A fixed window grille is a welded steel frame of bars bolted permanently over or inside a window. It has no moving parts and no lock to pick, which makes it the simplest and most economical grille for openings that are never used for access or escape.

What goes into a fixed grille

Bar spacing chosen to stop entry while keeping light
Decorative bar patterns available for visible elevations

Made to measure for arched and odd-shaped openings

External grilles last longest when hot-dip galvanised and then powder-coated.

Appearance

On front elevations or period buildings a decorative or slimmer bar pattern may sit better than a plain grid.

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.

Fixed window grilles and bars in Isleworth: questions

Can you survey in Isleworth and nearby towns?

Yes. Surveys in Isleworth, Hounslow, Heston and elsewhere in Greater London are booked around installer availability.

Will fixed bars rust?

Galvanised and powder-coated steel is designed for years of outdoor use. Chips in the coating should be touched up to keep the protection intact.

Do fixed grilles need planning permission?

Internal fixed grilles usually do not. External grilles on front elevations, listed buildings or in conservation areas may need consent, so we check before ordering.

How are fixed grilles attached?

With anti-tamper bolts or resin anchors into solid masonry, or to a steel subframe where the wall is weak. Fixings are positioned so they cannot be reached from outside.
