You speak…we listen! At CLWARD, we take customer feedback seriously, which is why we’re excited to introduce our newly modified S-Seal water-based duct sealant. Designed with contractors in mind, our updated formula features a higher viscosity while maintaining its signature easy spreadability. The result? A sealant that’s easier to apply, more efficient, and available in both smooth and fiber-reinforced options. Because sometimes, thicker is better!
