Ultra Slim Patio Doors

Slimmer than any bifold and more functional than a sliding door, our ultra slim patio doors redefine elegance and functionality. Designed, tested and made by Frameless Glass Curtains, our brand new thin-framed patio doors come with the slimmest 60mm sightline at the mullions, nearly half the visible frame of the leading bifolding doors.

Ultra slim patio doors – maximum glass, minimum frame.

  • The thinnest sightline where the doors meet – just 60mm.
  • Tested to PAS24 security, fully sealed, and weather tested.
  • Creates minimalist steel-look patio doors.
  • Suits existing or new build openings.
  • Matching single and double doors.

The Slimmest Slide and Fold Patio Doors

The smallest 60mm sightline for unrivalled views.

Our unique ultra slim patio doors transform any room with minimalist, more versatile doors, designed to be discreet yet functional closed and give you a better experience than a bifolding or sliding door when open.

The styling of our doors, expertly designed, tested and manufactured by us, is one of the most minimal on the market. A slimline surround frame, a lower track, and thinner door rails combine with even thinner vertical frame profiles with a mere 60mm sightline. The result is a door with more glass, a less visible frame, a cleaner look and beautiful styling. The ultra-slim door design gives you the same features as our equally remarkable frameless doors but in a fully-framed option.

The most functional and versatile patio door

With its sophisticated slide-and-turn design, you benefit from the minimalist styling of a sliding door, but better because you have the whole structural opening available when the doors are opened. And our doors are more functional than a bifold because they let you place garden or room furniture on either side of the doors – something you can’t do with a regular bifold. In the closed position, the convenient traffic door, built into the design, lets you use your new doors just like a standard door without folding or moving the other panels. And you can separate the panels to create ventilation gaps without opening the doors.

Reliable security and weather protection

We’ve thoroughly tested our doors to give you peace of mind security to the latest PAS24 security standards when specified with laminated safety glass. Advanced weather protection and sealing ensure your home stays warm and dry during the winter. Our sophisticated high-specification safety glass units and thermally insulated frames help lower your energy bills and meet current Building Regulations.

Ultra slim patio doors by Frameless Glass Curtains come with a flawless build quality, fit, and finish, in over 150 professionally applied colours and finished off by contemporary designer door handles.

The advanced glass comprises clear toughened safety glass, Argon gas fill and Planitherm 1, achieving U-Values as low as 1.2Wm2K with a double glazed unit and an impressive 0.8Wm2K with enhanced triple glass. 

When upgraded to laminated glass, our doors have passed PAS24:2022 securing testing. 

Panel sizes of up to 1000mm wide and up to 2500mm high. 

60mm sightline between the individual panes, consisting of 2 x 26mm aluminium profiles on each door and an 8mm grey PVC bubble gasket. Frame head face dimension of 117mm, standard bottom frame face dimension of 124mm, side frame face dimension of 113mm. The low threshold option creates a threshold height of just 5mm.

A steel-look version is available using 31mm astragal bars.

Choose from single or double doors creating minimalist side or back doors, or the slide and fold design from three to eight panels, including fixed or open corner designs. Our steel-inspired design gives you some of the slimmest doors in the industrial style and even distinctive bifold windows. And because only we design, make, fit and support our products, you’re promised a personal service, a professional installation and a quality guarantee.

We also offer a full range of aluminium windows, bifolding and sliding doors,
and front doors as FGC Bespoke Aluminium.

Dealing with FGC has been a straightforward and hassle free experience from start to finish. I had several queries long before placing an order and FGC were always prompt and helpful with the responses. Then at site survey time they attended on time, with courtesy calls leading up to the appointment to keep me advised, the surveyors were very knowledgeable and again helpful. This gave me great confidence that I’d made the right choice by

I have to say that although I was not on site to see the finished result, the photographs of the work is remarkable and to add to that compliment, our master builder Chris Seviour reported back to me yesterday that he was so impressed with your team and with the final result. Thank you all for such a tremendous job – I’m hoping to have an article written in Country Living about the house later

Claire Menzies
I am really impressed with the finished product and service e provided by FGC. I had an image in my mind of how I wanted the end result to look. The “invisible” glassing was the most difficult and important part to source. FGC came through with flying colours, right from the initial contact, design and survey discussions, to the installation visits. FGC have been superb at meeting my requirements and timescales. The fitting was carried

David, Surrey
We are both delighted with the FGC product and have no issues with any future viewings. From our perspective the “outside has truly come inside”, we use the decking on a daily basis as the FGC curtains have transformed the house which I think adds a significant value to the property. The only trouble now is that when we see home improvement programs such as Grand Designs where they suggest using bi-fold doors we end

I contacted FGC to try and marry up a few weather strips to replace old one’s which I have already fitted on glass curtains. The glass curtains were not supplied by FGC and the company who supplied them, when asked for replacement weather strips just said “we no longer have these in stock and not sure if we can still get them”. FGC requested pictures of the seals and sent some samples free of charge

The service I received from FGC was professional and prompt from the initial on site survey through to installation and completion. Added to this the finished product has exceeded my expectations. It has enhanced my home with style and individuality, and enabled me to make use of the space in a way that is ‘unique’.

The door looks excellent and we’re very pleased with the

Mr H, Wales

“Thank you again for a great installation, we are really enjoying the extra light.” I will be sending a load more images your way at some point

Mr T – Woking

Thank you for a good job even though there were a few issues along the way. Chris and I will have no hesitation in recommending your company, products and services to others. Kind regards Mike and Chris Rodwell
