We manufacture both flush joinery casement windows and stormproof windows. The flush joinery window is a more traditional style that you would almost most certainly be required to use in listed buildings. The opening sash itself sits within the outer frame, hence the term flush. The stormproof window envelops the outer frame and is probably better suited in more exposed areas. In most cases, it is mainly a matter of personal preference and aesthetics. There are examples of both styles in our gallery section.
