Flexible Design. Rigid Strength. Ultimate Performance.
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.

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.
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.
Mullion/Transom | 1-15/16" Deep
Mullion/Transom | 3-15/16" Deep
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/Skylights | Sloped and Roof Glazing Systems
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.
