Wood/Aluminum Clad Windows and Doors
When it comes to the fit and finishes of windows and doors this is the obvious choice. There are literally dozens of combinations of wood types and finishes available. The additional cost of these windows is made up for in beauty, style and craftsmanship. These can be used as picture windows, casement, French and sliding doors, as well as custom shapes are available.

This option is an excellent choice to get the best of both worlds in both wood and vinyl windows. These windows have the durability of vinyl and can handle extreme heat and cold with little to no maintenance.
