Your Ultra Slim aluminium bifold door system allows for no boundaries between your interior and exterior living space. As your bifold doors open they leave a seamless world between home and garden, flooding your lifestyle with the tranquility of nature in a contemporary arrangement of both style and efficiency.

The original bifolding door systems manufactured in and for the UK were of unplasticized polyvinyl chloride (uPVC) and over the past 20-30 years whilst pleasing to the eye, have been thwarted with operational folding door and cosmetic quality issues due to their plastic material. Not only will your bifold doors open up more space than conventional patio doors but will be much stronger, smoother and reliable with its aluminium bi-fold door frame and unique designed low threshold super-glide roller and track system.

A British manufactured bi fold door system means that there are no lengthy lead times, in fact we will endeavor to work with in your lead time, and with a quality ten year manufacturer’s guarantee on the Ultra Slim bifold doors, you can rest assure that you will enjoy your new bifold doors with peace of mind.

Another advantage to being manufactured in Britain means that your bi fold doors not only have been precision engineered and constructed with the finest quality materials to the highest of standards, but also have been produced with you and your family’s safety and security always as the number one priority. Your bifold doors come with a lock out track which enables your door system to be opened anywhere along its run and bolted for security whilst you enjoy the flow of fresh air into your room controlled by your door lock out position. Safety is the key to any enjoyable family environment and your bifold doors with their finger safe gasket design helps prevent little fingers getting trapped.

Let us not forget that the most impressive specification of this Ultra Slim folding door system design is the equal sight lines of 110mm at adjacent doors (interlocking mullions) and the complete frame recess, this is achieved by the slim 50mm aluminium frame width.
