EIFS
EPS (Expanded Polystyrene) is the most widely used insulation material in EIFS (Exterior Insulation and Finish Systems). Known for its reliability, cost-efficiency, and long-term performance, EPS helps deliver continuous insulation, moisture control, and design flexibility in both residential and commercial exterior wall systems.
Whether you’re working on new construction or retrofit projects, EPS offers predictable performance and versatility — from standard insulation boards to custom architectural shapes.

Details & Uses
Suitable for both commercial and residential applications, EPS provides multiple advantages when used in EIFS construction:
- Continuous insulation
- Stable, long-term R-value
- Moisture protection
- Ease of modification
- Lowest cost per R-value inch
- Meets or exceeds EPS specs for EIFS systems
- Meets or exceeds requirements of type 1 EPS in ASTM C578
- Third-party certified with RADCO
EPS EIFS Boards
EIFS boards are ideal for exterior wall insulation and retrofit construction. Our EIFS Board, also known as “Aged Board,” is cut to specifications of 24” x 48” and bagged in increments of 18” for your convenience.
EPS EIFS For Architectural Shapes
EIFS shapes are ideal for cornices, arches, columns, window/door trim, special moldings, or other decorative accents. Creative Foam’s EIFS Board can be fabricated into a variety of shapes for architectural styling and design, custom cut by our CAD drawing team per blueprints or individually designed to suit our customers’ needs.

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.
What is EPS used for in EIFS systems?
EPS serves as the insulation layer in EIFS (Exterior Insulation and Finish Systems), enhancing thermal performance and surface uniformity.
How thick can EPS panels be for EIFS?
Typical thickness ranges from 1” to 4”, depending on energy code requirements and design specifications. Some brands have even approved EPS thicknesses up to 12”.
Is EPS in EIFS fire-rated?
EPS must be used with code-compliant fire-resistant barriers or coatings, as it is combustible in its raw form. However, a flame retardant is added to EPS during the manufacturing process to inhibit the spread of a fire and complement other barriers and coatings in their fire resistance.
Can EPS EIFS be used in both residential and commercial buildings?
Yes, EIFS is suitable for a wide range of applications, from homes to high-rise buildings.
Does EPS improve building energy performance?
Yes, EPS in EIFS provides continuous insulation, reducing thermal bridging and energy loss.
