Traditional window films tend to be the most productive at reducing the heat coming through the windows, based upon their traditional reflective appearance. These films are most popular for offices where individuals are there during the day, when the sun is at its hottest and most glaring. These films can help increase the ROI on a project with a typical payback quicker than other films. While reducing 99% of the damaging UV rays, traditional series window films provides high heat reduction and glare reduction at a low cost.
Immediate incentives exist for installing window film. Most utility companies are encouraging tinting windows. In the Cincinnati area, Duke Energy is paying customers $1 / square foot of glass covered. DP&L customers are receiving payments of $2 / square foot of glass covered.
