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.

Single Glazed Doors Technical Specification

Glass – 10mm or 12mm Toughened Glass Polished all-round. British Standard Kite Marked. Schlegal is fitted as standard between glass or alternatively clear PVC for better weather performance and weather sealing. Sound proofing effect of approximately 70%.

To open and close doors – You can have either stainless steel lock or a poppit which is opened by pulling a clear acrylic rod.

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.

FGC installed a two-panel frameless glass door at our property yesterday. Wow!! the installation is exactly as discussed, and was carried out by two of FGC's team members who were so professional and courteous. They were excellent, and we have no hesitation in recommending FGC and their team to anyone considering such an installation.We are delighted with the installation, and very pleased we chose FGC.Well done FGC!!

We purchased a beautiful Origin sliding door and side window from FGC. FGC installed the sliding door and window on time, however the sliding door did not fit correctly. Issues can happen. FGC made the process of re-surveying and re-installation very simple. FGC is a very pleasant and professional company to deal with. We are very happy with their service and would strongly recommend them.

Excellent planning and product advice. All the staff were polite courteous and friendly.On the day of the installation, the team arrived bang on time -we live in Wales so a long drive from Kent! They had the job done by lunchtime (fitting a sliding patio door) and I have to say that on first impression of the unit, it looks and feels like solid quality.

We had a 5m stretch of these wonderful doors installed several years ago and have been very happy with the uninterrupted view of the garden that they allow from the living room. They are admired by every tradesman who sees them. A minor problem we experienced with water ingress last year was promptly and effectively resolved, and the doors were serviced for free at the same time.

We love our new kitchen windows fitted by FGC - we particularly chose them for their slim frames. Their service has been excellent throughout, including on a recent maintenance item. We would highly recommend them.

What our customers say

Mr A B

We are very pleased with the glass curtains, which do what we want them to – separate the house and conservatory, meeting building regs, but as unobtrusively as possible. We were very happy with the service we received and the efficiency of those who fitted the curtains and we would have no hesitation in recommending

Professional and Efficient

We had FGC doors and windows installed in our house in May 2019. From our initial enquiry through to installation everything was handled very professionally and with attention to detail. The doors and windows themselves are excellent quality and definitely enhance the house. The fitters who carried out the original installation were very good and

Customer Service

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

Very Happy with our doors

Thank you again for the doors, we’re very happy with them and, once the renderer has finished (hopefully tomorrow), we’re really looking forward to removing the plastic protection so we can see through them properly. Mr B, Brighton

Doors look great

I like to confirm that the performance on site was excellent and the lads where very polite and helpful. The doors look great, all we have to do is to undertake all the finishes around the framework. 20160525

Frameless Glass are one of the most impressive companies I have ever come across

This company have a product which to my mind is “second to none”. Their glass doors really let you feel you are outside as they have the tiniest of joins…I used to know the exact cm measurement! I was initially worried though about what would happen on follow up problems as their main office is

I was very impressed with your facilties and how all the aspects of my purchase were explained. Your installers were thorough and polite and finished off the installation well, and would have no problem in reccommending you to others. Your aftercare was very good and prompt. All in alll very impressed with the doors and

Scrimgeour

As to how we were from initial contact (were we polite)? Yes a bit abrupt especially the on site visit. Arranging installation (were we on time and on schedule) Excellent. Were we clean and tidy? Good but the windows were left uncleaned so difficult to check for scratches. VG at organising a company to deal

Looks even better than we imagined

Your fitters have just left and we are very pleased with the installation, the door looks even better than we imagined and the guys were really professional. Looks like we will go ahead with the other one. However, we will wait awhile till we are sure it will look ok as it is a taller

STUNNING!

FGC patio doors have replaced Georgian windows overlooking my garden, bringing the outdoors into my upper ground living room all year round. Opening out onto a balcony with steps down to the garden, they’ve transformed the whole flat. Elegant and easy to use, they also let in loads more light and keep out far more
