For the purpose of noise reduction, is this product better than the ThermoFlo 2000 SR Series? -Bryan Shaffer

No, if you are looking to really reduce noise you need to go with the insulated ducting found here: http://www.greners.com/i/fans-ventilation-filters/products/ducting-parts/thermoflo-srb-insulated-ducting.html The insulated ducting will also help keep temperatures more stable as it will not allow heat to escape the ducting. -Greners Staff
