We fitted 35% silver film for privacy on all the front facing downstairs windows of this home. 35% silver blocks 35% of visible light, so is more subtle than the more common 20% silver film. We usually recommend this more subtle film for home windows like this for aesthetic reasons. The film was fitted for privacy – an attractive alternative to net curtains. As a bonus, our film prevents the fading of carpets, upholstery, etc, as it blocks 99.9% UV. It also blocks around 65% of the sun’s heat.
