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

Galvanised or powder-coated steel, or aluminium for lighter duty
Key-operated lock box on the leading edge, with optional extra locking points
Single, double or multi-leaf layouts for wide openings
Vertical bars with diagonal scissor links that lock rigid when closed
Folds into a stack typically around a sixth of the opening width
Top-hung or bottom-running versions to suit the floor or sill

Fitting in Barnet and nearby

We arrange surveys and fitting in Barnet and across the EN5 postcode district, as well as in nearby Potters Bar (3 miles) and Borehamwood (3 miles). Dates depend on installer availability.

London's buildings range from Victorian and Edwardian terraces and mansion blocks to post-war estates, with long high streets of ground-floor shops below flats.

Typical places for this kind of grille include:

Stockrooms and cash offices
Shop windows and glazed shop entrances
Back doors, French doors and patio doors
Office receptions and glazed partitions

Things to decide before you order

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.

Security level

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

Rules that apply in England

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.

Listed buildings and conservation areas

Listed buildings need listed building consent for works that affect their character, which can include internal grilles and their fixings. In conservation areas, councils look closely at anything fitted to the outside. We recommend speaking to the council's conservation officer before ordering.

Retractable security grilles in Barnet: questions

Do you cover Potters Bar as well as Barnet?

Yes. As well as Barnet, we can arrange surveys in nearby Potters Bar, Borehamwood and Finchley, and elsewhere in Greater London.

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.
