The world and the performance of windows has evolved a lot. The high insulating power of multi-chamber PVC and high-efficiency sealed glass (thermos) including argon gas and Low-Emission films have made it possible to make the windows solid, durable and more efficient and to minimize energy losses in the houses.

Hybrid windows combine the high insulating power of PVC and the rigidity of aluminium. Basically, Hybrid windows are windows made of 100% energy-efficient PVC and are covered with an aluminum extrusion on the outside of the window.

The NFRC (National Fenestration Rating Council) is an independent US non-profit organization that establishes objective energy performance ratings for windows, doors and skylights. NFRC products are independently tested, certified and labeled. While ENERGY STAR certification tells you if a product is energy efficient, NFRC certification helps you compare energy efficient products by breaking down a product’s energy performance. The NFRC label helps you compare energy efficient windows, doors and skylights by providing you with energy performance ratings in several categories.

The energy efficiency factor indicates the overall performance of ENERGY STAR qualified windows and doors. This performance is based on three elements. The first is the ability of a window to allow heat gain through solar radiation during the cold season. The second is to prevent heat loss through the frame, the spacer, which separates the glass plates, and the glass itself. And the last, is the ability to contain heat loss through air leakage.

The higher the RE factor, the better your doors and windows perform and allow you to save energy in your home. The method for calculating this factor is defined by the Canadian Standards Association (CSA).
