Sealants are a necessity for almost any construction project. Polaris currently offers four different sealants to see your project through its completion. The Polaris Ultimate Hybrid® Window and Entryway sealants are a green alternative that provide great adhesion, flexibility, and durability sans solvents and isocyanates. The Polaris Multi-Purpose Silicone Sealant® is a highly flexible, waterproof sealant that can be used for indoor and outdoor applications. The Polaris High Performance Expanding Foam® is a durable polyurethane sealant that eliminates air filtration. It is a paintable alternative to silicone, and is also a great option for applications that are susceptible to bowing, such as window and door installation.
