All-phase consultation and technical expertise

Our insulation technical consulting team provides comprehensive engineering judgments, accurate and detailed CAD drawings, and a knowledge base of building codes and insulation application techniques focused on perimeter fire containment solutions without sacrificing design. We are the only mineral wool manufacturer that develops engineering judgments on PFC systems, and that is uniquely suited to evaluate conditions where NFPA 285 is a consideration.

High-performing products and systems

Thermafiber® FireSpan® and Thermafiber® Safing mineral wool insulation products have been extensively evaluated per ASTM E2307 standards. These evaluations confirm the insulation’s exceptional ability to act as a formidable barrier against fire and high-temperature gases, exceeding 2,000°F (1,093°C). These products are integral components of perimeter fire containment systems that have been thoroughly tested, listed, and certified by UL® and Intertek®.

Cost-saving insulation hanger systems

Our patented Thermafiber® Impasse® Hangers lock the perimeter fire containment system in place for faster, more accurate, and safer insulation positioning. With fewer hangers needed compared to traditional installation methods and employing less costly components, our Impasse® Hangers are a cornerstone of cost-effective building insulation solutions for enhanced fire containment.

Labor-saving systems

Our patented Thermafiber® Impasse® Perimeter Fire Containment Systems using Thermafiber® Impasse® Hangers streamline the installation of curtain wall insulation. This system significantly streamlines the process by reorganizing the traditional installation sequence into a more logical progression, saving valuable labor and time.

When Life Safety matters most

What is Perimeter Fire Containment?

A proper perimeter fire containment system helps save buildings, intellectual property and business capital, along with allowing the people inside the structure more time to escape in the event of a fire. Owens Corning® Thermafiber® is committed to providing solutions that help the commercial building professional confidently design, specify, and install durable systems for commercial structures.

Case Studies

Thermafiber Insolutions® at Work

Salesforce Tower

Thermafiber® drew from a repository of test data dating back to the 1960s, as well as third-party and internal test data specific to the building’s conditions. A third-party engineering firm conducted a parallel engineering analysis. Thermafiber Insolutions® reviewed drawings and provided engineering judgments to support the fire containment assembly system.

Thermafiber® worked with Benson Industries to develop an alternative assembly that would comply with building codes and then tested the assembly in time to avoid construction delays. The new system (CW-D-1037) was tested and approved in under a year.

The Insolutions team reviewed thousands of architectural drawings to meet the extensive code requirements and issued over two dozen engineering judgments. Thermafiber® mineral wool strategically protected critical fire spread areas—between floor slabs, within the curtain wall system, and on aluminum mullions. Custom hangers facilitated insulation attachment within the curtain wall, accommodating unique framing configurations.
