Visible Light Transmission iVLT (Visible Light Transmittance): The VLT (visible light transmittance) refers to the percentage of visible light that passes through the film. A high VLT allows more natural light to pass through, while a low VLT reduces glare and preserves privacy. For example, a VLT of 50% means that half of the visible light passes through the film.

VLR iVLR (Visible Light Reflection): VLR indicates the percentage of visible light reflected by the window film. A high VLR means the film reflects more light, which can enhance the building’s exterior appearance and reduce glare. However, excessive reflection may be undesirable in certain contexts.

TSER iTSER (Total Solar Energy Rejected): TSER represents the total percentage of solar energy (including heat, ultraviolet, and infrared radiation) rejected by the solar control film. A high TSER means better heat protection, helping to keep indoor spaces cooler and improving energy efficiency by reducing the load on air conditioning systems.
