We recommend bi-fold doors to open outwards, saving space inside your home and improving weather resistance.

External aluminium cill
Most doors require an external cill to drain water away correctly. If you already have a stone or tiled cill as part of the building you may not require a cill.
85mm stubb cill
150mm normal cill
190mm long cill
Please note: If a cill is chosen, the cill height of 25mm will be included within the overall height of the door.
Thermal upgrade as standard, we use the same high quality 1.22 u rated Pilkington glass as on our windows.
Advanced double glazing Argon filled with 1.22 glass u-rating.
We cannot use triple glazing on bi-fold doors due to the weight and thickness, making the folding difficult. If you need triple glazing, please use our French doors.
Acoustic glazing for significantly better noise insulation.
Pilkington Optiphon™ high quality acoustic laminated glass offers excellent noise reduction without reducing light transmittance and impact performance.
Ideal for significantly reducing noise from road, rail or air traffic, factories or nightclubs.
Noise is reflected back towards the source and also absorbed within the glass.
The glass unit is made of a 6.8mm acoustic laminated outer pane, a 18mm Superspacer void and a 4mm inner KS pane.
Being laminated it is also very secure and difficult to break into.
The u-value is 1.2, the same as our superb A+ rated double glazing.

A frame extender increases the thickness of a door frame at a specified side. Great for properties with deep plaster, render or tiles over tiles.

Extenders simply clip or slide on the door profile as you can see on the picture.

For added decoration or for a traditional feel we have Georgian bars, Square lead or Diamond lead.
Our Georgian bars are 18mm thick and are placed between the glass panes for ease of cleaning. We do not offer external Astragal bars due to unreliability as they are just taped on. We can instead supply a single horizontal or vertical extra bar. More information on the the glass menu pop-up.
Our Square lead is traditional lead which is 9mm thick and is placed on both sides of the external pane of glass.
Note: lead layouts are just a representation, the actual layout will be according to best practice.
Note: For custom or special Georgian/lead layouts, or to match a window with an adjacent door or window, please leave specific instructions as a note at checkout.
