Armstrong World Industries

Together, 9F and Armstrong World Industries bring ceilings into the healthy buildings conversation.

9F identified an opportunity to shift Armstrong’s air cleaner strategy to include particles in addition to biologicals, leveraging their product to be effective at both risk mitigation from disease AND from air pollution. Armstrong released “StrataCleanIQ” 9 months later – the first supplemental air cleaner to be used in the ceiling. 9F advised on health optimization of StrataCleanIQ through noise and placement considerations.
