Weatherproof your construction with silicone sealants and coatings

Usher in greater sustainability and reduce lifetime costs with high-performance weatherproofing solutions for your entire building envelope. Whether renovating or building new, you can stop air and water infiltration to achieve your energy-efficiency goals with our broad range of silicone sealants, coatings and pre-formed sealants.

Across all weatherproofing applications, our silicone solutions offer significant benefits such as:

Excellent durability for reduced call-backs
Exceptional breathability and water repellency
Great UV stability, weather and temperature resistance
Increased movement capability over a wide range of temperatures
