Film thickness is a primary driver of the cost per square foot because heavier gauge films require more raw material, more sophisticated manufacturing processes (such as multi-layer lamination), and specialized handling during installation.
As the thickness of the film increases, both material and installation costs rise accordingly:
- 4–6 mil (Standard): These entry-level films are the most affordable, typically costing $4–$6 per sq. ft. for materials and $3–$5 per sq. ft. for installation. They are primarily used for basic shatter control and glass fragment retention.
- 7–8 mil (Mid-Range): These films provide moderate forced entry delay. Material costs range from $6–$9 per sq. ft., with installation costs between $4–$7 per sq. ft.
- 12–14 mil (High-Security): These thick, multi-layer films are designed for significant forced entry delay and blast mitigation. Materials cost between $12–$15 per sq. ft., and installation labor rises to $7–$10 per sq. ft.
Beyond raw materials, thicker films (particularly 14 mil) are stiffer and heavier, often requiring wet-glaze attachment systems to bond the film to the window frame. These specialized anchoring systems add further material and labor expenses, typically increasing the total project investment to ensure the film performs under extreme stress.
