Buying Guide

Match diameter to your system

Measure fan and register ports and choose ducting or reducers that maintain proper airflow and minimize turbulence

Check material and layer construction

Aluminum single- or multi-layer ducts resist kinks and tearing better than thin foil; steel mesh or galvanized parts add rigidity where needed

Consider length and joiners

Select 25 ft or longer runs for continuous coverage and ensure clamps, reducers, or end caps are supplied to create secure, leak-resistant joins

Look for insulation or reflective options

Foam-core or reflective rolls improve thermal performance and reduce condensation on HVAC lines in unconditioned spaces

Confirm compatibility with code and venting use

Use heavy-duty aluminum or steel components for dryer and exhaust ducts to meet local fire and building codes and reduce lint buildup
