  • Patent number: 9702148
    Abstract: An underlayment product comprises a fibrous mat having an upper surface and a lower surface. A rubberized asphalt coating is applied to the lower surface of the fibrous mat and extends at least partially into the fibrous mat. In one heavyweight underlayment, an oxidized asphalt coating is applied to the upper and lower surfaces of the fibrous mat generally encapsulating the fibrous mat including the rubberized asphalt coating provided on the lower surface of the fibrous mat. The oxidized asphalt layers may be coated with a release layer such as talc, granules or a polymer. In a lightweight underlayment, a split release sheet or facer segmented to provide a releasable selvedge edge and incorporating a high traction polymer on its surface is applied to the rubberized asphalt.

  • Patent number: 6385934
    Abstract: A weatherproofing membrane having a high traction surface is used on a roof or other such location to prevent individuals from slipping. The weatherproofing membrane includes a facer sheet formed of a weatherproofing material and one or more polymer regions disposed on an upper side of the facer sheet. The weatherproofing membrane also includes a layer of modified asphalt disposed on the lower side of the facer sheet and a release backing disposed over the modified asphalt. The polymer is softer than the weatherproofing material and thus provides a higher traction surface than the weatherproofing material of the facer sheet. The polymer includes a low molecular weight polyethylene and an amorphous polyolefin (APO) in respective proportions ranging from about 50/50 to 90/10. The low molecular weight polyethylene and the APO are mixed hot and applied to the facer sheet, for example, using conventional coating techniques.
