The ceiling of the baggage area at Terminal C needed a two hour rating. Based on UL Design D303, we were able to provide the proper rating using Albi DriClad. With no concrete or insulation over the metal deck, Albi recommended attaching 1-5/8 inch DriClad directly to the corrugated roof deck using self-tapping screws with one inch washers. The screws and washers were installed one foot on center.
In addition, Albi DriClad provides noise dampening and an R-Value of 4.1 per inch.
