US Patent 7452586 Floor covering

A temporary floor covering 10 that allows air and moisture to pass through the covering 10 is disclosed. The floor covering 10 has a first layer 12, a second layer 14 connected to the first layer 12, and a plurality of perforations 18 in the covering 10. The first layer 12 is typically made of a low-density polyethylene foam, and the second layer 14 is typically made of a polyethylene film. The perforations 18 extend through the first and second layers 12, 14 to allow air and moisture to pass through both the first layer 12 and the second layer 14. Additionally, an outer surface of one of the first layer 12 or the second layer 14 may have an increased coefficient of friction.
