The Lambro JIP-1010 duct insulation sleeve offers an effective thermal barrier for standard 10-inch round flexible or rigid heating and cooling ducts. This heavy-duty sleeve consists of a thick fiberglass insulation core surrounded by a robust black polyethylene vapor barrier. It is specifically designed to minimize energy loss in unconditioned spaces like attics, basements, or crawlspaces.
By delivering a solid R4.2 thermal resistance value, this continuous 10-foot insulation blanket prevents ductwork from sweating due to temperature differentials. HVAC installers and energy efficiency contractors select this sleeve to retrofit existing uninsulated ducts or to add extra protection over newly installed venting lines. The integrated vapor barrier plays a vital role in preventing moisture infiltration into the fiberglass layer.
The sleeve can be slid smoothly over circular duct lines, making field installation quick and efficient. It satisfies common residential and light commercial venting needs, ensuring compliance with general air handling layout designs. Always confirm your duct's outer diameter dimensions to ensure the 10-inch size slides over cleanly without compressing the internal insulation material.
