Slimmest Bifold Patio Doors in UK. 35mm Sightline. Fully installed in 4 weeks.

Ultra Slim Bifold Patio Doors

We are a family run business and have been trading for over 25 years. We design, manufacture and install our range of glass doors nationwide. The revolutionary ‘Ultra Slim Bifold Patio Door’ is our most popular product, offering the thinnest frames in their class of any fully retractable patio door system in the UK, with a total sightline of just 35mm.

Vision Glass Doors’ UltraSlim sliding doors are different. Why? Because they look like bi-folding doors when they are open and when they are closed but they do not concertina. Instead, there is a main door that opens normally and each of the other doors will slide along the guides and pivot open, stacking at the side.

Additionally, unlike bi folding doors, you can slide each door along the guide and just leave it wherever you want to, leaving gaps between the doors to allow air flow through – see examples in our photo gallery.

Our Ultra Slim Bifold Patio Doors are the first in their class as fully retractable patio doors with 19mm powder coated aluminium side frames, making them a great bifold door alternative if you prefer thinner frames and a less obstructed view when the doors are fully closed. Our bi folding sliding glass doors stack neatly to the side of the opening, making more space available to walk through your home and into the garden.

As an alternative to our Slide and Turn system we also offer Slimline Sliding Patio Doors.

Are Ultra Slim Bifold Doors suitable for you?

Ultra Slim Bifolding Patio Doors can be used as a modern alternative to traditional bifold doors for a patio. They can be used for room dividers, balconies, swimming pool enclosures, garden offices, outbuildings, verandas and even shop fronts.

Our ultra slim bifolding door surpasses all UK building regulations and offers unbeatable U value ratings due to the amount of glass used. Glass is more thermally efficient than aluminium, so the smaller the frames, the more money you save on heating! As standard our slim framed bi-folding door uses ‘K’ toughened double glazed glass. But we offer many many variations to this such as integral blinds or triple glazing. Our Bi Folding Sliding Glass Doors are the next generation of outside sliding doors. Traditional Bifold Doors for Patios have now been replaced by our revolutionary Ultra Slim – Slide and Turn system.

Why would you choose a traditional bifolding or sliding patio door when you could have slimmer frames which offer unbeatable clear glass views? If price is an issue, think twice, as our door systems use much less mechanical materials, therefore the cost of manufacturing is also cheaper. A modern alternative to the limited functionality of outside sliding doors.
