Imperial R8.0 25 ft. L X 4 in. D Silver Poly Duct

<p>This imperial insulated flexible duct is ideal for use with heating, ventilation, and air conditioning systems. Its 2-ply polyester laminated inner core is constructed with supportive, non-corrosive coated wire. A blanket of fiberglass insulation surrounds the core which helps to reduce heat loss and condensation, and a silver metalized outer jacket with reinforced scrim surrounds the fiberglass insulation for durability. Because of its flexible nature, this duct can be installed in hard-to-reach areas without the need for elbows, and it can be used in place of galvanized pipe in most applications. The easy-to-install flexible polyester duct is intended for use wherever UL 181/ULC-S110 standards for class 1 air duct is required. It measures 4-in x 25-ft and features an insulation R-value of 8.0. Check your local building codes prior to installation. </p><b>Features</b><ul><li>Duct can be cut to length as needed</li><li>Oversized core for a seamless fit on collars and register boxes</li><li>Excellent material</li></ul><b>Specifications</b><ul><li><b>Color:</b> Silver</li><li><b>Diameter:</b> 4"</li><li><b>Length:</b> 25'</li><li><b>Material:</b> Poly</li><li><b>Country of Origin:</b> USA</li><li><b>Weight:</b> 9.13 lbs</li></ul>- SKU: ACHR182052
