Customizable Solutions for Complex Builds
Insulfoam EPS building components are engineered to simplify construction while expanding what’s possible in design. Whether you’re creating detailed architectural features, forming precise concrete shapes, or enhancing wall system performance, EPS offers a lightweight, versatile alternative to traditional materials.
Custom Architectural Shapes
Bring designs to life with EPS shapes that replicate the look of stone, wood, and concrete at 30–40% lower cost. Insulfoam can evaluate producing custom shapes and sizes based on your specific requests. The lightweight and easy to install EPS reduces labor costs while supporting design precision for commercial applications like resorts, retail spaces, and branded environments.
Precision Concrete Forming
EPS block-outs help you create voids and detailed shapes in concrete. Used in place of or alongside traditional wood and steel forms, EPS allows for greater accuracy and flexibility. Once the concrete cures, the EPS is removed, leaving behind clean, consistent results that make it ideal for complex pours and custom designs.
High-Performance EIFS & Stucco Solutions
Available in a wide range of sizes, shapes, and densities, Insulfoam EPS offers stable R-value, excellent dimensional stability, and moisture resistance for a variety of exterior finishes.
Across every application, EPS helps reduce costs, streamline installation, and improve building performance. With its combination of strength, flexibility, and efficiency, Insulfoam EPS components are built to meet the demands of today’s construction challenges.

Simple DIY, Serious Energy Savings
Nearly 90% of U.S. homes are under-insulated, according to the North American Insulation Manufacturers Association (NAIMA). Therefore, most homeowners can reduce energy demands and improve their home’s comfort with the right insulation upgrades.
Expanded polystyrene (EPS) insulation offers a simple, effective solution for DIY projects throughout the home. Lightweight, easy to cut, and versatile, EPS can be installed in core areas like the attic, garage, and basement to help reduce energy loss. In fact, the U.S. Department of Energy estimates that proper insulation can lower energy bills by up to 20%.
Start with the Garage
As the largest uninsulated surface in a home, the garage door is a major source of energy loss. Installing a pre-configured EPS garage door insulation kit is quick and effective. These kits can be installed easily with common household tools.
Seal Energy Loss in the Attic
A properly insulated attic helps promote indoor comfort year-round. EPS panels can be installed across attic floors, walls, and ceilings to help prevent heat loss in the winter and keep warm air out in the summer. EPS is easy to work with and can be cut to size using basic tools like a utility knife or saw. Panels can be secured with simple fasteners, making attic insulation a highly approachable weekend project.
Protect Basements and Below-Grade Spaces
EPS insulation also performs well in basements and other below-grade applications. Its closed-cell structure resists moisture while allowing the material to breathe, helping reduce the risk of mold and mildew growth.
EPS is ideal for insulating foundation walls and other areas prone to damp conditions, delivering long-term thermal performance.
Whether you begin in the attic, garage, or basement, these simple upgrades can make a noticeable difference in comfort, efficiency, and cost savings.
