LOW-E WINDOW FILM
Insulating Performance
Low-e window film U-value and emissivity values van range, depending on the type of film. Conventional low-e window film has an emissivity rating of 0.33, which means 67% of the room's heat is reflected back into the room in the winter. There are newer low-e window films available with emissivity ratings as low as 0.07, which means that 93% rating of the room's heat is reflected back into the space. Traditional low-e window film improves insulating performance of exciting windows by 44%; higher-performance, newer low-e window film can improve insulating performance by as much as 92% Low-e films offset the loss of free solar heat during the heating season (unlike standard window films) and normally provide both cooling and heating savings. Low-e films improve window insulating performance 24/7, while only limiting solar heat gain in winter for 2-3 hours per day on a sunny days (which are less frequent than in warmer months). The low-e coating reduces heat loss in the winter; during the summer, it reduces non-solar heat gain. ROI and Initial Cost Payback for low-e films range from 2-5 years. These film usually offer a fast ROI due to the all-season performance and typically high heat rejection properties in summer. Low-e window film can be installed in most commercial spaces. Some recently introduced high visible light transmission low-e films (70% visible transmission) are more expensive. Installation Process the same process in followed as installation process for standard window film. |
