The CSW4 range combines all of the best features of the CSW3 with 'timber style' joints to the main frame and sashes, and a slim mid-rail. The inclusion of 18mm Krypton gas filled double glazed units allows deeper internal Georgian bars, which, combined with the timber joints and mid-rail, creates a truly authentic sash look.

Please take time to browse the gallery of images and detailed CSW4 product specification that appears below.
