4” Blue Flex R8
$85.00
4” Blue Flex R8 insulated flexible duct, primarily used in HVAC systems for superior thermal efficiency and antimicrobial protection.
- Dimensions: 4 inches in diameter and typically sold in 25-foot lengths.
- Insulation Rating: R8, which provides roughly 50% more thermal resistance than standard R4.2 ducts, making it ideal for energy-efficient homes and extreme climates.
- The "Blue" Difference: The blue jacket signifies antimicrobial properties. It often uses Agion® silver-based technology in the inner liner to inhibit the growth of mold, mildew, and bacteria.
- Materials: Features formaldehyde-free fiberglass insulation (often from Johns Manville) and a metalized polyester vapor barrier with "rip-stop" reinforcement.
