HVAC Duct Insulation

RadiantGUARD® HVAC Reflective Duct Insulation for DIY Users

RadiantGUARD® HVAC Reflective Duct Insulation provides an excellent thermal break and vapor barrier for your existing air ducts.   Composed of 99% pure aluminum, the foil surface reflects away summer heat from your cool air ducts and resists heat loss from warmer ducts in the winter time.

Benefits:

• Environmentally safe.

• Non-toxic, non-carcinogenic and no itchy fibers.

• Unaffected by moisture, it inhibits mold, mildew and fungi growth. 

• Being lightweight and flexible, it is easily installed around the most complicated air duct systems 

• When sealed properly, aids in reducing duct leakage

• Achieves an R-Value of 4.2 when applied directly on ducts.

Achieve an R-Value of 6.0 when used in conjunction with a 3/4" air space between the duct and the insulation.  This air space is easily achieved by cutting 2" wide pieces from the insulation and double-wrapping around the duct every 24".
