A window assembly having heat insulative properties with an R value of at least about 3 characterized by being transmissive to incident light, said window assembly comprising a window, and an insulator extending along and covering one side of said window, said insulator comprising a high loft body of bonded together synthetic fibers and a sheet of plastic positioned to extend along and cover one side of said body of fibers, said high loft body having a thickness many times that of said sheet of plastic, and said insulator being positioned on said window so that the body of fibers is sandwiched between the window and said sheet of plastic.
