Can this be used for a range hood?

Asked by: Tranda
This is only for heating or air conditioning lines. You need an aluminum or galvanized duct for a range hood. You can remove the mylar flex duct in this product and slip the outer insulation over a metal duct if you require insulation.

Can i use this as a exhaust for my dryer

Asked by: Jeremy
Jeremy, I recommend that you don't use this item, because the insulation will keep the heat in to much and possibly melt the black plastic sleeve, Recommended items would be a metal vent or the vinyl dryer vent. Have a Good Day Johno

6 in. x 25 ft. Insulated Flexible Duct R6 Silver Jacket is rated 4.4 out of 5 by 138.
Rated 3 out of 5 by from It is nice duct but no way was it 25ft long. My main trunk runs right down the middle of the hou... It is nice duct but no way was it 25ft long. My main trunk runs right down the middle of the house and the air register is along the outside wall. It is 23 feet from the outside wall to the main trunk. I thought a 25 ft piece of duct would reach the needed 23 feet with room to spare but it was about 8 inches too short. I pulled and tugged but it just would not reach. Ended up having to add another piece. Maybe I just got a bad box but no way was it 25 feet and that caused me a great deal of grief, a lot of swear words and some extra cash that I didn't want to part with.

When buying something like a heat pump/ AC unit you can't find anyone to install it, leaving you to try to figure it out and yet still no cool air and its getting hotter. What is a person suppose to do? We live pay check to pay check and are trying to upgrade the house I was raised in, raised my kids in, and now my grandkids but it doesn't help when you can't get the right information or someone to help install it. The flex tube duct work wasn't do what is needed.

Following an upstairs flood, I had to replace my air duct since a lot of water went down the old air duct. This duct, plus a couple of zip-ties made an easy job! To cut it, I used a box-cutter knife, plus a pair of wire cutters when I got to the coiled wire of the duct. If needed, a little extra silver/foil duct tape can help ensure it doesn't leak air around the seal, sort of a belt & suspenders approach to ensuring the duct doesn't slip off the zip-tie connections.

Rated 5 out of 5 by from Very easy to work with. I am 63 years old. I was able to work with this product an install it in a crawl space that I had only 3 feet height at the most ! I used the materials for installation that I bought at Home Depot to go with the flexable duct work . I redid all my duct work for my house !t took me longer the most young people would of taken but in the end my heating system works great !! I found everything I needed to do the job right at Home Depot ! By the way I am a women and following instructions found on google I saved myself a lot of money ! Women can do a lot themself using Home Depot & Google to save money.

This product is what it is, but if you live on the west side of the mountains in WA state it does not meet minimum energy code requirements of R8. If you live in an area that R6 is code compliant it is an average product that does its intended purpose.
