The main types of commercial window film are: solar control / sun control film (reduces heat and glare, best for energy savings), security film (thicker film that holds glass together on impact — ideal for storefronts, retail, and ground-floor office glass), privacy / decorative film (frosted, etched, or patterned options for glass partitions and conference rooms), low-E film (improves insulation performance of existing glass year-round), and anti-graffiti film (sacrificial exterior film for high-traffic areas). We carry the full LLumar commercial film lineup and will recommend the right product for your specific needs.
