Had this installed on my boat. The results are mediocre at best. The heat is absorbed by the glass now albeit the surfaces inside the boat remain much cooler. However the result is the same because the glass of the window now radiates the heat. Also on my boat not all openings could be covered because many of them are acrylic and this product doesn’t do well on acrylic. This with about 40% of the openings without v-kool it really makes no difference whatsoever. I would not spend my money again on any product, instead invest in better cooling and better window treatments.

Great solar control window film selection! I will be looking into adding the V-Kool film line to my business offerings.
