A discreet solution for reinforcing existing glazing
Faced with the risk of intrusion or vandalism, reinforcing the windows of a home or business premises is a necessity, especially on the first floor or in low-traffic areas. If complete replacement with burglar-resistant glass is not an option for budgetary or technical reasons, security window film offers a simple, fast and affordable alternative.
But is this film really effective in preventing break-ins? And what protection can we expect from it? Here’s an overview of its performance, limitations and conditions of use.
What is window film?
Safety film is a transparent, multi-layer polyester film with a high-performance adhesive. It is applied directly to the inside face of existing glazing, and enables :
- reinforce the mechanical strength of the glass,
- keep splinters in place in the event of breakage,
- delay intrusion in the event of a break-in,
- improve the safety of people in the vicinity of the glazing.
Some models are certified to European standards EN 12600 (personal protection) or EN 356 (burglary resistance).
What level of protection does security film really offer?
Delayed break-in
Safety film doesn’t prevent a pane of glass from shattering, but it does prevent it from falling or shattering on first impact. So, even after a violent impact, the glass remains generally in place, making intrusion slower, noisier and therefore more risky for the intruder.
In most cases, this is enough to defeat a quick break-in attempt, especially if it relies on a sharp knock followed by immediate opening.
Variable strength depending on thickness
Security films come in a range of thicknesses (100 microns, 200 microns, 300 microns or more). The thicker they are, the greater their resistance:
- 100 microns: basic protection against splinters and accidental breakage.
- 200 to 300 microns: good resistance to attempted break-ins with simple tools.
- 375 microns and over: high level of resistance, close to that of some light laminated glass.
Models certified P2A or P3A to EN 356 are available for moderate-risk environments.
Protection against injury
By retaining shards of glass, safety film reduces the risk of serious cuts in the event of breakage, whether due to domestic accident, explosion or vandalism. This is a major advantage for shop windows, schools and public areas.
The benefits of safety film
- Quick installation without replacing the glazing,
- Lower cost than laminated double or triple glazing,
- Total discretion: once installed, the film is invisible,
- Compatible with most existing glazing,
- Solar or UV protection film can also be fitted for added thermal comfort.
Limits to be aware of
- The film doesn’t totally prevent intrusion, but rather delays and complicates access.
- It is less effective than laminated glass certified RC2 or RC3.
- Performance is highly dependent on the quality of the installation: a poorly applied film, with bubbles or without protected edges, will be much less effective.
- It does not reinforce the frame structure or the locking system, which remain potential weak points.
Professional installation guarantees efficiency
For safety film to fulfill its role, it must be :
- laid perfectly flat, without bubbles or creases,
- edged over the entire glazing surface, including corners,
- installed on clean, dry, undamaged glass.
