Security film holds broken glass together. When the filmed glass is also attached to the frame, it stays in the opening longer, so an intruder has to keep working to get through instead of clearing the glass in a few blows. No film makes glass impossible to break through. The goal is to make an opening take longer to create.
Under impact, an attached security film system:
- Holds the broken glass together instead of letting it fall out
- Keeps the filmed glass in the frame
- Makes an opening take more time and effort to create
One example from our own work: at an Illinois video gaming location where we installed 8 mil clear Armorcoat with a four-sided DOWSIL 995 attachment, the customer’s security director reported that intruders struck a glass door 18 times with a sledgehammer before getting in. That was reported by the customer, not a laboratory test or a guarantee of performance. Results vary with the glass, the frame, the attachment and the attempted entry. It shows what the system is meant to do: the glass broke, and the opening still took real work. We explain what testing shows in What Security Window Film Can and Cannot Do, and what Illinois Gaming Board rules require and what film adds in Smash-and-Grab Protection for Storefronts and Video Gaming Locations.
