Super Wind Resistant Seal Strip Design
Both our single layer asphalt shingles and double layer asphalt shingles contain a strip of factory applied adhesive that is
activated by the sun's heat after installation and seals each shingle to the next course. The seal strip also provides much of ashingle's resistance to wind uplift.
Shingles with factory-applied adhesive have a strip of clear polyester film applied to each shingle to prevent the sealing strips from bonding the shingles together when packaged. When the shingles are installed, the first step is tearing out the polyester film, then installed according to installation guide.
