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.

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.

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

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.
