A window security grille is a steel barrier fitted across a window so that breaking the glass no longer gives a way in. It can be retractable, fixed or removable, and is most often fitted inside the reveal where it is protected and barely noticed from outside.

Choices you can make

Retractable, fixed or removable designs
Fitted inside the glass by default; external options for recessed or plain openings
Powder-coated in white, black or anthracite to sit with the frame colour
Made to measure for the reveal, including bays and splayed reveals
Works with uPVC, aluminium, timber and steel windows
Anti-tamper fixings into masonry or a fabricated subframe

County Antrim centres on Belfast's red-brick terraces, Victorian city centre and commercial areas, with towns such as Lisburn, Ballymena and Larne.

Typical places for this kind of grille include:

Flats with windows onto shared walkways
Rear windows facing alleys and gardens
Ground-floor and basement windows
Offices and shops with side or rear windows

Things to decide before you order

Escape requirements

If the window is a designated escape window, the grille must open from inside without a key or tool. We fit quick-release locks for these.

Depth in the reveal

Tracks need a few centimetres of flat reveal. Where the frame sits flush with the wall, the grille can be fixed to a slim subframe instead.

Rules that apply in Northern Ireland

Northern Ireland

Bedroom and escape windows

Fire safety in new building work in Northern Ireland is covered by the Building Regulations (Northern Ireland) 2012 and Technical Booklet E. Where a room relies on a window for escape, nothing fitted over it should stop it being used. We only fit grilles over escape windows with a keyless internal release.

Listed buildings and conservation areas

Listed buildings in Northern Ireland need listed building consent for works affecting their character, with the council deciding and the Department for Communities' Historic Environment Division advising. Conservation areas bring extra scrutiny of external changes.

Window security grilles in Belfast: questions

Can you survey in Belfast and nearby towns?

Yes. Surveys in Belfast, Newtownabbey, Holywood and elsewhere in County Antrim are booked around installer availability.

Will a grille damage my window frame?

No. Grilles fix to the wall reveal or a subframe, not to the window itself, so the frame and its warranty are unaffected.

Are window grilles safe in a bedroom?

They can be, provided the grille has a release that opens from inside without a key. Bedroom and upstairs windows often have to serve as escape routes, so we will not fit a key-only grille over a window you need for escape.

Should window grilles go inside or outside?

Inside in most cases. Internal grilles avoid weathering, are harder to attack, keep the outside of the building unchanged and rarely need planning permission. External grilles suit openings with no internal depth.
