Security Film for Windows
Our security film for windows is sold in 8 mil, 12 mil and 16 mil. The film reinforces the glass in windows, doors and shopfronts and works as a barrier against forced entry. It stays clear — the 8 mil transmits 84% of visible light (VLT), the 12 mil 82% — so from the street the window looks untinted. Both thicknesses block 99% of UV radiation and have a scratch-resistant hard coat above 2H.
Where Security Film for Windows Is Used
- In residential areas, safeguarding houses, bungalows and apartment complexes
- Protecting commercial properties in areas prone to crime
- Strengthening glass in public venues
How Security Film for Windows Works
Glass resilience
The security film for windows makes the glass much harder to break through. Under a heavy blow the pane can still crack, but it holds together as one sheet, and that is what costs the intruder time.
Resistance to repeated blows
Continuous striking creates a spiderweb effect rather than total disintegration. The adhesive layer of the security film for windows binds the broken pieces, so the opening stays closed.
Choosing the Thickness of Security Film
Thicker film means more resistance to impact, and it also means a stiffer material that takes more work to lay down. Choose by the size and the exposure of the glass rather than by the largest number available.
As a rule, the bigger and the more reachable the pane, the thicker the film worth putting on it. Both thicknesses we stock are clear, so going thicker costs you almost no light.
- 8 mil security window film — for medium glass surfaces. VLT 84%, TSER 20%.
- 12 mil security window film — for expansive window areas. VLT 82%, TSER 24%.
- 16 mil — for extremely large or critical security zones.
Other types of film for glass — solar, frosted, mirror — are in the protective window films section of our online store.
Installing Security Film
The method is the same as for any window film, but thick security film needs a harder, rigid-edged squeegee than a light solar film does — it will not follow the glass under a soft blade. Work the water out from the centre to the edges until no bubbles are left.
Apply the film on the side the blow would come from — that means the inside for a window reachable from the street.
Security Window Films with Self-Adhesive Properties
Every protective film for glass that we sell is self-adhesive: the adhesive layer is already on the film. You need a mounting solution and a few tools, both of which go into the order. More on this is in the self-adhesive window tint film section of our website.
What Security Film Does and Does Not Do
- It is not an absolute shield. Security film makes a forced entry slow and loud, and that is usually enough to stop it — but it is one part of the protection of a building, not a replacement for locks, shutters or an alarm.
- Resistant, not bulletproof. Contrary to some advertising claims, security films are not designed to stop bullets. The demonstrations with multi-layered film and gunfire have nothing to do with an 8 mil or 12 mil film on a house window.
Order Security Window Film Cut to Size
The 8 mil and 12 mil security window tint films are cut to your own measurements, in inches, in steps of 1/32" — one piece up to 110" on the long side. The order goes out ready to install, anywhere in the US and beyond, with the tools and the mounting concentrate included, plus a free piece of film to practise the technique on before you touch the window itself.
