TORONTO - TelAve -- Demand for ceramic window tint continues to rise across North America, Tint Academy is launching a new educational initiative designed to clarify one of the most misunderstood topics in the window film industry: "98% heat rejection" claims.

For years, window tint manufacturers and installers have promoted high heat rejection numbers in advertising, often leading customers to believe that window film can eliminate nearly all heat entering a vehicle, home, or commercial building.

The Problem With "98% Heat Rejection" Advertising

According to Tint Academy, most "98% heat rejection" claims refer specifically to infrared rejection (IR), not total heat rejection.

Infrared radiation is one part of the solar energy spectrum and is responsible for much of the radiant heat felt on the skin. Premium ceramic window films are capable of blocking a very high percentage of infrared energy, often reaching 90–98% under laboratory testing conditions.

Total Solar Energy Rejected (TSER)

Tint Academy says one of the most important metrics consumers and installers should focus on is TSER, or Total Solar Energy Rejected.

TSER measures the total amount of solar energy blocked by a window film, including:

• infrared radiation
• visible light
• ultraviolet energy

Unlike standalone infrared rejection percentages, TSER provides a more realistic representation of overall heat performance.

According to the company, typical TSER performance ratings include:

• Dyed films: approximately 30–40%
• Carbon films: approximately 40–50%
• Ceramic films: approximately 50–70%

Why Ceramic Tint Still Feels Significantly Cooler

Despite the misconceptions around heat rejection percentages, Tint Academy emphasizes that ceramic window tint technology remains one of the most effective upgrades available for vehicles and buildings.

• reducing radiant heat on the skin
• lowering cabin temperature buildup
• reducing glare
• decreasing strain on air conditioning systems
• protecting interiors from UV damage

Tint Academy says one of its primary goals is helping installers communicate honestly and professionally with customers.

The organization believes that education-focused sales approaches build stronger customer relationships and improve the reputation of the industry overall.

Instead of using exaggerated claims, the company encourages installers to explain:

• how solar energy works
• the role of infrared rejection
• the importance of TSER
• realistic performance expectations

According to the academy, many new installers entering the industry rely heavily on manufacturer marketing without fully understanding the science behind the specifications.
