Low e window film emissivity values of low e window film range depending on the film. Low e window film low e film blocks direct solar heat to reduce summer cooling demand and insulates to reduce summer and winter energy use and improve occupant comfort. It also enhances insulating performance of existing windows by 44.

The coating is applied to the internal glass to separate both heat and light energy. Both a window insulation film and heat block window film low e films are designed to retain cool air during the summer and heat during the winter so you can save on energy costs all year round. Conventional low e window film has an emissivity rating of 0 33 which means that 67 of a room s near infrared heat is reflected back into the building in the winter. Researchers from lawrence berkeley national laboratory found 29 average perimeter hvac savings compared to single pane clear glass.

There are newer low e window films available with emissivity ratings as low as 0 07 which means that 93 percent of the room s heat is reflected back into the space. Low e window film u value and emissivity values can range depending on the type of film. And when you choose 3m low e window film you can leverage advanced window insulation performance much like upgrading to a double pane or triple pane window to help lock in heat.
