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 you can specify

Single, double or multi-leaf layouts for wide openings
Folds into a stack typically around a sixth of the opening width
Galvanised or powder-coated steel, or aluminium for lighter duty
Key-operated lock box on the leading edge, with optional extra locking points
White, black and anthracite as standard, other RAL colours to order
Top-hung or bottom-running versions to suit the floor or sill

What to think about first

Security level

Domestic grilles suit most homes. Shops, pharmacies and high-value stock may justify heavier sections or a third-party certified product.

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.

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.

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 Swanley: questions

Can you survey in Swanley and nearby towns?

Yes. Surveys in Swanley, Bexley, Dartford and elsewhere in Kent are booked around installer availability.

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.

Do retractable grilles need a bottom track?

Most do, because the bottom track stops the grille being pushed out of line. On doorways a low or recessed track can be used to reduce the trip hazard, and some top-hung designs work without one on smaller openings.

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.
