Engaging Style. Efficient Design.
Thermally broken steel windows and doors provide the narrow sightlines, classic-contemporary style and superior strength of steel without the thermal conductivity issues inherent in metal.
Citadel’s NFRC-certified CWD line of windows and doors smartly integrate a thermal barrier, or thermal break, between the outdoor and indoor sections of the steel frame to prevent the cold outside from traveling to the interior.
Our CWD thermally broken steel windows and doors are available in stainless steel, RAL-painted galvanized steel, bronze or cor-ten finishes with a range of factory standard or premium hardware to accentuate the details in your luxury residential or commercial designs.
Large Thermally Broken Steel Door Systems
CWD 72 and CWD 80 allow for larger sliding windows and doors, pocketing and 360-degree corner lift-and-slide sliding steel doors with flush rail tracks or thermal breaks, accommodating panel weights up to 900 lbs or special solutions up to 144″H and 1400 lbs.
These thermally enhanced systems offer slim visible sight lines combined with cutting-edge energy efficiency for sustainable projects, with acoustic and bulletproof glass up to 2-3/8″ thick. Multiple handle and finish options are offered to achieve contemporary, modern, transitional or rustic aesthetics.
Our lift-and-slide doors are NFRC certified with U-values as low as 0.25. Available as manual or motorized, these systems enable the creation of glass walls that alternate sliding and fixed openings, allowing entire walls to be opened to the outside.
Simulated Divided Lights (SDLs) for Our Thermally Broken Lines
Citadel offers a variety of SDLs to meet the design needs of your project. SDL windows feature a single piece of glass with muntins attached to the interior and exterior with strong VBH tape. Multiple grille or muntin configurations and styles are available.
