Serious Windows manufactures the most energy efficient window on the market today, with a full frame U Value of 0.09 (R-11)! To put that in perspective, most well insulated homes have walls with an R-13 value. Serious is able to achieve such a high U value because they insulate their fiberglass and vinyl frames with a high-density closed cell soy foam which eliminates thermal bridging through the frame, utilize a suspended film which creates additional air pockets without putting weight on the sash, a patent pending high-strength warm edge spacer system, inert krypton gases which prevent convection within the IG and Low-E sputtered coated glass which reflect heat in and out of the home. Available in super-durable fiberglass and affordable vinyl frames, each window is custom manufactured to fit your home exactly. They are available in a variety of pre-finished colors as well as natural, stainable wood interiors.
