Getting the right internal grille for your building
Access control
Hinged grille doors can take electric locks or readers, wired by a suitable contractor.
Partition strength
A grille is only as strong as what it is fixed to; stud walls may need reinforcement.
What the rules say in Northern Ireland
Insurer requirements
Insurers set their own conditions for business premises, stock and cash. If your policy names a type or rating of grille, get the wording in writing before ordering.
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.
