Outmatch the Elements

For over 35 years, the GSSI Sealants brand has been the go-to solution for sealing metal buildings worldwide. Our butyl tapes are UL-classified and are manufactured in all common sizes for metal roofing applications.

Choosing a reliable substrate seal is essential to ensuring homeowners and business owners can enjoy the long life of their metal roofs. When a sealant fails, the roof fails to protect the building from moisture damage or internal temperature fluctuations. Making the right choice can mean the difference between a roof lasting 15 years and one that lasts over 60 years.
