What Are Crime Screens?
CrimeScreen® are robust, retro-fit security systems designed to protect vulnerable glazing from intrusion, damage, and everyday impact. Installed externally, they act as a discreet yet powerful barrier—enhancing both security and peace of mind without compromising appearance.
6 mm clear Polycarbonate CrimeScreen®
220x times stronger than glass.
2mm perforated steel CrimeScreen®
Protection with ventilation-through, almost invisible from the internal side of the glazing.
Safety Without Compromise
Security without prison-like steel bars or gates.
Made to Measure
For the perfect fit and first-time fitting.
A Simple Idea. A Powerful Solution.
Designed with both strength and visibility in mind, they allow natural light to pass through while reinforcing your property’s weakest points.
Smart Protection. Simple Design.
01
The Strength Behind Polycarbonate.
Our UV‑protected polycarbonate inserts are 200× stronger than glass and 50% lighter, giving you a crystal‑clear barrier that doesn’t crack, shatter, or weaken under force. Unlike traditional glazing, the polycarbonate flexes under attack — absorbing energy instead of breaking. It’s the same material used in high‑security environments, now adapted for everyday buildings that want discreet protection.
02
Perforated Steel That Lets Light In
For customers who want maximum strength with airflow and visibility, our perforated steel option uses 2.2 mm galvanised Zintec sheet with precision‑cut 4 mm holes. It allows 65% of natural light through and is almost invisible from the inside. Double powder‑coated for durability, it stands up to weather, vandalism, and repeated impact without bending or buckling.
03
The Frame That Makes It All Work
Every CrimeScreen is built around a 40×25 mm aluminium frame engineered to handle real‑world attacks. Inside the frame sits an impact‑absorbing compression gasket — a flexible buffer that allows the polycarbonate or steel to move under pressure without popping out. This is what makes CrimeScreen different: the system works as a single, integrated unit, not just a sheet held in place.
04
Designed to Look Like Part of Your Building
Security shouldn’t make your property look hostile. CrimeScreen is intentionally designed to be discreet maintaining the original appearance of your windows while adding a hidden layer of protection. No bars. No shutters. No visual clutter. Just a clean, modern finish that keeps your building welcoming and secure.
