Security
film holds shattered glass together. This prevents injury
from flying glass shards and prevents contamination from
falling pieces of glass.
Some
grades of film will prevent puncturing from
objects up to
230 lbs!
Because
security film prevents glass from separating, the
glass won't let go — any "smash & grab" thieves
won't get in easily.
Some
insurance companies offer a rate reduction when your windows
are protected.
