Engineers have now found that when reducing 79% of solar heat gain coming through 100 sq ft of glass space will reduce 1 ton of cool air. Many of the window films qualify in this category. This again proves that window film is a fantastic solution to reducing heat gain in buildings as long as the right products are installed.

This information was gathered through a LEED certified Gold building in California.

Solar screens do not qualify in any way close to this. This just proves that solar screens are very poor for removing heat loads at all times of the day.

This study makes me smile!
