The specific requirements in terms of floors for clean rooms refer to: wear resistance - important feature primarily in terms of risk of generating particles by erosion traffic (even if it is low because of the type of activity), the coefficients of non -retention and non-dust emission to be lower then a limit value (air "wash" floor area), the resistivity across the finishing material must be below the allowable standards. In addition floors should be provided with sanitizing profiles. The main types of flooring for clean rooms used are:
- Epoxy floors
This type of flooring is made of two layers: the wear layer and equalization layer.
The equalization layer is composed of epoxy resin and quartz sand in excess which is confering the floor resistance to mechanical shock. Depending on the thickness of equalization layer, the resistance to mechanical shock increases from medium to high.
The wear layer consists of epoxy resin compound that provides protection to wear and chemical attack.
This type of flooring complies with the requirements of GMP for all classes: A, B, C or D.
- PVC floors
This type of floor is achieved by applying a special PVC carpet.
Depending on requirements this can be: electrostatic, antibacterial, conductive, dissipative, etc.
