EIFS
GPS boards are uniquely formulated to reflect radiant heat, dramatically boosting the material’s thermal resistance to achieve an R-value up to 20% higher than standard EPS at the same thickness. This superior efficiency allows architects and designers to specify a thinner insulation profile while meeting the most stringent energy codes, optimizing wall assembly design without sacrificing valuable space.
GPS boards are lightweight, dimensionally stable, and vapor-permeable, ensuring simple handling on the job site and supporting the crucial moisture management required for a durable, long-lasting, high-performance building envelope.

Details & Uses
GPS foam contains graphite particles that reflect heat, giving it a higher R-value per inch than standard EPS. Its thermal performance offers benefits when used in Exterior Insulation and Finish Systems (EIFS):
Enhanced energy efficiency with R-values up to 5.0 per inch
Allows for thinner wall assemblies while meeting energy codes
Lightweight and easy to handle for reduced labor time and installation costs
Vapor-permeable to support crucial moisture management within the wall
Dimensionally stable to prevent gaps and cracking in the final system
Contributes to a more sustainable build with less required raw material
Excellent compatibility with typical EIFS adhesives and finishes

- Roofing: EPS
- OEM: EPP, EPS, or GPS
Which type of foam is the best for my project?
If multiple foam types are able to be used in your project, we’ll discuss the benefits of each product and decide together what will be the best choice for your project.
Are your products sustainable or LEED-certified?
Many of our products can contribute to LEED points, depending on application and use.
Why use GPS in EIFS (Exterior Insulation and Finish Systems)?
GPS provides higher thermal resistance per inch than traditional EPS, improving the energy performance of EIFS walls.
Is GPS compatible with existing EIFS systems?
Yes, GPS can be used in place of standard EPS in most EIFS systems without requiring major modifications.
How does GPS enhance energy efficiency in EIFS applications?
Its graphite-enhanced structure reduces thermal conductivity, improving wall R-values and minimizing energy loss.
Is GPS lightweight and easy to install in EIFS applications?
Yes, GPS retains the lightweight and easy-to-handle benefits of EPS, with added thermal performance.
Can GPS meet continuous insulation requirements for modern codes?
Absolutely. GPS is well-suited for continuous insulation applications and can help meet stricter energy codes and green building standards.
