Is window film insulating?

Window film can be insulating depending on the window film you select. Luckily, 3M makes insulating window films such as the 3M Insulating Series, or Low-E Window Film. These low-emissivity window films can improve the insulation of a window, providing year-round insulation and energy savings. 

3M Insulating Series

With the 3M Insulating Series, you’ll enjoy UV protection, glare reduction, and comfortable temperatures year-round from products like Low E 20 and Low E 35. Not to mention, there’s a potential payback period of just 3 years! The high heat rejection of these films keeps interiors cool in the summer, and their insulating abilities maintain comfortable indoor temperatures in the winter. In addition to its heat-rejecting and insulating properties, Low E 20 and Low E 35 also provide protection against harmful UV rays, the leading cause of fading in furnishings. This series offers impeccable glare reduction, increasing both comfort and productivity of occupants at home and in the office. The end result is enhanced occupant comfort and increased UV protection, paired with lower energy bills no matter the season.
