Waterproofing Membranes

Not your ordinary roof

A roof’s work is never done. Sizzling temperatures. Frigid snow and ice. Winds and gales. Torrential rain. Throw in some hail, for good measure. A membrane roof could see it all in its lifetime (if not the same week).

Using roofing membrane science from Dow, you can embrace these difficult working conditions with flexible, long-lasting, waterproof performance for flat and low-sloped roofs.

Our scientists have been busy developing a portfolio of resins for roofing and waterproofing membranes. Their mission each and every day is to make sure flat and low-sloped roofs are protected from the extremes over a long life span:

Whether you’re working with systems based on thermoplastic polyolefins (TPO), polyvinyl chloride (PVC) or ethylene propylene diene terpolymer (EPDM), our roofing membrane science can offer:

  • Flexibility that lasts, even for high filler loaded flame retardant membrane
  • Long-term durability for long life expectancy
  • Weatherability/UV resistance that meets/exceeds appropriate industrial standards
  • Fire performance with halogen-free, low-smoke, low-ignitability, and low-fuel load options
  • Light color/cool roof formulations to reduce heat absorption
  • Multiple attachment options, including fully adhered, heat welded, mechanical, and/or ballasted systems
  • Cost Efficiency: Liquid cold applied on aged membranes to renovate and extend useful lifetime of the roof
  • Improved environmental and sustainability profile: Options manufactured without added solvent

Tell us about your roofing and waterproofing challenges. We love to go to extremes and find answers that work best for you.
