CWS Comfort Window System AB is a Sweden-based company engaged in the development of windows, window frames, window glass and window closing mechanisms. The Company’s window fittings utilize a closing mechanism, which allows the window sash to be turned around by 180 or 360 degrees and locked in the opposite position. It also utilizes dual solar control glass, which complete with the closing mechanism reduces heat radiation from the outside in hot periods and heat radiation from the inside during cold periods, depending on how the window is locked in the window frame. CWS Comfort Window System AB relies on licensees to manufacture and market its products.
