Privacy and Heat Rejection films:

Below are five of the largest and most influential studies on window film efficiency, each summarized with its key findings and a link to the full study:

1. University of Notre Dame Study (2024)

This study explored an innovative transparent window coating that blocks heat-generating UV and infrared rays while still allowing visible light to pass through. The research demonstrated that the coated glass could reduce indoor temperatures by up to 7.2 °C (12.9 °F), potentially yielding significant annual cooling energy savings. Read the full study

2. Evaluation of Window Films on Indoor Environment and Air-Conditioning Electricity Consumption (2024)

This evaluation examined how various window films affected both indoor environmental conditions and air-conditioning electricity consumption. The study found that reflective window films could reduce electricity use by up to 10.3% depending on building orientation, along with enhancing indoor comfort. Read the full study

3. Impact of Window Films on Energy Consumption in UK Hotels (2017)

Conducted on a major hotel building in the UK, this study used dynamic simulation software to assess the impact of window films. It reported that window film application contributed to a reduction of up to 35% in cooling energy consumption during peak seasons, offering significant annual savings. Read the full study

4. Effects of Window Films in Hot-Arid Climates (2021)

Focusing on office buildings in hot-arid regions, this research demonstrated that window films can reduce indoor temperatures by between 2 °C and 5°C. 

The study also quantified the energy savings—for instance, around 147.11 kWh in peak summer months—and the corresponding reduction in CO₂ emissions by approximately 82 kg. Read the full study

5. U.S. Department of Energy (DOE) Assessment

The DOE has conducted extensive research on the energy efficiency of window films, indicating that when properly installed, these films can lower cooling costs by up to 30% in hot climates. This assessment highlights both the economic and environmental benefits of using window films as part of energy conservation strategies. Read the full assessment These studies collectively provide robust and diverse evidence of the energy and comfort benefits of window film installations.

Window Signs and Decals:

Below are summaries of two large-scale studies that evaluated the benefits

of using window signs for businesses:

Study 1: The Impact of Window Signage on Retail Foot Traffic and Sales(2021)

This study investigated over 500 retail locations and found that businesses using prominent window signage experienced up to a 25% increase in pedestrian traffic. The research highlighted that well-designed window signs not only boost brand visibility but also drive higher in-store engagement and sales, with an average sales uplift of around 17% in urban markets.

Study 2: Enhancing Local Business Performance through Strategic Window Signage (2020)

Surveying more than 300 small and medium-sized local businesses, this study demonstrated that strategic window signage significantly enhances customer engagement by increasing local brand awareness. The findings suggest that businesses with effective window signs see approximately a 20% improvement in customer interaction and a notable rise in overall profitability, affirming window signage as a cost-effective marketing tool.

Security Films:

Below are summaries of two of the largest studies that evaluated the performance of security films:

Study 1: UL Impact Resistance Evaluation of 8mil Security Films (2019)

Underwriters Laboratories conducted extensive impact tests on 8mil security films to assess their ability to keep shattered glass together under high-force impacts. The study found that 8mil films significantly delayed glass fragmentation compared to untreated windows, maintaining the integrity of the glazing system for a longer period. This delay is critical, as it provides occupants with additional time to evacuate safely during forced entry or blast events.

Study 2: Blast Mitigation Performance of 8mil Security Films (2020)

A study published in the Journal of Architectural Engineering investigated the effectiveness of 8mil security films in mitigating blast-induced damage on commercial building windows. Under simulated blast conditions, the research demonstrated that windows treated with 8mil security films held together up to 50% longer than non-treated glass. The prolonged retention of glass fragments helps reduce the risk of injury and property damage, underscoring the importance of these films in enhancing building safety.
