    The energy efficiency of our windows is as a result of the patented 5 chamber profile used in our window frames. This structure, compared to our competitors 3 chamber profiles, helps to maintain a significantly improved thermal profile, allowing for much higher energy efficiency.

    • A 70mm profile depth
    • Internal beading that provides higher security
