Increase Comfort & Promote Energy Efficiency
Window film is a simple, cost effective way to achieve two important goals in the building environment:
Reduce or eliminate occupant discomfort due to temperature imbalances
Decrease building operating costs by reducing consumption of fossil fuels
Window film products are engineered to reduce solar energy transmission, absorbing and reflecting portions of solar energy to control excessive heat gain and glare. The evolution of metallic and ceramic deposition technologies in recent years has enabled durable film products with a range of performance and appearance characteristics.
A Balance of Temperature Control & Natural Light
One aesthetic concern is that greater solar control performance has required heavier coatings. This means that a noticeable decrease of heat gain may result in substantially reduced visible light transmission. In response to this problem, 3M developed the “amber” metallization technology that enables products to manage the solar spectrum selectively. Amber coatings reject more of the longer, heat producing, infrared wavelengths than the shorter wavelengths that are visible to us, preserving the positive effects of natural daylight while significantly reducing cooling loads. These characteristics are particularly useful in applications on windows with existing tinted glass that tend to block more visible light than heat.
Save Money with Reduced Energy Costs
This technology has been used extensively for solar control applications in office space in the Pittsburgh area for projects such as the Frick Building, the Pittsburgh Hilton, Building Six at Gateway Center, several PPG facilities, and the Foster Plaza complex in Greentree. Building managers in the Pittsburgh area have reported that this efficiency provides payback through reduced utility consumption expense in one to four years. In our climate, particularly considering current trends in utility costs, heating consumption cost savings can equal or surpass the savings realized in the cooling season.
Inclusion of reductions in demand charges and HVAC maintenance expense can cut these payback periods in half. Some buildings have avoided expensive capital expenditures entirely when the resulting reduction in cooling load means that the existing HVAC systems can be balanced to satisfy the needs of building occupants. Many times the project is largely justified by the value of increased tenant satisfaction and occupant productivity in the affected areas and the enhancement of the exterior appearance of the property.
Temperature Control Window Film on Low-E Glass
Windows that come with tint or a “low-e” coating provide a very mild form of protection similar to that of window film. The addition of a window film will substantially increase the performance of any treated glass. Pittsburgh Window Film assists you in determining the characteristics of your existing glass and how much additional protection the film will provide.
