How Thick Should Burglar Window Film Be?
-
Consider Your Needs
-
Security window film tends to range from 4 mil to 15 mil. The measurement refers to the thickness of the layer of plastic, polyester or other material that makes up the film. Higher counts, such as 15 mil, are usually intended to protect against disasters as severe as bomb blasts and floods. For a homeowner concerned primarily with personal security, it is not necessary to go any thicker than 6 mil.
Consider Costs
-
Six-mil window film costs 20 percent to 50 percent more per square foot than 4 mil, but it also offers superior UV ray protection. If you have sensitive documents or possessions that could be damaged by the sun, this added protection might be beneficial. Both 4 mil and 6 mil can have additional anti-vandalism properties for a slight increase in cost. These additions make it easy to wipe off spray paint and other kinds of graffiti.

Bottom Line
-
For homeowners looking to enhance the safety of their property with window film, the most cost-effective choice is 4 mil or 6 mil. Either will keep the property secure from most burglary attempts.
