Yes, proper anchoring is a critical final component for effectively using security window film. Many people mistakenly believe that applying film to the glass surface is sufficient on its own, but film without a secure attachment to the frame provides limited resistance. Without proper anchoring, an intruder could tear the film from the edges and push the entire filmed sheet out of the frame as a single unit.
To prevent this, a high-strength structural silicone anchor, such as Dow Corning 995, is used to bond the perimeter of the filmed glass directly to the frame. This ensures that impact energy is transferred from the glass through the film and into the surrounding structure. For modern buildings with unframed or butt-glazed glass systems, specialized perimeter attachment methods are used. A professional security assessment is required to determine which specific windows and doors necessitate anchoring based on accessibility, sight lines, and local response times.
