Key Benefits

Supports Indoor Air Quality (IAQ)
Formaldehyde-free and low VOC
Proven Performance
Class A fire rating and proven energy efficiency and sound absorption for interior comfort
Installer Comfort
Low dust and easier to handle, cut and install

HVAC insulation is vital for creating interior spaces that are comfortable and energy efficient because it helps control two critical factors: sound and temperature.

  • Sound absorption
    The acoustical properties of HVAC insulation help reduce sound that can travel in and around ducts.
  • Temperature control
    HVAC insulation keeps temperatures steady, so cool air stays cool and warm air stays warm. It also helps the system work more efficiently, which means lower utility costs.

By choosing low-VOC, formaldehyde-free and CERTIFIED asthma & allergy friendly® insulation, you can help reduce indoor air pollution, improve air quality and have peace of mind you’re creating spaces that support the well-being of others.

HVAC Insulation

HVAC insulation delivers comfort and efficiency. Insulation helps make HVAC systems work more efficiently and reduces the noise associated with ductwork.

Why HVAC Insulation Matters

In the normal course of operation, HVAC ductwork can be noisy. Loud cracks and booms can be distracting and discomforting in the workplace or in the home. HVAC ducting insulation has acoustical properties that help absorb these noises and minimize sound transfer.

HVAC insulation also has thermal properties, which improve the overall temperature control of the system, reduce energy loss, and help the system operate more efficiently — meaning an overall reduction in utility costs.

Condensation Control

When uninsulated equipment runs at below-ambient temperatures, condensation can form. Proper insulation — along with a vapor retarder — is a crucial part of a complete condensation control system, which will minimize condensation build-up.

How To Choose HVAC Insulation

Which type of HVAC insulation is right for your project? Here are the different types of HVAC insulation and their uses: 

  • Duct Liner: delivers thermal and acoustic performance when used to line sheet metal ducts. 

  • Duct Board: delivers acoustic and thermal control, and is fabricated into the duct itself.  

  • Duct Wrap: delivers thermal performance to increase efficiency when installed on the exterior of sheet metal ductwork, and can help control condensation with the inclusion of FSK facing.
