So why choose us as your curtain wall supplier?

We are an unquestioned leader at pushing the limits of traditional curtain wall systems. And while our custom capabilities are extensive, we offer a full range of standard curtain wall products, including industry leading thermal products like our RelianceTM HTC, which meets the most stringent thermal performance demands. Add hurricane and blast-resistant models to our product profile and you have the most comprehensive curtain wall offering available anywhere.
Reliance™ Products: Reliance™ products offer a multitude of performance and design options. Varied system depths and internal nesting steel reinforcement allow tailoring of the curtain wall system to job-specific performance requirements for applications ranging from self-supported high-span lobby entries to entire building skins.

We have custom-engineered curtain walls for some of the world’s leading architects on landmark projects including Great American Tower at Queen City—HOK, Three PNC Plaza—Gensler, 1000 Connecticut Avenue—Pei Cobb Freed & Partners and many others.
Architectural Glass: Oldcastle BuildingEnvelope® can provide a fully-glazed system from one source. We are the only curtain wall manufacturer that can design, manufacture, manage and deliver custom-engineered curtain walls with fully-integrated architectural glass all from one source.
