Precast
Graphite Polystyrene (GPS) is an advanced foam material ideal for precast and cast-in-place concrete applications where high thermal resistance and compressive strength are required. Lighter than traditional materials and offering a higher R-value per inch, GPS helps simplify concrete forming, improve thermal performance, and reduce structural loads.
Our GPS foam is custom-cut to your project’s specs, making it easy to create complex shapes and repeatable forms. It’s commonly used as void fill, blockouts, and cores in everything from structural panels to detailed architectural designs.

Our Foam Products
Foam questions?
We've got answers.
Learn more about the applications for our foam products.
What types of foam products do you manufacture?
Our specialties are expanded polystyrene (EPS), expanded polypropylene (EPP), and graphite polystyrene (GPS), These products have many applications, and can be used in roofing, insulation, landscaping, stabilization, exterior siding, and more.
Do you offer custom foam manufacturing?
We do have the capability to customize our products to your specific needs. In addition, we offer custom packaging, either to ensure your product arrives damage-free, or for your own shipping and packaging needs.
Which types of foam are best for each application?
Most of our applications can be made with multiple foam types, and we’ll guide you to choose the best one for your requirements. Here’s a list of what we manufacture:
- Custom packaging: EPS or EPP
- Insulated shipping containers: EPS or GPS
- Precast: EPS or GPS
- Garage doors and door cores: EPP, EPS, or GPS
- Sheathing: EPS or GPS
- EIFS: EPS or GPS
- Geofoam: EPS
- 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.
