Coavas Privacy Window Film, 29.5 x 78.7 Inches, Frosted, UV Blocking, Non-Adhesive, Static Cling

Quizá no leí bien pero el material absorbe todo el calor del sol, no detiene la temperatura en un cuarto de 3x3 al contrario se siente más el calor. Es un muy buen producto solo no fue para mí.

Installation was conceptually easy. For larger windows it helped a lot to have a second person. The end result looks very nice. The marketing claims that it reduces 90% of UV light. That sounded way too good to be true. So, I measured it myself. I found a 36% reduction, at least in the 405 nm +/- 3% range. This range is important for those working with UV-curing resins.

La calidad del material es muy buena, hay que revisar bien las instrucciones de instalación es fácil, solo hay que cubrir todo muy bien con agua para que pueda pegar. No se transparenta en lo absoluto. Totalmente negro

Están un poco pequeña de tamaño, se requiere más de uno pero funciona bien al tapar la luz

First I think it's important to mention this in fact does help with cooling and UV reflection. Using an infrared thermometer around the treated window and an untreated window there are significant differences in internal temperature of the house, approximately 15 degrees difference. That is substantial enough to say it's worth it. My issues are cosmetic mostly, this stuff is thick, hard to work with and the worst part for me scratches. Even using a squeegee I have scratches all through the new tint due to installation. I soaped up the area before squeegeeing and it still left scratches. That alone is extremely frustrating, I will have to reorder another roll, because one roll did 1.5 windows, so that was a little unfortunate an extra 8 inches on a roll would have allowed for two whole decent size windows (36x61). For continuity I will get another roll to finish out my upstairs but I will likely not order this for my other windows downstairs. The exterior is very silver, again cosmetic, not a huge fan, but the temperature difference alone lets me overlook that. I would give this overall 3.5 stars due to the scratching but the effectiveness of UV transmission or lack thereof is worth it.
