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

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.

Excellent service and product from FGC.I have a glass-box conservatory, built with structural glass about 20 years ago. The 2 sliding doors needed replacing, along with 2 side panels, and I contacted dozens of companies selling conservatory doors and none of them were prepared to install their doors because of the perceived risks of working with structural glass.Then I found FGC who, with no fuss at all, carried out a survey, provided a very reasonable quote for the doors/panels and then installed the doors/panels on the agreed date.Communication with the FGC office was always quick and easy. The surveyor and installation team were efficient and courteous. The product works beautifully.We can now use our conservatory again. Thanks FGC.

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.

What our customers say

People admiring our new porch

We were only at home for one day following the installation. A courier delivering a parcel admired the porch and asked who built it for us. Success I think.   Mrs J, Broadstairs

Mr & Mrs Glasgow – Chalfont St Peter

We are very pleased with our frameless curtains in our dining room and lounge, both of which open out into a conservatory.   Our first contact with you, by telephone, was excellent.  We were invited to look at your glass curtains at your showroom in Chatham which is an hour and a half distant.  Seeing

Look Great and Slide Beautifully

As it happens, we are still sadly not in the house. We should be however at the end of February which will be great! I can however pretty much respond to the below as I have been able to test the doors. 1. Your performance was excellent from what has been reported by the builders.

Brilliant, on time and tidy

I just wanted to follow up as I was in the gallery this morning.  The guys were brilliant, on time, tidy, efficient and they fitted the door perfectly. We are very pleased   20151107

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

First class

We moved last year and wanted to maximise the view right through from the rear to the front of the building, overlooking the river. After much searching we found FGC, who installed internal glass doors between the rooms. FGC were very efficient and although we are in the North they sorted out a subsequent small

From the start to the finish we felt comfortable with your staff and installers. It was a product just as we had hoped and envisaged for our new House double glazed, frameless glass doors in 4 openings! Perfect. The doors are a talking point and every body comments on how good they look! They are

Evvy Edwards, Cambridge

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

With competence and courtesy

Unit has been replaced thank you, once again I find FGC have responded to a problem with a no quibble replacement, it is good to know that there is still companies left who honour their guarantee in the proper manner and send installation teams that carry out their work in a professional manner with competence

Mr D

I am very happy with the doors

I am very happy with the doors – I saw them last night after work – though I didn’t open them as I wanted to make sure I followed the installers’ instructions not to. They look wonderful and my boyfriend and mum tell me they were absolutely lovely chaps. The finish seems brilliant and appears to

Gemma Alashe, Chiswick

In short, the product offered by Frameless Glass Curtains is nothing short of excellent. These frameless glass doors are a truly unique system that are really aesthetically pleasing and unlike any other product we could find on the market. The doors are very sleek and elegant and create real impact and wow factor. Our experience

Mr BG

Basically the installation itself was done pretty quickly and efficiently – three guys turned up early in the morning and were done by lunchtime. Polite, tidy. 20150112
