The Corporate W20 window and door range offers great versatility in size and shape. No other steel window system offers such an extensive range of profiles, allowing the designer the opportunity to create many styles including elaborate coupled assemblies.
An effective weather stripping system and the option of double glazing up to 16.4mm / 5/8″, ensures excellent thermal insulation properties – and the system’s large opening casements and slim frame make it particularly popular with conservationists and planners.
