Ultra Slim 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 Patio Door’ is our most popular product, offering the thinnest frames in there class of any fully retractable patio door system in the UK.

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 slide and fold. 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.

The ‘Ultra Slim Patio Door’ is the first in its class as a fully retractable patio door with 19mm coated aluminium side frames and, therefore, more glass for viewing when doors are fully closed. Our Aluminium Slimline Sliding Doors stack neatly to the side of the opening, making more space available to walk through from home to garden than with conventional sliding patio doors.

Are Ultra Slim Bifold Doors suitable for you?

Ultra Slim Bifolding Patio Doors can be used as an alternative to traditional bifold patio door systems. 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.

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.
