Material Options

Material prices below are national averages; availability in Raleigh may shift costs slightly.

Material	Cost/Unit	Pros	Cons	Best For
Flexible Duct (Flex Duct)	$4 - $8 per linear foot installed	Cheap, fast to install, flexible routing around obstacles, widely available	Loses efficiency when kinked or sagged, shorter lifespan (10-15 years), harder to seal	Branch runs in accessible attics, budget-conscious repairs, short runsCheap, fast to install, flexible routing around obstacles, widely available
Sheet Metal (Galvanized Steel)	$12 - $25 per linear foot installed	Durable (40+ year lifespan), smooth interior for maximum airflow, takes mastic sealant well	Higher cost, heavier and harder to route, conducts sound	Main trunk lines, commercial applications, high-performance systemsDurable (40+ year lifespan), smooth interior for maximum airflow, takes mastic sealant well
Fiberglass Duct Board	$10 - $18 per linear foot installed	Built-in insulation (R-4 to R-6), lightweight, quieter than metal	Interior liner can crack and release fibers, harder to repair, not ideal in humid crawl spaces	Conditioned attic spaces, commercial buildings, systems with quietness requirementsBuilt-in insulation (R-4 to R-6), lightweight, quieter than metal
Insulated Flexible Duct	$6 - $12 per linear foot installed	Combines flex routing with R-6 to R-8 insulation in one product	Bulkier than uninsulated flex, still prone to efficiency losses from bends	Branch runs in unconditioned attics or crawl spaces where insulation is neededCombines flex routing with R-6 to R-8 insulation in one product
Spiral Round Duct	$15 - $30 per linear foot installed	Extremely smooth interior (lowest friction loss), visually attractive for exposed installations	Highest material cost, requires careful sizing and layout design	Exposed basement or industrial-aesthetic installations, high-efficiency systemsExtremely smooth interior (lowest friction loss), visually attractive for exposed installations
