Wooden windows offer the highest level of aesthetics on buildings. It can match the architectural style of any building. With low maintenance they always look like being brand new. With the painting process adopted by BG Legno, the maintenance level is extremely low, and life expectancy of a wooden window is the same of that of the building where it is installed, contrary to a PVC window, which cannot guarantee a long durability. With minimal care and some hints, a wooden window can last a very long time, and preserve its beauty.
