Box Window
Box windows are one of the models manufactured by our company, created to preserve the architectural heritage and traditions of past eras. They are handcrafted by qualified craftsmen with the utmost care and attention to stylised details. They combine modern technology, excellent insulation performance, and a traditional historical appearance. Their construction consists of a window frame made up of an outer frame and an inner frame, to which double inward-opening window sashes are fitted. The outer sashes always have slightly smaller dimensions than the inner sashes, allowing both sets to be opened freely and simultaneously. These windows are used in buildings under strict heritage conservation protection, including historic townhouses, castles, and traditional rural houses.
