In designing the new 28,200 sq.-ft. Mesa Rim fitness center in San Marcos, Calif., Richard & Richard Construction Co. chose Metl-Span CF Flute panels in Tundra for their thermal efficiencies and rustic look. Lending an industrial flair, the 42-in.-wide 2-in.-deep insulated metal panels integrate with a glass sectional running down one of the building corners. With its bold vertical reveals, the IMPs complement the building exterior and beacon visitors to experience the climbing wall excitement inside.
