The airfloor system allows for incorporation of a raised floor system, with a lower cost than a traditional pedestal type raised floor. The system consists of sheet metal forms installed over a structural slab and then covered with a topping slab with a finish material as desired by the design team. The system requires 5" depth. Linear diffusers are cast directly into the topping slab. The airfloor allows the floor system to also function as a radiant slab for heating and cooling. Application of this technology requires close coordination with the vendor, structural, mechanical, and architectural disciplines.
