bi-fold doors are often used in residential settings, their versatile design means they’re often used for commercial projects too. If you own a business in London and need a stylish door design that’ll add an all-important finishing touch to your project, our beautiful internal frameless bi-fold doors will suit your requirements in full.

The absence of frames in our internal aluminium bi-fold doors results in clean, minimalist designs that look stylish. They are ideally suited for meeting rooms, providing both privacy and visibility in equal measure. The expansive glazed areas that characterise your bi-fold doors will also transfer light into adjoining rooms to create a more connected space.

Add Style and Save Money with Ultra Slim Bi-Fold Doors.

Finepoint Glass designs and manufactures aluminium bi-fold doors that are optimised for thermal efficiency. Although incredibly stylish, our bi-folds deliver superb levels of performance that’ll keep your London home warm.

The profile in your new aluminium bi-fold doors will contain a polyamide thermal break and be fitted with glazing that’s between 24-44mm thick. These features will work together to prevent heat escaping from your room.

Strong performance is evidenced by the U-values produced by our slimline bi-fold doors, which produce a minimum score of 1.4 W/m²K. Your energy bills will reduce once we’ve installed your new products, as will your carbon footprint.

Industry-Leading Security for Your London Home or Business.

Although our aluminium bi-fold doors open wide to create a superb access point, they won’t make it easy for intruders to gain entry. Security is one of our primary considerations when designing ultra slim bi-fold doors for our London customers.

To protect your home or business premises, we make sure that our bi-fold doors meet PAS 24 and Secured by Design specifications. This means your product will robustly resist most attempts to gain unauthorised access to your property or premises.

Enjoy Fluid Threshold Access with Aluminium Bi-Fold Doors

The simple and convenient operation of aluminium bi-fold doors makes them an enduringly popular choice for our customers in London. The flexible design of this style of door enables them to collapse into panels that stack neatly to the side of the building in question – creating an almost threshold-wide access point that will allow people to come and go as they please.

Our ultra slim bi-fold doors will come into their own when your household is busy. During busier times – when you’re entertaining, perhaps – visitors will be able to pass back and forth across the threshold of your London home without having to take turns. At all other times, they’ll be able to enjoy panoramic views of your garden and refreshing night breezes.

Our Bi-Fold Doors Will Fill Your London Home with Light

Aluminium is an intrinsically flexible material that can be used to create fine, minimalistic designs. Our aluminium bi-fold doors conform to a low frame-to-glass ratio that’s optimised for light entry. The expansive glazed areas in your new doors will invite in plenty of sunlight, which will create a sense of space and join your interior spaces seamlessly.

Our slimline bi-fold doors are, therefore, a perfect design choice if you want to breathe life into a room that feels dark and has become a rarely-used space as a result. Convert a lightless conservatory, extension or living area into a functional area and make your home more appealing to prospective buyers, should you wish to sell your London home later.
