Protect your home or business from break-ins, accidents, and harmful UV rays with professional-grade security window film
Security window film is a transparent or tinted polyester layer applied directly onto your existing windows and doors. Once installed, it creates a strong barrier that makes it harder for intruders to gain entry, often slowing them down to the point where they give up and look for an easier target.
Beyond deterring break-ins, the film also protects you and your family from flying glass shards caused by accidents, stray objects, or severe weather. Available in different thicknesses (7–15 mil), security films are engineered for strength and can be used in both residential and commercial settings — from protecting storefronts against smash-and-grab theft to adding safety in homes with children.

| Break-in Resistance | Delays entry; holds glass together | High (laminated) / Medium (tempered) | High visual deterrent; can be bypassed | No physical barrier (detection only) |
| Shatter Safety | Yes; retains shards | Yes (laminated) / No (tempered shatters small) | N/A (glass still breaks) | N/A |
| UV / Heat Control | Up to 99% UV; optional heat rejection | Limited UV; varies by glass spec | No | No |
| Aesthetics / Visibility | Discreet (clear or tinted) | Looks like standard glass | Intrusive; changes façade | Invisible hardware; no visual change |
| Maintenance | Low; standard glass cleaning | Low–medium; like normal glazing | Medium; rust/paint, cleaning | Medium; batteries, sensors, monitoring |
| Best For | Homes/shops seeking discreet physical protection | High-risk sites, new builds, code compliance | High-crime areas where visual deterrent is OK | After-hours monitoring & insurance requirements |

faq
Yes, it is removable, but removal is best handled by professionals to avoid damage to the glass.
Some bubbling from trapped moisture is common right after installation—it can take up to 60 days to fully evaporate. Avoid pressing bubbles, which can prolong drying.
For homes: 7 or 8 mil films are common. For high-risk areas like schools or storefronts: 8 or 14 mil options provide more protection.
Security film does not stop someone outright, but significantly delays forced entry and holds shattered glass together, reducing injury risk.
Some manufacturers misleadingly claim bullet resistance, but reputable sources like 3M clarify that the film does not stop bullets.
How do I clean it?
Use a microfiber cloth and ammonia-free cleaner. Wait until the film is fully dry (up to 60 days) before cleaning.
