14 mil
Interior Security Film
Maximum interior protection
The thickest interior option we install. Holds glass together longer under sustained, repeated impact — ideal for ground-floor windows, sidelights, and rear patio doors.
Three film options
The right thickness for the right glass.
What the film does
More than a security upgrade.
Optically clear
No tint, no haze. Bonded to the inside surface of your existing glass and trimmed close to the frame — your windows look exactly the same from the street.
Holds glass together on impact
A hammer, crowbar, or brick creates a spiderweb crack. The laminated layer keeps shards bonded so an intruder cannot reach through.
Blocks more than 99% UV
The same film that resists smash-and-grab also blocks UV-A and UV-B. Reduces fabric and floor fade and cuts heat gain on south-facing rooms.
Warranty-backed
The film and installation are backed by manufacturer and workmanship warranties. Ask us for details at your assessment.
Anti-shatter safety
If a window does break — storm debris, an accident, an impact — the film keeps the broken glass from spraying into the room.
Compatible with your glass
Tempered, annealed, single-pane, and double-pane glass are all candidates. We measure and spec the right thickness window-by-window during the assessment.
Why this matters · police data
Glass-entry break-ins still drive the rolling monthly count.
Across the GTA, 163 break-and-enter occurrences were reported in June 2026. Residential and commercial windows remain the most repeatedly forced surface.

Interior 8 mil · Interior 14 mil · Exterior 7 mil
Choose the right film for your property.
Interior 14 mil is the thickest option — it holds glass together longest under sustained impact. Interior 8 mil is a lighter, well-rounded fit for most residential windows. Exterior 7 mil is built for the outside surface of the glass, used on sun-facing windows and panes that aren’t practical to film from inside. Every install is backed by a 10-year manufacturer warranty.

Q.01Will the film be visible on my windows?

Q.02How long does a whole-home install take?
Typically one day for an average single-family home. Two technicians, no renovation.
Q.03What about tempered or double-pane glass?
Both are compatible. We assess each window and spec the right film grade on site.
