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
- Key-operated lock box on the leading edge, with optional extra locking points
- Single, double or multi-leaf layouts for wide openings
- Top-hung or bottom-running versions to suit the floor or sill
- Galvanised or powder-coated steel, or aluminium for lighter duty
- Quick-release internal handle available where a window must stay usable for escape
- Folds into a stack typically around a sixth of the opening width
Fitting in Truro and nearby
Surveys in Truro (TR1) are booked around installer availability, as they are in nearby Falmouth (8 miles) and Redruth (8 miles).
Cornwall's stock is largely granite and slate cottages, terraces and holiday lets, with many seasonal properties left empty for part of the year.
Typical places for this kind of grille include:
- Office receptions and glazed partitions
- Ground-floor windows of homes and flats
- Back doors, French doors and patio doors
- Shop windows and glazed shop entrances
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.
Inside or outside the glass
Inside is the norm: it is protected from weather, keeps the street view unchanged and usually avoids planning issues. Outside fitting suits recessed doorways and openings with no internal depth.
Rules that apply in England
Grilles inside the glass
A grille fitted inside the glass does not normally need planning permission, because it does not materially change how the building looks from outside. If the building is listed, listed building consent may still be needed.
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.

Retractable security grilles in Truro: questions
Can you survey in Truro and nearby towns?
Yes. Surveys in Truro, Falmouth, Redruth and elsewhere in Cornwall are booked around installer availability.
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.
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.
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.
