Low E Glass Window Film

It also enhances insulating performance of existing windows by 44.

Low e glass window film.

The coating is applied to the internal glass to separate both heat and light energy. 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 glass coatings reflect the heat back to the source allowing the short wave light to pass through for natural illumination.

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 emissivity values of low e window film range depending on the 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. 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.

Researchers from lawrence berkeley national laboratory found 29 average perimeter hvac savings compared to single pane clear glass. 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. Low e window film u value and emissivity values can range depending on the type of film.
