More than meets the eye

The cell matrix of EPS foam allows the intrusion of water over time. The closed cell structure Styrofoam™ Brand XPS Insulation protects better in critical applications.

Closed cell structure absorbs less water than EPS products

XPS holds R-value better than EPS when water is present

Absorbed water can cause damage in freeze/thaw conditions

Grey Styrofoam™ Brand XPS beyond blue

Without compromising on quality, durability or thermal performance, we are introducing a new Styrofoam™ Brand XPS formulation that reduces global warming potential (GWP) and greenhouse gas (GHG) emissions.

Move forward with grey Styrofoam™ Brand XPS

GWP Reduction

Our history is rooted in innovation – allowing us to deliver better, more-sustainable technology for modern building needs. The reduced GWP Styrofoam™ Brand XPS is another example of our long-term commitment to global sustainability and environmentally compliant building solutions.


By January 1, 2021, DuPont™ Styrofoam™ Brand XPS Boardstock Insulation will begin transitioning to a reduced GWP grey color in Canada and select U.S. states1.


The change is easy to identify; we are modifying the color of reduced GWP Styrofoam™ Brand XPS from the traditional blue to the new grey2. If you're in select U.S. states or Canada, you'll see the change by January 1, 2021, with plans to expand the product offering going forward.


Above and beyond ensuring environmental compliance, we're continuing to advance our 2030 Sustainability Goals and invest in global efforts and technology innovations to help you design and build energy-efficient, resilient and durable structures in this rapidly changing world.


New color. Same value.

When you're protecting all six sides of the building envelope, the Styrofoam™ Brand product family has long been the choice for solid performance and energy efficiency. The new, reduced GWP Styrofoam™ Brand XPS formulation maintains the high levels of performance you've come to expect from the Styrofoam™ Brand.

Performance is not a color

Shield Therm

Reduced GWP Styrofoam™ Brand XPS delivers the same R-value3 — R-5 per inch thickness — for long-term thermal performance. The grey color lets you know it was made with a reduced global warming potential (GWP) formulation.

Rain / Sun

With the same thermal performance, moisture resistance, durability and easy to handle, this reduced GWP Styrofoam™ Brand XPS Insulation along with our complete building envelope solutions, delivers protection that's a sure fit for all six sides.


The reduced GWP Styrofoam™ Brand products will be available in the first regions by January 1, 2021. This includes select U.S. states and across Canada, with plans to expand the product offering going forward. Refer to the Styrofoam™ Brand XPS Code Report ICC-ESR 2142 for details.


Beauty below the surface

The new grey color of reduced GWP DuPont™ Styrofoam™ Brand XPS is perfect for modern open-joint cladding, rainscreens or any design that calls for exterior, continuous insulation.

Styrofoam™ Brand XPS is ready to mingle


When you need a dark reveal behind open-joint façade systems and rainscreen designs, the new grey Styrofoam™ Brand XPS has you covered. These rigid foam boards provide durable and highly efficient continuous insulation (CI) — preventing thermal bridging and adding great energy performance and sustainability to the structure.


Styrofoam™ Brand XPS resists stains, while other products can get unsightly dark stains. These stains can also be seen through the cladding on inadequately insulated wood and steel stud walls.


When you use new grey, reduced GWP Styrofoam™ Brand XPS, you will get aesthetics, performance and sustainability.
