The Problem
Unanchored film keeps glass together, but a determined attacker can push the whole sheet out of the frame.
High-risk storefronts, schools, and government buildings need the pane itself to stay put.
High-Security Anchoring
Film alone holds glass together. Anchoring holds it in the frame.
Quick Answer
A security film attachment system bonds the edge of security film to the window frame so the entire filmed pane stays in place when struck. Wet-glaze systems use high-strength structural silicone; mechanical systems use metal battens screwed to the frame. Anchoring dramatically increases forced-entry delay and blast/impact performance, adding roughly $5–$12 per square foot in Los Angeles.
Unanchored film keeps glass together, but a determined attacker can push the whole sheet out of the frame.
High-risk storefronts, schools, and government buildings need the pane itself to stay put.
Wet-glaze: structural silicone bead along the film edge — nearly invisible, ideal for storefronts.
Mechanical: aluminum battens fastened through the film into the frame — maximum retention for the highest-risk sites.
We recommend anchoring for LA jewelers, dispensaries, pharmacies, luxury retail, schools, and public buildings.
| Film / System | Thickness | Best For | Installed Cost / sq ft |
|---|---|---|---|
| Safety film | 4 mil | Shard retention, accidental impact, earthquakes | $8 – $12 |
| Security film | 7–8 mil | Homes, offices, ground-floor glass | $10 – $15 |
| Heavy security film | 12–14 mil | Storefronts, smash-and-grab targets | $13 – $18 |
| Film + wet-glaze anchoring | 8–14 mil | Schools, retail, high-risk sites | $15 – $25+ |
| Film + mechanical attachment | 14 mil | Maximum forced-entry delay | $20 – $30+ |
