Weatherproofing Buildings with Silicone Sealants

Weatherproof your construction with silicone sealants, coatings, and more

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.

From long-lasting sealants featuring versatile movement capabilities and precise color match, to breathable silicone elastomer coatings that fight seasonal thermal expansion-contraction, to pre-formed sealants that offer a more efficient way to repair failed building weatherseals, our weatherproofing solutions give you competitive edge in protection and performance.

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
  • Easy application via multiple methods
     

Enabling many of the world’s tallest buildings
Of the world’s tallest buildings, the large majority contain Dow silicones
