Albuquerque Public Schools (APS) in New Mexico have been undertaking a massive classroom and educational rebuild and remodel. All new construction has been designed using sustainable materials and energy-efficient principles with LEED certification as the end goal.
As part of new buildings under construction is a 108,000 sq. ft. central Food and Nutrition Services Kitchen and Storage Warehouse.
Originally specified XPS was replaced with Insulfoam R-Tech VI 40 psi over the sub slab freezer floor. The project utilized 2 lifts of 3″ R-Tech instead of 3 lifts of 2″ XPS ultimately saving the concrete contractor approximately $20,000 in material costs.
