Fortis door glass is always triple glazed, laminated on both sides for security and SoftCoat low E internal pane argon filled for energy efficiency. Our units are fully wet sealed with warm edge spacer bar. Our glass units are 66mm thick and are specially made by hand in the UK.

We think our glass is the most secure standard option glass on the market in the UK on domestic products, furthermore, Fortis glass units are among the very best for heat retention.

We have many finishes available from the ever-popular clear and satin to more unique obscured glass finishes such as Pilkington Linea.


Fortis doors can be specified to incorporate subtle yet striking LED lighting in the rear of the handle, to the header of the frame or inside the handle in the case of recessed handles and can be controlled via a switch, sensor or timer.

Sidelight & fanlight glass

Our 44mm sidelight glass is triple glazed and laminated for security to both the internal and external faces. Offering high levels of insulation in line with the door and door glass. Our sidelights and fanlights are always supplied joined for minimal frame sight line and for the strength and integrity of a one-piece frame unit.



Our glass units can be blasted to achieve a personalised pattern or to incorporate a house name or number. Speak to your Fortis doors dealer for a full visualisation.
