Aluminium bi-fold doors with unique slim frames

Aluminium bifold doors have slim sightlines, which means they let in a vast amount of natural light. The modern ‘material of the moment’, bifold doors are becoming increasingly popular in Devon, especially for coastal properties that have a scenic sea view. They add a touch of luxury to any property and due to the fact they can reveal up to 90% of their width, they are perfect for those who enjoy entertaining or for those who want to seamlessly merge their indoor space with their garden.

Though, are aluminium doors practical for the winter? The good news is, they are! A traffic door can be incorporated into the design, to make them just as functional in the colder months of the year. A traffic door has a traditional door mechanism but can also operate as a bi-folding door, which will be handy when only wanting to quickly pop out to the garden!

Our aluminium bifold doors incorporate large panes of energy-efficient glass and are fitted with thermal barriers, that dramatically reduce heat transfer. As a result, our aluminium bifold doors will retain the heat in your home, ensuring it always is cosy in the winter, however, will keep your home cool in the summer!  Another huge benefit of aluminium, especially for coastal properties of Salcombe, Torbay & Ilfracombe, is that it is resistant to varying levels of humidity, salt spray & heat!

With a range of configurations, colours & hardware available, you can completely customise your bifold door to fit your space and style. You can have up to 7 panes of glass and have the choice of any RAL Colour. You can have a dual colour combination, with one colour on the inside and another one on the outside, and you have the option of a matt or gloss finish. We also offer a coated premium finish, which is a low maintenance scratch-resistant, metallic finish.

We are proud to offer a wide range of competitive door prices alongside a plethora of bifold door configurations & threshold options, that cleverly combine minimal sightlines, low U-values & extravagant external stylings.

Key features

Energy efficiency

Thanks to polyamide thermal break technology from Raum & U-values ranging from 1.7 W/m2K to 1.0 W/m2K, whichever bifold system you choose you’ll have the utmost confidence that they’ll conserve energy effectively, resist the weather whilst reducing your family’s energy bills in the long-run.

Safe & secure

With PAS24 & Secured by Design compliance as standard, Exeter, Taunton & Torquay homeowners & businesses both have essential peace of mind that their bifold systems will keep them safe from the very real risk of burglary. Modern bifold doors can be enhanced further by utilising an optional laminate glass upgrade within their design. You can also choose between the option of a monorail, duorail, or 3 & 4 rail option; ideal for very large apertures.

Decorative options

Able to blend with existing aluminium windows & doors, our aluminium bifold doors can be customised further with a full range of standard & bespoke colours offered within the Raum collection, this includes dual colour options to enhance interiors as well as exteriors. Even bifold handles & other accessories can be personalised too!

Threshold options

Our aluminium bi-fold doors are offered in 4 threshold options. We provide flush thresholds, low thresholds, double weather seals, and high-performance variations. Thresholds are located on the bottom track and top sill to provide weather resistance, and stop any outdoor elements from entering your home. The 4 threshold options vary by size, meaning they offer slightly different performances regarding their air-tightness, wind-resistance, and water-resistance. However, they're all rigorously tested to ensure that home security and weather resistance performances comply with strict building regulations.

A service you can rely on

"Brilliant local company. Installed a new door for my father (after a recommendation by a friend). Great product, great price, but (& I can not stress this enough) their kindness & care dealing with an elderly gent, especially regarding the guarantee (so both myself as his son & he could have a copy) was amazing. I genuinely did not believe service like this existed any more. Lovely people to do business with & a company I can thoroughly recommend."
