Buyer-focused explanation
VLT shows how much visible light passes through the film. UVR shows UV protection. TSER expresses total solar energy rejection and is useful for understanding overall heat control. IR rejection is important for heat comfort but should be read together with TSER, product structure and glass application. A professional buyer should not select a window film by one number alone.
