Low Density Concrete Roof Insulation

Elastizell supplies a cellular concrete roof insulation system that incorporates encapsulated EPS to provide a lightweight, durable insulation solution for commercial and institutional roofing applications. For more than 50 years, Elastizell has provided this specialized material solution to contractors and licensed installers across North America.

Unlike traditional insulation systems, Elastizell cellular concrete creates a monolithic insulating layer that encapsulates expanded polystyrene (EPS) within a cellular concrete matrix. This system delivers reliable thermal performance while providing a stable substrate for roofing assemblies.

Elastizell works with a network of qualified installers who place the material in accordance with project specifications and applicable building standards. Contact us today to learn more.

Elastizell offers a roof insulation system based on cellular concrete technology. The system combines lightweight cellular concrete with encapsulated EPS insulation to create a durable, insulating roof assembly suitable for reroofing and new construction. Key characteristics of the Elastizell system include:

• Lightweight cellular concrete that reduces structural loading
• Encapsulated EPS insulation integrated within the system
• Fire-rated roof insulation assemblies
• Compatibility with common commercial roofing membranes
• Wind uplift performance when used within tested roof systems
• Monolithic placement that creates a continuous insulation layer

This system is commonly used in roof insulation replacement and restoration projects, particularly on commercial, institutional, and industrial buildings.

Elastizell cellular concrete materials are produced to meet recognized industry standards and are supported by testing and approvals, including:

• ASTM C869 for cellular concrete materials
• Underwriters Laboratories (UL) fire-rated roof assemblies
• International Institute of Building Enclosure Consultants (IIBEC) recognition
• Membership in the American Concrete Institute (ACI)

These standards help ensure that Elastizell cellular concrete performs consistently when incorporated into properly designed roof insulation systems.

Elastizell functions as a materials supplier, providing cellular concrete technology and technical support for roofing professionals. Our team works with architects, engineers, contractors, and licensed installers to provide information on specifications, testing data, and insulation system applications.
