Low E Glass Window Film

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

Low e glass window film.

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

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 a room s near infrared heat is reflected back into the building in the winter.
