Armstrongs Prelude Plus XL FireGuard Cross Tee is engineered to perform in demanding environments, including areas subject to occasional moisture exposure or cleaning agents. With a recycled content of approximately 30 % and compatibility with Armstrongs Sustain portfolio, it supports sustainability goals without sacrificing strength. The torsion-stitch construction enhances rigidity and sag resistance, enabling clean, flat ceiling planes over large spans. When paired with FireGuard-rated panels and main beams, it contributes to a code-compliant ceiling system with robust durability and installation efficiency.
