Buying Guide

Match duct diameter to system

Choose the listed 8-, 10- or 12-inch sizes to align with your fan and register airflow to avoid pressure loss

Prefer thicker construction for longevity

Four-layer or heavy-duty aluminum resists kinks and tears better than single-layer foil for repeated installations

Check flexible length vs. run layout

Use 25-foot lengths for longer runs or plan for couplers and supports if you’ll cut the duct to size

Consider crush and kink resistance

Sturdier wall construction reduces airflow restriction and sagging in horizontal runs

Mind compatibility with fittings

Confirm collar dimensions and use proper clamps or tape rated for HVAC to ensure airtight connections
