Roof Insulation Systems
Thermal performance for efficient roof assemblies
In roof systems, weight and performance go hand in hand. EPS insulation helps reduce load on the structure while maintaining stable long-term R-value.
It’s commonly used in low-slope roofing, tapered systems, and retrofit projects where efficiency and ease of installation matter.
Wall Insulation Systems
Continuous insulation that supports the full building envelope
Wall systems rely on continuity. EPS insulation is used across exterior assemblies to help reduce thermal bridging and maintain more consistent interior conditions.
From air and water-resistive barrier (WRB) functionality to high compressive strength, Atlas wall solutions are specified to meet code and built to last. Across residential framing and commercial wall systems, they provide adaptable performance for different wall assemblies, design requirements and moisture control strategies.
Below-Grade Insulation Systems
Underground performance you can specify with confidence
Below-grade applications demand insulation that maintains its R-value, resists moisture, and compressive strength under sustained soil loads. Atlas expanded polystyrene insulation is engineered to meet those demands from below-grade foundation walls to underslab assemblies.
It helps maintain thermal performance while supporting long-term stability in environments that are often more demanding than above-grade assemblies.
Geofoam Structural Solutions
Lightweight fill for projects where weight matters most
EPS geofoam removes the limitations that traditional heavy fill creates. It replaces traditional materials with a lightweight, engineered solution that reduces stress on structures and underlying soils. The result is more control, faster installation, and predictable performance in conditions that are anything but simple.
Why Choose EPS from Atlas Molded Products
We don’t treat EPS as a one-off material.
It’s used as part of a broader approach to building performance, where insulation, structural fill efficiency, and real-world application all need to work together.
From roof and wall systems to below-grade conditions and structural fill, our products are designed to adapt to different environments while maintaining consistent performance. This allows designers and builders to simplify material choices and carry that performance across the entire project.
How Compatibility Drives Performance
Efficiency Extends Beyond the Building Systems
EPS supports building performance by doing more with less.
Atlas Molded Products manufactures EPS using low-GWP and zero ozone depletion potential (ODP) blowing agents, with no CFCs, HFCs, HFOs, or HCFCs. This lightweight building material itself is 100% recyclable nationwide at over 700 EPS recyclers, including Atlas facilities to help divert material from landfills while supporting a more circular approach to production.
In life cycle assessments (LCAs), EPS products are shown to provide insulation and protection with a lower overall environmental impact compared to many alternative materials.
