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.

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 Wales

Wales

Grilles in rented homes

Under the Renting Homes (Wales) Act 2016, landlords must keep dwellings fit for human habitation, which takes fire hazards into account. Grilles over windows a contract-holder may need for escape should open from inside without a key.

Grilles inside the glass

A grille fitted inside the glass does not normally need planning permission in Wales, as it does not materially change the outside of the building. If the building is listed, listed building consent may still be needed.

Window security grilles in Caernarfon: questions

Do you cover Bangor as well as Caernarfon?

Yes. As well as Caernarfon, we can arrange surveys in nearby Bangor, Pwllheli and Holyhead, and elsewhere in Gwynedd.

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.

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.

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.
