TSER vs IRR: What Really Matters When Choosing Window Film?
At TMR Films, we believe in full transparency—in both film performance and how we educate our installer community.
🔍 What Is TSER?
TSER (Total Solar Energy Rejected) is the most comprehensive metric to measure heat rejection. It includes:
- UV Radiation (damages interiors)
- Visible Light (what you can see)
- Infrared Radiation (what you feel as heat)
The higher the TSER, the more total heat the film blocks.
Our CER Series achieves TSER ratings up to 95%, among the highest in the industry.
🌡️ What Is IRR?
IRR (Infrared Rejection) focuses specifically on blocking infrared radiation, which accounts for about 53% of total solar energy.
But be cautious:
- IRR can be measured across different infrared ranges (e.g., 900–1000nm vs 780–1700nm)
- Some suppliers only show partial IRR values, which can mislead
At TMR Films, we disclose both IRR metrics for full clarity.
🧠 Which One Should You Trust?
- TSER = Total heat rejection & real-world comfort
- IRR = Useful, but only when the measurement range is specified
- Avoid vague IRR claims that hide measurement details
🔧 Why Installers Need to Know This
- Educate your clients with accurate info
- Avoid overhyped film with underperforming results
- Choose the best film for each climate, vehicle, or customer need
