V-KOOL is a pioneer in window films technology in Malaysia. The ‘V’ in V-KOOL is derived from the spectral-selectivity properties characterized by the films’ coating. In a wavelength vs. rejection graph, V-KOOL lets most of the visible light through, but rejects almost all the infra-red and ultra-violet wavelengths. This appears as a V-shaped graph, thereby representing the ‘V’ in V-KOOL. Cool, right?
