Shatter-resistant safety film that holds glass together on impact — protecting your home or business from break-ins, vandalism, accidents, and blast events. Free consultation in Calgary.
Standard glass, when broken, shatters into fragments that collapse inward or fall away — creating an instant opening and dangerous shards. Security window film is a thick, optically clear polyester film applied to the interior glass surface using a strong pressure-sensitive adhesive. When the glass is struck, the film holds the fragments together, keeping the broken glass bonded in the frame rather than collapsing inward.
The adhesive layer is the critical component. It bonds directly to the glass surface and maintains its grip even when the glass beneath it fractures. A would-be intruder cannot simply punch through a filmed window — they must continue striking the glass repeatedly, and each blow encounters the same resistance. For smash-and-grab criminals, who rely on speed and instant access, this resistance is a powerful deterrent. Most opportunistic break-ins are abandoned within 60 seconds if entry is not quickly achieved.
Security film can also be combined with attachment systems — mechanical bonding devices that anchor the film edges to the window frame — for maximum glass retention in blast mitigation or high-security applications.
The right film thickness depends on your security goals, property type, and risk profile.
Accident & Basic Impact Protection
Standard safety film at 4–8 mil thickness holds glass fragments together when a window breaks accidentally — from a ball, a falling object, or a storm. It dramatically reduces the risk of injury from flying glass shards and is commonly installed in residential settings, particularly in homes with children, near playgrounds, and in rooms with large glazed areas where accidental impact is a concern. It also meets building code safety glazing requirements in many jurisdictions.
Common applications
Break-In Deterrence & Smash-and-Grab Protection
Mid-weight security film at 8–14 mil is the standard choice for residential and commercial break-in deterrence. This thickness significantly delays forced entry through glass — adding 30 to 90 seconds to a smash-and-grab attempt, which is often enough to cause an intruder to abandon the attempt entirely. The film holds glass intact under repeated impact, turning your standard window glass into a serious barrier. Combined with perimeter alarm systems, it creates a comprehensive deterrence layer.
Common applications
Commercial, Institutional & Blast Mitigation
Heavy-duty security film at 14 mil and above is engineered for commercial and institutional applications where glass integrity is critical. At this thickness, film provides substantial resistance to sustained forced entry, blast pressure wave mitigation (relevant for government buildings and critical infrastructure), and seismic protection by holding glass in frames during structural movement. Often installed with an attachment system that anchors the film to the window frame for maximum retention.
Common applications
Most smash-and-grab break-ins take under 60 seconds. Security film makes glass resistant to repeated impact, buying critical time and deterring opportunistic intruders who expect instant access.
When glass breaks, security film keeps shards bonded together, dramatically reducing the risk of laceration injuries to occupants from storms, accidents, seismic events, or forced entry attempts.
Security film is optically clear and nearly invisible once installed. Most people cannot tell a window has been filmed. It does not darken your glass or affect natural light transmission.
All our security films also block up to 99% of UV radiation, protecting interior furnishings, flooring, and merchandise from UV fading — a useful bonus in Calgary's high-sunshine climate.
