AEROFLEX Breathe-EZ®

Description

Aeroflex® Breathe-EZ® EPDM Duct Insulation is a fiber-free, closed-cell elastomeric foam insulation designed for HVAC ductwork applications. This plenum-rated insulation is available with or without a pressure-sensitive adhesive (PSA) backing, providing acoustic control, thermal efficiency, and moisture protection. Suitable for both duct lining and wrapping, Breathe-EZ® is microbial-resistant and non-particulating, offering a safe, quiet, and sustainable option for residential and commercial HVAC systems.
