The short answer
Grilles stop someone getting in through the opening; laminated glass and security film slow the glass being broken. For many homes and shops the strongest answer is a combination: laminated or filmed glass for the pane and a grille behind it for the opening.
What does each one do?
- Grille: a steel barrier behind or in front of the glass
- Laminated glass: an interlayer holds the glass together when struck
- Security film: an applied film that helps hold broken glass in place
When is a grille the better choice?
Where you need a clear barrier that takes tools and time to defeat, such as back doors, shop windows and stockrooms.
When is glass the better choice?
Where appearance matters most and the risk is lower, or where grilles cannot be fitted. Glass upgrades are invisible but give less delay than a steel barrier.
Can I combine them?
Yes. Laminated glass with an internal grille behind it is common in shops.
