How do I make a window safe using adhesive film for windows?

Reflective safety film is a very strong, transparent film that is applied to glass in order to reinforce it. It allows household accidents caused by shards of glass to be avoided, and slows down break-ins. This film creates a solid membrane which reinforces the glass whilst at the same time maintaining the glazing’s transparency. Reflectiv safety film complies with safety standards, and received an M1 classification from the CSTB (French Construction Scientific and Technical Centre): the polyester film is consumed without either creating or spreading flames, and even under these conditions, the film does not break into fragments.
