  1. This is really interesting that wood cladding windows are being developed using modern materials and techniques. How much longer are these windows likely to last for with this aluminium exterior cladding compared to conventional wooden ones?

    The exterior cladding has a longer warranty than the windows. It protects your investment from rain, wind and debris for much longer. It’s really the reduction in maintenance that makes cladding a cost saver. With cladding, there’s less of a need for painting, scraping and etc on the outside of your house.
