A: Concrete is very porous and a significant source of particulates. Common cleanroom flooring choices to eliminate this contamination and provide an easy to clean surface are heat weld vinyl, epoxy and industrial VCT tiles.
A: Heat welded vinyl cleanroom floors are easy to clean, give good chemical resistance and have good no slip characteristics.
A: The heat welded vinyl flooring is installed 4” up the cleanroom wall. This is called coving. It provides the cleanroom wall protection from the strong chemicals and floor cleaning solutions often used in pharmaceutical and medical device manufacturing cleanrooms.
A: Epoxy cleanroom flooring is seamless and easy to maintain. Combined with an additional urethane layer, an epoxy cleanroom flooring can give good chemical resistance. Epoxy cleanroom flooring can be lower cost than heat welded vinyl however some people complain about epoxy floors being slippery.
A: Raised cleanroom flooring typically has aluminum floor tiles on two-foot-high pedestals to allow air to pass thru the perforated floor tiles and flow back to the air return walls. Electrical conduit, gas and liquid piping can also be run under the floor. It is most often used in class 100 semiconductor manufacturing cleanrooms. Raised cleanroom flooring is the most expensive cleanroom flooring choice.
A: Industrial VCT (Vinyl Composite Tiles) flooring is the most economical choice for ISO-8 or class 100k cleanrooms. VCT tiles are precut in factory and are attached with adhesive to the existing concrete floor.
A: Polishing concrete includes an impregnating chemical sealant which hardens and densifies the concrete. This process can be acceptable to provide cleanroom flooring for ISO-8 / class 100k cleanrooms.
A: Carpeting traps large numbers of particulates. Any carpeting near the cleanroom will raise particulate counts within the cleanroom.
A: Cleanroom tacky mats are sticky mats placed on floor in front of entrance to cleanroom. They are designed to remove dirt from bottom of personnel’s shoes before they enter the cleanroom. This reduces the amount of dirt tracked into the cleanroom.
A: The cleanroom booties cover personnel shoes which prevents dirt from being tracked into the cleanroom.
