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.

What our customers say

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 problem promptly. FGC are not cheap but they had what we wanted and we’re delighted with

We are very pleased with the freedom the installation affords us with easy access from lounge to dining room. Aesthetically the glass curtain installation is very pleasing. All appears well but we must point out the bottom bar is not firmly fixed in the channel in the floor & moves if one stands upon it. It does not appear to affect the glass curtain function & as we have a 10 year guarantee things can

We have been amazing our friends and family with our FGC since we had it installed a few weeks ago. Every ‘trade’ that is working on site has been fascinated and suitably impressed with the product and engineering. We are over the moon as it has really been the star of our home extension. Thanks too to the installers who were

We had our doors fitted in 2015 and have been very pleased with them. As with most things there are times when an adjustment is required to the doors or in our case a door needing to be replaced as it had developed a problem with condensation. The company has been very good at resolving these matters in an efficient and timely manner. We highly recommend the product which has made a big difference to

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 the glass curtains was the best thing to do for us.  Even though your web site clearly shows them, we

I had been looking for some time to replace my patio doors in our lounge as they had very wide plastic frames and wanted something that wouldn’t restrict the view up the garden I asked to see if it was possible to view some already installed close by. Luckily there was, we went and viewed and was very impressed. I’ve seen lots of companies do bi-fold and there is actually one that is on the

Yes we are very pleased with the doors and would recommend them. Initial contact was done by our neighbour at Kingswood so cannot comment, however, the price we were initially quoted was incorrect and significantly lower than it turned out to be. Not sure why. We at Derwent only had a verbal quotation. The installation was carried out on time, very politely. Unfortunately as you know the handle broke and no spare. Reasonably clean. For
