Single Glazed Doors Technical Specification

Our single glazed doors are perfect for internal use, balcony enclosures, commercial partitions and room dividers. Using high quality components and safety glass, they come with high performance and long-service life. 

Single glazed doors don’t rely on the more stringent thermal and other specifications of our double glazed exterior patio doors.  However, we design and manufacture your doors to give the best possible user experience wherever you choose to have them in your home.

Design Specification

On Single glazed units, all glass used is 10mm or 12mm toughened with BS Kite mark and is polished on long edges. Schlegel is fitted between doors or you can have a clear PVC seals, which give a complete weatherproof seal. The tracks and profiles are made of aluminium produced in the United Kingdom.

The profiles on doors are connected to the tracks by means of a flag, including spacers which slide inside along the tracks. The tracks contains top and bottom turning mechanisms which automatically tell us where the doors are to open. Doors can only be opened at gates, which are 6mm by 5mm, which makes them extremely secure.

The door locking mechanism is a stainless steel (satin or polished) privacy lock or a poppit which is opened by pulling a clear acrylic bar towards you.

The framework is produced from powder coated aluminium, manufactured in the UK and can be supplied in any RAL colour you specify. The sides are sealed with a grey PVC plastic.

How our single glazed doors slide and fold. 

All doors slide on PTFE (Pure Teflon), and all the weight is at the bottom, it doesn’t hang, there are no wheels, and it slides by kinetic energy. You can only open the doors when they are in the correct position at the gate, which are in the first door opening only and are 6mm wide x 5mm deep. There is a turning mechanism in the top and bottom track, on which the flags fit into. This allows you to open each door as it automatically touches and locks into position. Once open the doors stack neatly side by side with just 5mm between each door, with the profile being 40mm wide. Doors can stack all one side or both sides any combination.

Brilliant After Installation Service

Our FGC sliding doors were installed in May 2018.
Although we have had two relatively minor problems – neither of which stopped the doors from working – FGC have attended very promptly to carry out remedial action.
Excellent customer service from head office and excellent service from install technicians.

Dear Frameless Glass Curtains, I would thoroughly recommend anyone to use your company. Your product is excellent and the installers were delightful: on time, tidy, quick, cheerful. An initial problem was dealt with immediately. The doors have changed how I feel about living in my small house; they have made the sitting room feel double

A great job

Hi,
I would like to say that your work crew were really nice people and did a great job !!

Cheerful with a ‘can do’ attitude

FGC fitters Mick and Baz arrived at 0754hr ready to begin work. They were polite, helpful and fitted in seamlessly with the existing project team responsible for the restoration of this significant village property. The boys worked without fuss, cheerful with a ‘can do’ attitude taking the time to explain the system as they fitted

After researching the market for a contemporary sliding minimal frame patio door, we were delighted to come across Frameless Glass Curtains. We were so pleased with the doors we ordered another set for the dining room and were not let down – the service we received was consistently good from staff both in and out

Our Frameless Glass walls

Putting a frameless glass walls between our South facing lounge and dining room conservatories was one of the best things we have ever done in our house. When shut, they keep out the cold in winter and, most importantly, the heat on very hot summer days. When open during sunny winter days, the heat warms

Minor Problem Addressed

A strip of the furry trim at the top of the frame that the doors run on had come loose. On the one hand the sort of thing that one could have a go at fixing; on the other hand having witnessed the care and attention the FGC installation team do their work; I thought
