With clear glass comes incredible solar heat gain. Even an eastern exposure will build heat quickly on a sunny day. Window tinting can block over half of the heat gain without over darkening the windows. This commercial property had about 1000 sq/ft of glass and we completed the installation in three short 4 hour sessions without interrupting anything. All of our products come with either a 15 or 16 year warranty for commercial applications. Call Naples Tint Company today and learn more about our energy efficient window films. 239-571-9551
