Weatherproofing membrane having high traction surface |
摘要 |
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.
