The CWS-75 Slim window and door system is an updated version of our original 65 deep system. The additional depth allows us to offer a higher level of thermal insulation and a wider range of opening configurations, all with the same ultra-slim steel framing design.
With a two-part thermal break in the slightly deeper system, you can achieve enhanced thermal performance from a slim framed steel window and door system as well as an improved weather resistance and durability.
Along with the improved performance is an increased maximum height and a broader range of opening types that are available, including a modern tilt and turn window option.
The steel framing is still slim, offering a thermally efficient alternative to traditional steel window and door systems. As with all of our CWS range the cold rolled steel profiles are available in traditional galvanised steel, stainless steel, Corten steel and architectural bronze and all installations have the option of a bespoke glazing bar design.
