    Abstract: Ice and water barrier films are provided which comprise an adhesive layer comprising a rubber blend of polyisoprene and a styrene-isoprene-styrene (S-I-S) block copolymer rubber. In some embodiments, the adhesive layer may comprise polyisoprene and the S-I-S block copolymer in a weight ratio of between 70:30 and 88: 12 and the total combined weight of polyisoprene and the S-I-S block copolymer may be between 36 wt% and 51 wt% of the adhesive layer. In some embodiments, the adhesive layer may comprise at least 10 wt% of a plasticizer and between 20 wt% and 60 wt% of a tackifier. In some embodiments, the adhesive layer has a low Tg, typically less than -20°C, more typically less than -40°C, and more typically less than -50°C. In some embodiments, the ice and water barrier film passes the Nail Seal Ability Test performed according to ASTM D1970.
