E-Sosa – Ultra Slim Patio Doors

Ultra Slim Patio Doors

The latest addition to our innovative door range is the Ultra slim patio door system. This offers a thin 35mm sightline, which is unbeatable in the bi-folding door industry. This means that you can have very clear views, without the need for massive bulky frames. The Ultra slim bifold door takes strengths from the frameless glass door and bi-folding aluminium door, which is in fact a modern take on older traditional UPVC and wooden door frames.

Completely weatherproof, fully retractable and including a standard with an access door for ‘everyday’ use – why would anyone choose a traditional bulky bifolding door? You will not find any other door system like this in the home improvement market. Slimline patio doors offer the slimmest frame width’s out of any other sliding folding, bi-folding, sliding and fixed panel door system. Suitable for use with all internal and external applications the Ultra slim patio door is completely made to measure and also uses our unique weather protection system.

Patio doors with slim frames are now one of the most sought-after bi-folding door derivatives, as they have great usability features being fully retractable as well as giving amazing uninterrupted views. Using thinner frames this actually means you’re U-value ratings will increase, because glass has much better heat retention properties  than compared with aluminium or any other type of metal. Therefore the thinner the frames the better the thermal efficiency, the more your saving on heating bills. As standard every Ultra slim glass door comes with ‘K’ toughened double glazing glass.

Most people assume that the price difference is massive between these and other aluminium folding doors, but this is simply not the case. Why not enquire now and find out exactly how much it would cost you to add value to your home?
