What is TSER?
Short Answer
TSER stands for Total Solar Energy Rejected. It measures the percentage of total solar energy (UV, visible light, and infrared) that a film blocks. Higher TSER means more overall solar energy rejected.
Full Explanation
TSER is one of the most useful metrics for comparing window films because it accounts for all three components of solar energy: UV radiation, visible light, and infrared radiation. A film with 65% TSER blocks 65% of all incoming solar energy. This is more comprehensive than looking at IR rejection or UV rejection alone. When comparing films, TSER gives a holistic view of thermal performance.
What to Consider
- TSER accounts for UV, visible light, and infrared together
- Higher TSER = more total solar energy blocked
- Compare TSER when evaluating different film options
- TSER is different from VLT (darkness) — a light film can have high TSER
- Ceramic films often achieve the highest TSER ratings
