Design Specification

Our unique extrusions, side columns, tracks and profiles are all manufactured in the UK, as are our Frameless Doors. All units are manufactured to comply with BS6375 Part 1 2004.

The profiles on doors are connected to the tracks by means of a flag, including spacers which slide inside along the tracks. The tracks contain turning mechanisms which automatically tell us where the doors are to open. Doors can only be opened at gates, which are 13mm by 5mm, which makes them compliant to PAS24. The side columns expand by turning an internal handle, which in turn pushes the doors together to provide a weatherproof seal (wind and rain) BS6375 Part 1 2009.

How our doors work.

All doors slide on our purpose designed wheel system so the majority of the weight is at the bottom. Therefore, no additional reinforcing is required at the point of installation. Once the main working door is opened, the remaining doors then slide, stack and fold in the same location. As all doors are slim-line (45mm), they only take up a small amount of space. Our Frameless Doors can be stacked to either one or both sides of the opening, or a combination of the two. They can be opened inwards or outwards.

The door locking mechanism can only be accessed from the inside and uses a key situated within the handle for security purposes. There is no locking mechanism on the outside. When opening the main door, just turn the key and handle – the door will automatically spring back to allow you to open and close the door.

The framework is produced from powder-coated aluminium, manufactured in the UK and can be supplied in any RAL colour you specify.

What our customers say

MR VH, Essex

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’.

A great job

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

HP

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

Professional, diligent and friendly with it

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,

All in all a very good experience with FGC

Thanks you for everything FGC did on this project for us.  We found you from an on-line search which doesn’t always identify helpful or committed suppliers, especially where the requirement is small or simple as this one was..  FGC were both helpful and committed.  Thank you especially for progressing things much quicker that the weeks
