Insulation Intel® Webinar:

Insulating Combustible Pipes in Plenum Spaces

Wednesday, April 21 at 2:00 PM ET

Since plenum spaces house HVAC systems, they require airflow to operate successfully. This airflow creates an oxygen-rich environment that could become a potential fire hazard if exposed to flames. Ensuring mechanical systems in plenum spaces are insulated with fire-rated materials is important for both safety and system performance.

Fire safety codes regarding plenum spaces are nuanced and evolving, which is why we are hosting an Insulation Intel® webinar: Insulating Combustible Pipes in Plenum Spaces on April 21st, 2021 at 2:00 PM ET. Our hosts, Natalia Maximova from JM and Greg Newman from Insulation Midwest , will dive into the importance of insulating pipes in plenum spaces, current tests and code requirements for materials used in plenums, and what performance means in terms of fire safety.

The webinar will touch on the following topics before concluding with a live Q&A where you can bring your questions directly to our hosts:

  • What listed and labeled means
  • How materials are tested for flame/smoke ratings vs. multi-hour fire ratings
  • Why third-party verification is relevant
  • Comparison of insulating materials that can be used in plenum spaces
