Flexible Design. Rigid Strength.
Citadel’s diverse line of thermally broken profiles for steel-frame facades, curtain walls, sloped glazing, large rooflights, and integrated window and door systems offer unprecedented design freedom combined with the superior strength of steel.
Designers can develop glass curtain walls and sloped glazing with minimal sightlines and choose from numerous capping profiles, all while employing steel’s durability and structural support.
Steel-Frame Facade and Curtain Wall Systems
Our selection of integrated steel-frame facade and curtain wall systems enable larger spans of unobstructed glass than aluminum alternatives while maintaining narrow sightlines of 1-15/16″ to 2-3/8″. A range of depths is also available to suit aesthetic considerations or specification needs.

CWD F1 Glazing System
While all of our glazing systems are available in galvanized or stainless steel profiles with a variety of finishes, designers can opt for cor-ten profiles or brass mullion covers with Citadel’s CWD F1 system.
Versatile and Energy Efficient
The CWD F1 steel curtain wall and facade system offers a highly adaptable design while maintaining outstanding energy efficiency, providing a low U-value of 0.14.
To accommodate the larger structural sections required to support extensive glass surfaces, the mullion and transom sections of the CWD F1 feature a width of 1-15/16″ and depths from 1-15/16″ to 7-1/16″.
The 2-3/16″ (56 mm) glazing panel is installed frontally and placed on glass supports that are secured to the structural profiles and fixed to the mullions and transoms through a external steel cover pre-drilled for screws.
For a refined final design, the CWD F1 steel facade and curtain wall system incorporates fully concealed ending caps that join the heads of the mullions and transoms in seamless configurations.
Steel Large-Span Rooflights
Large rooflights can drastically increase the natural light of an interior, thereby improving energy efficiency by reducing reliance on electric lighting. This infusion of softer light can also be enjoyed without the loss of privacy in intimate spaces like living rooms, bedrooms or bathrooms.
Every Citadel large-span steel rooflight is individually manufactured and made to order, giving architects and designers complete freedom. For added sun protection, an optional self-cleaning glass is available in low-iron clear or one of several colors.

Sloped and Roof Glazing Systems
Citadel’s sloped and roof glazing systems do not require external pressure plates or capping profiles, allowing designers to maintain an open glass look with much larger or multi-faceted areas of structural glazing than other systems.
Our sloped glazing systems can be constructed quickly and efficiently, with the glass panels structurally bonded to the aluminum retaining profiles with silicone. The profiles are secured to the grid by concealed stainless steel retaining clips before being reinforced with backing rods and structural silicone between the glass.
The end result is a sleek, minimalist four-sided glass wall with no visible signs of mechanical retention and no need for additional structural steel support.
