Modern Aluminium Bifold Doors

There are few more modern home innovations than bifold doors. They can make a significant difference to any home here in the Newbury and Berkshire areas. Operating on an inline track much like patio doors, the bifold variant instead works with collapsing eaves that neatly fold at one side of the framework. Sometimes called ‘concertina doors’, they were initially used in restaurants and cafes.

With this unique design, bifold doors arguably deliver enhanced visual appeal compared with alternative back doors. Coupled with the fact that slimline aluminium is used, and our bifold doors deliver sleek, eye-catching aesthetics wherever they’re installed. Better yet, customisation options allow these Smart systems to effortlessly suit both modern and traditional properties.

Through our industry leading supply chains, we can offer aluminium bifold doors with a dual colour option. With this, you can choose a different shade internally to externally. Smart provide a range of textured finishes and fade proof foils to ensure you’re getting the excellent visual appeal for the years to come. We have something for every budget and every style of home.

Bi-fold doors can be installed to serve a variety of purposes. With one of our bespoke orangeries, a wide set of bifolds can be installed a means of entering the garden. Meanwhile, you can also have them retrofitted to your house’s original architecture, allowing plenty of natural light to flow into the home. They can even be installed an internal divider within a larger room.

Thermally Efficient

Our aluminium bifold doors offer the complete thermal performance. Keeping your doors open during summer will provide ample ventilation for the home or extension, while thermal measures ensure maximum heat retention during the colder months.

The aluminium profile we use has been thermally broken, adding internal chambers. These work to prevent the ingress of cold air. All our bifold doors are fitted with thermally retentive double glazing as standard, and we offer triple glazing as an upgrade.

Durable & Long Lasting

Aluminium bifold doors are famed for their excellent lifespan. The entire system is made from the most durable and high quality materials available. The track will never become sticky or harder to operate while the framework will never bow, distort or warp.

Despite requiring very little maintenance, you can expect up to 25 years of use from your bi-fold doors if correctly looked after. Over the duration of this time, the doors will remain fully watertight in even the most extreme weather conditions.

Comprehensive Home Security

You get home security assured with a set of bifold doors. Aluminium is a naturally more robust material than uPVC or timber. Meanwhile, our thick double or triple glazing will prove incredibly difficult for an unwanted intruder to damage or break.

Meanwhile, the Visofold 1000 system is fitted with multipoint locking systems as standard. These are supported by shootbolt locking and lift-up handles, both of which enhance the standard of home security these doors offer. You can have complete peace of mind.
