Low E Glass Window Film

Low e glass coatings reflect the heat back to the source allowing the short wave light to pass through for natural illumination.

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. Researchers from lawrence berkeley national laboratory found 29 average perimeter hvac savings compared to single pane clear glass. Low e glass coatings are the next step up from tinted windows and doors.

When it comes to moderating temperature in regions with seasonality low e film delivers the best of both worlds. Gila heat control platinum adhesive residential diy window film sun blocking glare reduction 3ft x 15ft 36in x 180in. 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. 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.

It also enhances insulating performance of existing windows by 44. 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 emissivity values of low e window film range depending on the film.
