A retractable security grille is a steel or aluminium lattice of vertical bars joined by scissor links that runs in a top and bottom track. Drawn across a window or door it forms a locked barrier; slid back, it folds into a narrow stack at the side so the opening is fully usable.
What goes into a retractable grille
- Top-hung or bottom-running versions to suit the floor or sill
- Key-operated lock box on the leading edge, with optional extra locking points
- Single, double or multi-leaf layouts for wide openings
- White, black and anthracite as standard, other RAL colours to order
- Galvanised or powder-coated steel, or aluminium for lighter duty
- Vertical bars with diagonal scissor links that lock rigid when closed

Things to decide before you order
Which side it folds to
The stack needs a clear wall or reveal to park against. We check curtains, handles, radiators and light switches before the grille is ordered.
Bottom track or no bottom track
A bottom track gives the most rigid grille but can be a trip point across a doorway. Low-profile and removable floor tracks are available for doors.
Rules that apply in England
Bedroom and escape windows
Approved Document B (fire safety) expects many habitable rooms in houses, especially first-floor rooms, to have an emergency escape window with an unobstructed opening of at least 0.33 m², at least 450 mm high and 450 mm wide, with the bottom of the opening no more than 1,100 mm above the floor. We only fit grilles over escape windows with a release that opens from inside without a key.
External grilles and planning
External grilles and shutters on shops and other commercial buildings normally need planning permission from the local council because they change the building's appearance. Many councils' shopfront guides favour internal, open-lattice grilles, particularly in conservation areas.

Retractable security grilles in Northamptonshire: questions
Which towns in Northamptonshire do you cover?
We can arrange work anywhere in Northamptonshire, including Northampton, Corby, Kettering, Wellingborough and Rushden, and in other towns across the area.
How long does a retractable grille take to fit?
Most single windows or doors are fitted in an hour or two once the made-to-measure grille arrives. A shopfront or several openings may take a day.
Can a retractable grille be fitted inside the window?
Yes, and that is how most are fitted. The tracks fix into the window reveal or to a timber or steel subframe, so the grille sits between the glass and the room.
Will a grille stop me opening my windows?
No. An internal grille sits inside the reveal, so you can open the window as normal when the grille is folded back, and usually with it closed if there is enough depth between grille and glass.
