Protective security
Martyn’s Law and protective glazing support
Practical glazing upgrades that can support a wider, risk-led protective-security plan for publicly accessible premises.
Risk-led specification
Glazing considered as part of the premises
The Terrorism (Protection of Premises) Act 2025—commonly called Martyn’s Law—focuses organisations on proportionate protective security and preparedness. Current Home Office statutory guidance says the substantive requirements have not yet commenced. Where a premises assessment identifies glazing as a vulnerability, a properly specified safety or security film system may form one physical mitigation within a wider plan.
- Clear safety and security films
- 100, 175 and 200 micron specifications
- Edge-retention and attachment options where required
- Occupied public, retail, education and workplace sites
- Out-of-hours and phased installation

Film is not a stand-alone Martyn’s Law certificate
No window film alone makes a premises compliant. Product, glass, framing, anchoring and the wider security plan must be considered together against the project’s risk assessment and professional advice.
