U S Block Windows is the only source for the luxurious, lightweight features of acrylic block in single hung or slider form. These operable windows provide ventilation and are an ideal complement in the bath, bedroom, or any room where privacy and light are desired.
Acrylic block size is 6″ x 3/4″. The narrow profile of the 3/4″ thick block enables the operating sashes to ‘slide’ by one another – a major innovation for acrylic block windows.
Our single hungs or sliders come in several standard sizes in vinyl. Special sizes and radius tops are also available.
