This CRL Reflective Window Film transforms ordinary glass into high performance, transparent insulation. It eliminates up to 70% of the sun's heat and retains 55% of winter heating, without obstructing the view or natural light. It reduces glare and the UV rays responsible for fading of fabrics by 99%. During the summer months, with the heat reduction, the air conditioner will work less and in the winter it will reflect the generated heat back inside the room.
