The pane with no lock

A smashed window is the fastest way in, and the quietest.

Glass is the one part of your home with no lock on it. A single sharp hit and a burglar is reaching through for the latch, often in seconds and without much noise.

Security film does not stop the glass from cracking. It stops it from falling out of the way. The pane holds together in the frame, so instead of a clean reach-through there is a stubborn, noisy sheet that has to be fought, and most give up or get noticed first.

You can't make glass unbreakable. You can make it refuse to get out of the way.

Where glass is the weak point

Cover the panes a hand can reach.

The windows worth filming are the ones close to a latch or low to the ground, sidelights beside the front door, ground-floor windows, and glass patio doors.

Applied wet and squeegeed flat, the film disappears into the glass and keeps doing its job out of sight for years.

A patient half hour

Clean, spray, smooth, trim.

1

Clean the glass

Get the pane spotless, any speck shows under clear film.

2

Spray it wet

Mist the glass and the film with soapy water so it can be positioned.

3

Smooth it out

Squeegee from the center out to push water and bubbles to the edge.

4

Trim the edge

Run a blade along the frame for a clean, near-invisible finish.

No power, no app. A one-time application that protects the glass for years.
Layer your defense

Film on the glass, an alarm on the glass.

The film keeps a smashed pane together so it can't be cleared quickly. The TremShield Alarm sits on the same glass and sounds at 125dB the instant it is struck, so a break is both slowed and heard.

Good to know

Questions, answered calmly

No. The glass can still crack under a hard hit. The film holds the broken pieces together in the frame so the pane cannot be quickly cleared and reached through.
No. It is optically clear and, applied well, is effectively invisible once smoothed onto the glass.
Pick by how many windows you want to cover. The 2 m roll suits a few small panes or sidelights, the 4 m roll covers more windows or larger glass.
It goes on wet like a large screen protector. Clean the glass well, spray, smooth out the water, and trim the edge. A typical window takes about half an hour.
Yes, though it is meant as a long-term application. It can be removed later, which may take some effort and adhesive cleanup on the glass.
