The extra large floor to ceiling tiles really put our skills and experience to the test. Each slab was 8 feet tall x 3 feet wide and at only ¾ inches wide, they were extremely fragile. It took 2 mechanics to hold one slab and our installers had to use extreme care while installing them, with suction cups. It took a lot of planning and meticulous preparation to protect the new apartment floors, walls, and the furniture.
