Ultra Slim Patio Doors

Technical Specifications

Our latest addition to our patio door system range is the double glazed ultra slim patio door. Taking the strengths of both the bifold door and frameless glass door, it is the most modern alternative to bulky upvc or aluminium framed door. Fully retractable, 100% weather proof and with an access door as standard, why would you choose a traditional bifolding door?

There is literally no other door system like it, with the slimmest frames on the market, our ultra slim patio door uses a bifold or sliding folding mechanism. The ultra slim bifold or sliding folding door is suitable for all external and internal applications, made to measure, and is fully weather proof using our dynamic weather protection system.

With a frame width of 35 mm, imagine the views…

Our ultra slim bifold 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 bifolding door uses ‘K’ toughened double glazed glass. 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 much cheaper.
