Information about Frameless Bi folding doors

The all glass bifolding doors available from Frameless Glass Curtains combine innovation, high quality design and sophisticated manufacturing techniques.

the innovative glass bifolding doors from frameless glass curtains have many unique features compared to standard bifolding doors.
The innovative glass bifolding doors from Frameless Glass Curtains have many unique features compared to standard bifolding doors.

With UK and International Patents, these unique glass bifolding doors offer several advantages over typical aluminium bifolding doors.

How FGC’s Slide & Fold Doors Differ

The framing element of the product provides a highly insulated thermally broken frame to the perimeter of the door at the head and sides (jambs) and in conjunction with the threshold.

Each door leaf features an aluminium rail top and bottom only. Unlike other metal bifolding doors there is no aluminium profile to the sides of the door leaves, regardless of how many leaves are chosen.

The advantage of this is that when the doors are closed you are looking through glass and without the obstruction of visible aluminium.  As a result, there are substantial uses for frameless slide and fold doors in both residential and commercial buildings.

Glass Spacer Bar

The double glazed units used in the high standard of construction to make glass bi folding doors is radically different from the double glazed units used normally.  The spacer bar found in any standard high specification unit is replaced with an incomprarable spacer bar made of toughened glass.

This spacer bar despite it’s glass construction still contributes to the impressive U Values of these bifolding and sliding doors giving an centre pane U Value of 1.0Wm2K. The product with the frame achieves an overall U-Value of 1.7Wm2K.    Glass is manufactured with 4mm/6mm Planitherm 4s or soft coat and 4mm/6mm Toughened low iron. The toughened glass spacer which is 20mm x 12mm/15mm/18mm with 45 degree x 8mm mitres are fixed between the long edges of glass. Top and bottom have 2 rows of aluminium 20mm spacer bars filled with desiccant. Profiles are compressed onto glass and fixed with a polymer.constructed from

Unique Door Hardware

It makes sense with a bifolding door made of glass to continue the all glass theme and extend it to the handles. Available is a range of sophisticated door handles that complement the sleek and frameless appearance of the bifolding doors.

Satin Chrome, satin stainless steel and polished stainless steel hardware is also available.

The most compact bifolding doors when open.

On all bifolding doors designed to fold back and depending upon whether all panels slide to one side or each side some space is inevitably lost when the doors are fully folded.  Most customers choose to have their doors opening outwards to save on losing inside space.  On a typical all aluminium bifolding door, you can lose space.  Our compact bifolding doors take up only 180mm on a four pane door – substantially slimmer.

Frameless slide and fold doors are also ideal for use in commercial glazing, such as shops, offices or office partitions.

I contacted Nick @ ATS for guidance on what aluminium sliding door systems would be suitable for an opening in an extension that is going to be both wide and tall. He came back really quickly with very detailed and incredibly helpful advice. He is clearly extremely knowledgeable about the systems on the market and their respective features and capabilities. If you’re feeling a bit lost by the overwhelming range of choices out there, I’d definitely recommend contacting him.

After a lot of research to find doors that would meet our unusual size requirements and feeling increasingly uncertain about the best way to spend our small budget, I stumbled on the ATS website, and I'm so glad I did! I contacted ATS to request advice and Nick promptly replied with a wealth of information, providing us with options and relevant contact details. I only wish I'd found them sooner!

I've been so confused about how to achieve the look I'm after, and going round in circles with various window/door companies, trying to get away from the huge chunks of plastic currently around my windows. I didn't expect an email to a company found through a Google search to really help - but I was desperate, so I tried. I'm SO glad I did. Finally I have clear explanations from ATS of where I've been going wrong, exactly what I'm looking for, and a list of local companies that might be able to provide it! The response has excelled my expectations and I feel as if I'm finally inching closer to a home with which I'll be happy and comfortable: thank you.

It is rare that I write reviews, however after my very positive communication with Nick - enquiring about suitable slim sash aluminium windows for my project, I felt that a review was definitely warranted. I can reinforce the many positive reviews posted so far, Nick was very quick to respond, providing comprehensive detail, with excellent independent advice.In summary, great service, thank you Nick.

I dropped Nick at Aluminium Trade Supply an email re high security slim sightline bi-folds and their alternatives and he responded that quickly (and so comprehensively) that I felt bad I’d not paid him for his time!Nick Sir your product knowledge is outstanding and you are providing a level of service that goes wayyyy above and beyond expectations. I’ll definitely make sure I mention Aluminium Trade Supply to anyone I encounter looking for a fenestration solution 🙏🏼

We are looking to replace some old UPVC patios doors with aluminium ones. The ATS website is a great source of advice in an area where clear information is sorely lacking. Having used the website, I then followed this up with a number of specific questions relating to our search, and Nick came back very quickly with clear, detailed and very useful advice.I have been very impressed with both the website and with Nick's advice. My only regret is that I didn't come across ATS before replacing various windows in 2021 - I'm sure it would have saved me a lot of grief and money! Thanks again Nick.

My experience with this firm was exceptionally good and this is notalways the case as a female, dipping a toe into technical waters.I was spoken too with courtesy and at a level that helped me consolidate what was needed .On top of that I was given a list of companies and places where I could obtain the type of product I needed.I could not thank them enough and would certainly go there again and reccommend others do too.
