Low E Glass Window Film

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.

Low e glass window film.

The coating is applied to the internal glass to separate both heat and light energy. It also enhances insulating performance of existing windows by 44. 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. When it comes to moderating temperature in regions with seasonality low e film delivers the best of both worlds.

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. Researchers from lawrence berkeley national laboratory found 29 average perimeter hvac savings compared to single pane clear glass. Conventional low e window film has an emissivity rating of 0 33 which means that 67 of the room s heat is reflected back into the room in the winter. Low e glass coatings are the next step up from tinted windows and doors.

Low e window film emissivity values of low e window film range depending on the film. Low e window film u value and emissivity values can range depending on the type of 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.
