A Top Priority

Your roof is a critical factor in the overall performance of the building envelope. Dow offers solutions for nearly any type of roofing method to help you achieve a longer lasting, energy efficient and sustainable roof.

Roofing Applications

Inverted Roof

In an inverted roof, insulation is placed on top of the membrane, enabling a perfect foundation for a terrace, garden or green roof on the top of your building. An inverted roof assembly can lengthen the life of the roof, contribute to sustainability and provide long-term cost savings.

Insulation for an inverted roof must:

  • Resist water absorption
  • Provide excellent thermal performance
  • Be unaffected by freeze/thaw cycles
  • Withstand surface traffic
  • Provide long-term protection to the waterproof layer
  • Be ballasted to prevent flotation
  • Be protected from UV and mechanical damage

Our STYROFOAM™ XPS Insulation and XENERGY™ XPS Insulation are critical components of inverted roof technology and capable of providing more than 40 years of near worry-free service.

If that’s not enough, here are the top 10 reasons to specify Dow XPS insulation in your inverted roof.

Conventional Roof

Unlike an inverted roof, insulation in a conventional roof lies under the protective membrane covering. Our conventional roof insulations and sealants provide long-term thermal performance, moisture resistance and can be reused.

Designed specifically for conventional roofing applications, Dow’s ultra-strong adhesives offer an alternative to metal fasteners with the added benefits of reduced thermal bridging and improved energy efficiency.

For flat roofs, we also offer solutions with a diminishing plane to create a gentle slope, significantly improving water drainage.

Tile and Clay Roofing

Looking for a high-performance adhesive for installing concrete and clay roof tiles?

TILE BOND™ is a single-component polyurethane adhesive that eliminates the problems typically found with other attachment methods like mortar, screws, wire ties and two-component foam systems.

TILE BOND™ works on a variety of roof tile jobs, including most low/flat, medium, high and two-piece barrel (cap and pan) profiles. TILE BOND™ works in both new and reroof applications. And it’s an excellent choice for patch and repair — as well as for specialty applications such as ridge, rake, valley and hip installations.
