The owner and architect were very happy with the end product. We installed them in a APC Hot Aisle Containment Pod (IT equipment rack and air conditioning unit). The stock ceiling assembly required us to drop a fire sprinkler head into the pod (which the owner wanted to avoid if at all possible ~8M in IT equipment). By using the Ceilume tile we were able to utilize the APC framing and simply added a piece of T-bar down the middle. Our fire code consultants reviewed the Ceilume tiles with the City of Napa Fire Marshall and achieved approval for their use in our installation.
