Frequently Asked Questions

Yes! Security films add shock absorption, reducing breakage risks in homes, schools, and public buildings.

  • Deter intruders by delaying forced entry.
  • Reduce injury risks from broken glass.
  • Improve safety in high-risk zones like front entrances & classrooms.
  • Mechanical Anchors: Metal clamps securing the film to the window frame.
  • Wet Glaze Adhesives: Thick, flexible silicone sealants that bond the film to the frame for blast resistance.
  • 4-6 mil: Basic impact protection
  • 8-12 mil: Strong protection against forced entry and extreme weather
  • 15+ mil: High-security applications (blast resistance, anti-theft, riot protection)

Yes! Dual-purpose security + solar films:

  • Reduce heat loss in winter
  • Block infrared heat in summer
  • Use ammonia-free cleaners
  • Avoid sharp objects or abrasive scrubbing
  • Use microfiber cloths for best results

Yes, some films meet UL 10B fire standards, slowing down flame spread and preventing glass from exploding under heat.

Unlike standard solar or privacy films, security films are thicker (4-15 mils) and designed to absorb impact energy, preventing glass from shattering on impact.

Yes, multi-layer security films help protect storefronts from looting, vandalism, and forced entry.

No, but some films have scratch-resistant coatings that prevent minor damage.

Security films disperse blast pressure across the film’s surface, reducing shockwave penetration and keeping shattered glass in place.

Yes, but they must be thermally safe films to prevent glass stress and breakage.

Yes, GSA-rated blast-resistant security films absorb shockwaves and reduce flying glass debris, minimizing injuries.

In ASTM F1642 & GSA testing, properly installed films reduce glass fragmentation by up to 92%, minimizing casualties in bomb explosions.

Yes! Anti-graffiti films provide a sacrificial layer that can be peeled off and replaced after spray paint or acid etching attacks.
