Patent ID: 7207136

Claim:
A heat-reflective and heat-absorptive ground temperature controlling ground cover for placement on a substrate, said ground cover comprising: a substantially continuous sheet formed of a layer of water permeable scrim material having opposed major faces, said scrim material comprising an open, spaced apart mesh weave of intersecting warp and weft strips forming a substantially continuous covering defined by said mesh weave, one only of said major faces having a discontinuous lace coating thereon and in intimate contact therewith, covering between about 15% to about 65% of said major face having said coating, said coating having either a heat-reflective or heat-absorptive characteristics, said warp and weft strips having on the other of said major face, opposed to the face having said lace coating, either heat-absorbing or heat-reflecting properties opposite to the heat-reflective or heat-absorptive properties of said lace coating, characterized by at least about 15% to about 65% of at least one of the warp and weft strips being provided with a material capable of rendering said at least one of the warp and weft strips heat-reflective or heat-absorptive.
