Modular Ceiling panels bear on the walls to complete the sealed cleanroom envelope and support the suspended cleanroom ceiling system directly below. The sealed, modular, load bearing top deck is made of prefabricated structural sections spanning the width of the cleanroom. The metal lined top deck seals the cleanroom and forms an airtight negative pressure return air plenum above the cleanroom ceiling. This forms a protective negative pressure envelope to ensure leak free performance. The top deck can support the air handlers, mechanical equipment, ductwork above the structure and cleanroom ceiling below. Our standard cleanroom deck panels are constructed with welded structural C-stud on 24” centers or less and covered with one of the deck skins mentioned below. Our standard deck is designed for a 35 lb. per square foot rating.
