Protected Membrane Roof

Dow Building Solutions’ patented, energy-efficient STYROFOAM™ Brand Extruded Polystyrene Foam (XPS) Insulation is a critical component of protected membrane roof (PMR) technology, enabling a perfect foundation for a garden or green roof on the top of a building.

Protected Membrane Roofs: Dow’s Insulation Solution

In a protected membrane roof assembly – the foundation for green roofs  – the insulation is placed on top of the membrane, improving the performance and longevity of the roof system. Dow insulation solutions are perfect for PMR roof assembly because they offer:

  • Proven long-term performance – Membranes in PMR assemblies incorporating STYROFOAM XPS Insulation are still in exceptional condition 40 years after they were first installed.
  • Closed-cell structure – The closed-cell structure of the insulation prevents moisture penetration, which could otherwise compromise the roof’s thermal efficiency.
  • Thermal efficiency – STYROFOAM™ XPS insulation enhances thermal efficiency by reducing energy use and HVAC loads – just one way our patented solution helps lower a building's carbon footprint.
  • Superior temperature control – Closed-cell insulation helps keep the roof membrane’s temperature constant, reducing the harmful effects of freeze-thaw cycling and excessive heat, and extending the life of the membrane.
  • Durability and reusability – The high compressive strength and durability of STYROFOAM™ XPS Insulation stands up to heavy loads. What’s more, the insulation can be reused in many cases, decreasing the volume of material that ends up in landfills.
  • Versatility – A variety of compressive strengths and board styles are available to meet different roof specification needs.

Applications

Green Roof

invision_house_accordionThe sky's the limit for roof designs that combine energy efficiency and sustainability. That’s why one of the fastest growing segments in the commercial roofing industry is the design and construction of “green” or landscaped roofs. When planning an earth-friendly green roof, a roof that leaves the membrane protected with energy-efficient, reusable STYROFOAM™ Brand Extruded Polystyrene Foam Insulation is an essential component.

Plaza Deck

Plaza Deck ImageCommercial rooftops may be the building industry’s own “space race.” After all, the square footage is there, just waiting to be put to good use.

With the development of the protected membrane roof (PMR) assembly by Dow scientists more than 40 years ago, useful, practical and economical plaza roofs became possible. Today, plaza roofs featuring STYROFOAM™ Brand Extruded Polystyrene Foam Insulation support high-performance, multi-purpose areas such as decks, terraces, walkways and even gardens.
