Smash-and-grab is a timing problem. Plan for the minutes you control.
Think in sequence
Before asking for bids, use the storefront specification guide to agree on permissions, quantities, attachment and handover.
A typical smash-and-grab relies on breaking glass quickly, reaching or stepping in, and leaving before anyone responds. Every layer you add targets one step of that sequence:
| Step | Layers that address it |
|---|---|
| Detection | Glass-break and contact sensors, monitored alarm, camera coverage |
| Breaking through | Security film with frame attachment, door hardware, bollards or planters for vehicles |
| Reaching goods | Display layout, lockable cases, high-value items away from glass overnight |
| Response | Alarm verification, police response, a written incident procedure |
What film realistically changes
Filmed glass tends to stay in the frame as a cracked, held-together sheet, which makes a quick reach-in harder and noisier. With attachment, the pane is less likely to fold out as a unit. Neither guarantees prevention, and no honest provider will quote you a fixed number of minutes. See why frame attachment matters.
Coordinate with your alarm provider
Film can affect how glass-break sensors respond. Tell your alarm company before installation and test sensors afterwards. If you use window graphics or solar film, plan the layering and removal order with your installer.
Practical inventory
- Measure each lite (width × height) and count doors separately.
- Note the frame system and whether stops are interior or exterior.
- Photograph existing film or graphics; aged film must usually come off first.
