Meet the new standard in thermal window walls. TCR-225 combines seamless design with unsurpassed efficiency, weathering tough environments, installing with ease and saving you on glass costs, to keep you on budget. At Oldcastle BuildingEnvelope, we’re redefining every detail of thermal performance and aesthetics from the ground up.

TCR-225 is available dry-glazed and as a pre-glazed system, significantly reducing field labor costs and making installation easier, allowing you to stay on schedule and on budget.

Our proprietary triple hollow thermal strut provides exceptional thermal performance to achieve industry-leading U-Factors without triple glazing. An innovative front screw spline provides tight, more consistent joints, eliminating visual gaps between horizontal and vertical mullions for a flawless window wall. Dual finish options allow for customized aesthetics.
