Obscure glazing

One of the remarkable aspects of the sash windows manufactured by Coluxor is their faithful resemblance to the windows of the Victorian and Georgian eras. From an external perspective, they retain the classic charm and elegance of those bygone times. However, it is important to note that advancements have been made in terms of performance, thermal efficiency, glass units, timber treatments, and security standards. These improvements have been implemented to meet evolving needs and legal requirements, although they may not be immediately apparent. Interestingly, despite these concealed enhancements, the timeless appearance of the traditional sash window remains unchanged. This ingenious design allows for overall improvements to be made without altering its essential character in the slightest.
