Abstract
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.
Claims17
A floor covering comprising:
- a first layer having a first surface and a second surface, the first layer being made of a polymeric foam material comprising a low-density polyethylene foam;
- a second layer having a first surface and a second surface, wherein the second layer comprises a film having low-density rich properties at the second surface of the second layer, and high-density rich properties at the first surface of the second layer, the second layer being connected to the first layer;
- and,
- a plurality of perforations extending through at least a portion of the first layer, from the first surface of the first layer to the second surface of the first layer, and a portion of the second layer, from the first surface of the second layer to the second surface of the second layer, to allow air and moisture to pass through both the first layer and the second layer,
- wherein each of the perforations comprises a narrow, elongated slit in the floor covering having sufficient engagement between opposed edges of the perforation to prevent particulates from passing through the floor covering.
An insulating flooring substrate comprising:
- a first polymer foam layer;
- and,
- a second polymer film layer in contact with the first polymer foam layer, wherein the second layer has a first tacky surface, the first tacky surface having an increased coefficient of friction, the second layer having high density rich properties at the first surface thereof, and low density rich properties at a second, opposed surface thereof, the second surface contacting the first layer,
- wherein the substrate has a second tacky surface at an opposing surface of the substrate to the first tacky surface, the second tacky surface increasing the coefficient of friction of the opposing surface of the substrate, and wherein the substrate has a plurality of perforations through the substrate, the perforations extending from an outer surface of the substrate to an opposing outer surface of the substrate, the perforations allowing air and moisture to pass through the substrate.
A temporary floor covering comprising:
- a first layer made of a low density polyethylene foam;
- a second layer made of a polyethylene film, the second layer comprising a co-extruded film having low density rich properties at an inner surface thereof, and high density rich properties at an outer surface thereof, the inner surface contacting the first layer;
- and,
- a plurality of perforations in the covering, the perforations extending through the first and second layers to allow air and moisture to pass through both the first layer and the second layer.
A temporary floor covering comprising:
- a first layer made of a polyethylene foam;
- a second layer made of a polyethylene film having low density rich properties at an inner surface thereof and high density rich properties at an outer surface thereof, the first layer being joined to the second layer at the inner surface of the second layer;
- and,
- a plurality of perforations in the covering, the perforations extending through the first and second layers to allow air and moisture to pass through the first layer and the second layer.
