Just imagine how working close to windows in the summer can cause discomfort and drowsiness due to the solar heat, and how this can lead to mistakes. Glasstint solar control window films can deflect up to 80% of the sun's heat and reduce glare without shutting out the view and daylight. Air conditioning costs can be reduced and staff performance and comfort increased. The film which keeps you cool in the summer can  also help retain the warmth in winter.
