Curtain wall defines the look and performance of a modern building. CBE Glass installs and repairs stick-built curtain wall, window wall and storefront-to-curtain-wall transitions for offices, schools, healthcare facilities, grocery anchors and mixed-use developments throughout the Washington DC metropolitan area.

Working with general contractors
We work as glazing subcontractor for general contractors on new construction and renovation projects. Our team reviews shop drawings, coordinates openings and anchors, and installs with lifts and cranes on active job sites, as seen on projects like the Weis Markets building in Waldorf, CC Prep School and the INOVA medical office building.
Repair and maintenance
Leaks, fogged insulated units and failed sealant reduce comfort and damage interiors. We diagnose curtain wall problems, replace failed IGUs and restore weather seals to extend the life of your building envelope.

What is the difference between curtain wall and storefront?
Storefront is typically used at ground level and spans floor to floor, while curtain wall is a non-structural exterior wall that can span multiple floors and handle higher wind and water loads.
Do you repair existing curtain wall?
Yes. We replace broken or fogged glass, re-seal joints and fix water infiltration on existing curtain wall systems.
