Sash windows are thermally efficient and environmentally-friendly units which mimic the aesthetic appeal of a classic timber box sash window, but deliver all the benefits of a modern PVC-U system.
PVC-U vertical sliding sash windows are manufactured to exact customer requirements in unit sizes from a minimum 370mm in width and 740mm in height, up to a maximum of 1600mm in width and 3000mm in height.
Shaped windows are also available in Swept Head, Gothic Arch and True Arch architectural styles. These impressive windows employ specially curved PVC-U profiles and are supplied with a fixed top sash and sliding bottom sash to provide ventilation.
Subject to dimensional design limitations, Swept Head windows can sometimes be manufactured with a shallow-sliding top sash in addition to a sliding bottom sash.
