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.
What you can specify
- Works with uPVC, aluminium, timber and steel windows
- Anti-tamper fixings into masonry or a fabricated subframe
- 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
- Quick-release escape handle for bedroom and upstairs windows

Things to decide before you order
Retractable, fixed or removable
Match the grille to how often the window opens. Daily-use windows suit retractable; never-opened windows suit fixed; occasional windows suit removable.
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.
Rules that apply in 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 Coleraine: questions
Can you survey in Coleraine and nearby towns?
Yes. Surveys in Coleraine, Ballymoney, Limavady and elsewhere in County Londonderry are booked around installer availability.
Do grilles work on bay windows?
Yes. A bay is usually treated as separate grilles for each face, or one grille following the bay on a curved or angled track.
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.
Can I still open the window with a grille fitted?
With a retractable or removable grille, yes. Many fixed internal grilles also leave room to open the sash or casement behind them.
