External silver reflective mirror window film has been developed for exterior use where internal access is difficult. This is particularly useful when applying the film to tinted and patterned glass and especially roof lights. Once fitted, the film offers high heat refection by blocking and reflecting solar energy before it penetrates the glazing. In turn, this can lead to improved living & working conditions and a reduction in air conditioning costs. It can also alleviate the discomfort of glaring reflections from computer screens, and assist in compliance of the workplace regulations. This high performance solar reflective one-way mirror film, gives a uniform reflective appearance to the glazing from the outside, whilst from the inside it is much less noticeable and maintains the transparency and visual properties of the glazing.
