W-20 SWISS STEEL
The W20 windows and doors range offers great versatility. No other steel window system offers such an extensive range of sections, allowing the designer the opportunity to create many styles including elaborate composite windows.
An effective weather-stripping system, and the option of double glazing up to .55 inches when gasket glazed, and .63 inches wet glazed ensures excellent thermal insulation properties, while the system’s large opening casements and slim frame make it particularly popular with conservationists and planners.
