Duct Insulation

Product Description

Duct insulation is a barrier that slows down heat transfer through duct walls, helping to maintain the desired temperature of the air inside the duct. This helps HVAC systems work more efficiently, and can also improve a home's energy efficiency, air quality, and prevent condensation.

Here are some things to know about duct insulation:

• How it works: Duct insulation works by trapping air bubbles or pockets of air among fibers, which are poor conductors of heat. Thicker insulation is generally more effective.

Types of insulation

Some types of duct insulation include:

• Ductwrap: This insulation is often made of mineral wool or fiberglass, and is easy to install. It has a foil-facing that reflects heat and acts as a vapor barrier.
• XLPE: This insulation comes in sheets and rolls, and can be installed using an adhesive.
• Polyurethane: This foam insulation is moisture resistant and has a high operating temperature, but its fire resistance is low.
• Rock wool: This insulation is made from melted rock spun into fibers, and is known for its fire and thermal resistance. However, it can be difficult to install due to its bulkiness and weight.
• Fiberglass: This insulation is made from melted glass fibers, and is popular for HVAC systems due to its low cost and ease of installation. However, it can be itchy and difficult to handle.
