Senior Editor at Builder, Jennifer Goodman, profiles a new product by GAF that is intended to eliminate leaky sidewalls. As more and more customers are looking ahead at sustainability and their environmental impact, many parts of the country are becoming more stringent with their energy codes and environmental practices.

They attach to structural exterior sidewalls and can be fastened to outside wall sheathing, metal, or masonry walls."
