16" x 25 ft. Insulated Flexible Duct, R 4.2

Installed in my attic. Replaced the old 16" duct where my dog(?) had laid on top ruining it. Easy to install.

Great product and is even more flexible than I'd hoped.

This was just what I needed to complete my whole-house fan project. I ordered 25' so I could cut it in half in case I wanted to use it for 2 separate fans. The ducting is well insulated and easy to cut-to-length. Only time will tell how it holds up.

Product was easy to use, easy to cut and place in Hvac return line.

great quality,
