Retractable security grilles in Hounslow

What is the price of retractable security grilles in Hounslow?

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.

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.

This type of grille suits:

Shop windows and glazed shop entrances
Office receptions and glazed partitions
Back doors, French doors and patio doors
Ground-floor windows of homes and flats

Questions we will ask at the survey

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.

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 Hounslow: questions

Can you survey in Hounslow and nearby towns?

Yes. Surveys in Hounslow, Isleworth, Heston and elsewhere in Greater London 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.

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.

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.
