We installed VISTA Ultima V-14 on 3 windows that face the South Western Sun. It was very hot inside while we were installing film. With the sun beating in the 3 windows a lot of heat was generated and their air conditioner could not keep up to cool the area. When the film was installed the difference was dramatic. You could actually feel the air conditioning.
The VISTA Ultima V-14 rejects 80% of the Total Solar Energy.
This film will block 99.9% of the Ultraviolet light.
It will keep in heat in the winter and provide daytime privacy.
