Southampton based fabricator of modern bi-fold doors

Riverside Bifolds Ltd offer the latest generation of uPVC and aluminium doors. They are fabricated in our Southampton factory, ensuring quality control is consistent throughout.

We fabricate our bi-folds using two market leading systems; Eurocell’s Aspect and AluK’s BSF70. Whether uPVC or aluminium, our doors include market leading designs with style and function that lasts for decades – we believe so much in the quality of the doors fabricated from these systems that we offer a 10-year guarantee on all bi-folds.

Contemporary design and modern performance

uPVC bi-folds are the more cost effective option and are easier to install, with aluminium being more suitable for larger panes of glass and for slimmer sightlines. Both have impressive technical designs which are summarised below (learn more on the technical or individual product pages).
All of our glazed bifold doors come with ‘A’ rated glass and a thermally efficient design as standard, so impress customers with guarantees of improved energy efficiency, thanks to warm edge spacers, argon gas filled units and soft coat solar control glass.

Huge range of colours and configurations

Both our uPVC and aluminium bi-folds are available in a wide range of colours and configurations designed to fit virtually any space, so your customer can turn their outside area or conservatory into a stunning centre piece, whether they have a lot of space to play with or want to make rooms feel more spacious and airy.
