Window Films for Safety and Security: Protecting What Matters Most Copy

The Composition of Security Films

Security window films are engineered to reinforce glass, making it more resistant to impact and less likely to shatter. These films are typically made from multiple layers of high-strength polyester, bonded together with powerful adhesives. The thickness of security films—measured in mils (1 mil = 0.001 inches)—ranges from 4 mils for basic protection to 14 mils or more for maximum security. The thicker the film, the stronger the barrier.

When applied to glass, security films create a “safety net” that holds shattered pieces together, even if the glass breaks. This prevents dangerous shards from scattering, reducing the risk of injury and making forced entry more difficult.

Installation: A Precision Process

Proper installation is crucial for security films to perform effectively. At Window Film Installers, our expert technicians ensure that the film is applied seamlessly, without bubbles or wrinkles that could compromise its strength. The process involves:

• Cleaning the Glass: Removing dirt and debris to ensure a smooth application.
• Applying the Film: Carefully positioning the film and using specialized tools to eliminate air pockets.
• Securing the Edges: Using anchoring systems or sealants to enhance the film’s hold, especially for high-risk areas.

This meticulous approach guarantees that your security film provides maximum protection.

Types of Security Films

Not all security films are created equal. Depending on your needs, you can choose from:

• Clear Security Films: Invisible protection that maintains the glass’s original appearance.
• Tinted Security Films: Combine security with solar control, reducing heat and glare.
• Decorative Security Films: Add privacy or branding while reinforcing the glass.

Each type offers unique benefits, and our team can help you select the best option for your property.

films boost energy efficiency, we need to start with the sun. Solar energy reaches your windows in three forms:

• Ultraviolet (UV) Rays: Harmful rays that fade interiors and pose health risks.
• Visible Light: The light you see, which brightens your space.
• Infrared (IR) Radiation: The heat you feel, responsible for warming up your rooms.

Window films are designed to manage these elements, particularly IR radiation, to keep your space cooler and reduce the strain on your HVAC system.

Heat Rejection Technologies

Window films use advanced materials to control heat in two main ways:

• Reflective Films: These contain metallic layers (like aluminum or silver) that bounce IR radiation back outside. They’re highly effective but can have a shiny appearance.
• Absorptive Films: Often made with nano-ceramic particles, these films soak up IR radiation and dissipate it, offering excellent heat rejection without a mirror-like finish.

Both types reduce the amount of heat entering your space, but the choice depends on your aesthetic preferences and performance needs.

Metrics That Matter

When evaluating energy efficiency, two key metrics stand out:

• Total Solar Energy Rejected (TSER): This percentage shows how much solar energy (UV, visible light, and IR) the film blocks. A film with a TSER of 70% rejects 70% of solar energy, keeping your space cooler.
• Solar Heat Gain Coefficient (SHGC): This measures how much solar heat passes through the window. Lower SHGC values (e.g., 0.3 vs. 0.7 for untreated glass) mean less heat gain and better efficiency.

At Window Film Installers, we select films with optimal TSER and SHGC ratings to maximize energy savings for our clients.
