Questions & Answers

Can you cut this duct to size - if I need only 17 of the 25 feet?

Asked by: Anonymous
Yes. Can be cut to size. Just peel back insulation and clamp flexible tubing onto outlet or whatever other connection you have. Then fold insulation back into place. Works great.

Can this be turned into 2 pieces?

I need about two 8 foot runs. I just want to make sure the ends are not fabricated and that the entire length is meant to be utilized... Thanks
Asked by: CTNIC
Yes, Just cut it and trim back the outside insulation is needed.

What is the suggested vent cover for this duct?

I need to vent two bathroom fans out and the soffit seems like the best choice. Is there a certain brand or model of vent (that keeps debris and bugs out) that will fit well with this ducting?
Asked by: CTNIC
I depends if you are putting it in a wall or a soffit.

Can I use this duct to extend my outdoor electric dryer vent outside where the steam will clear my patio cover?

Need to try and prevent dryer steam from collection on the underside of my patio cover causing mold.
Asked by: JB
NO. No dryer venting can have anything but metal. That's code everywhere.

Rated 5 out of 5 by from Good for bathroom vent fans I bought this after seeing a like-product used on This Old House to create a roof vent for bathroom fans. It works great and is easy to use/cut. This duct is compressed inside the box when you buy it, so be ready for it to continually "ooze" out of the box when you first open it. I only wish the Home Depot site had worked better, because it said the product was not carried in my local store, when in fact, it was. I happened to go down the ducting aisle a week after I bought this online and paid for shipping, and there were plenty of boxes of the ducting available in-store.

Rated 4 out of 5 by from Easy, clean, strong, effective Replaced non-insulated bathroom flex-ducts with this stuff. It comes compressed in a box about 3-ft long which is real handy in tight spaces. The outside silver-jacket and inner flex duct materials were both a lot stronger and tear-risistant than I expected. It does take a few minutes and/or gentle massaging to reach full length, but this wasn't a problem. Highly recommend this material for similar applications, though be sure to get ALUMINUM or plastic couplers, not galvanized! Also, since the material is so strong, you'll have a hard time w/ any joints that aren't slightly undersized, the duct does NOT stretch larger (a good thing).

Rated 5 out of 5 by from Great Product and Excellent Value I bought this to use on a new bath ventilation fan. The ducting for the previous fan not insulated. The builder simply buried it under the sprayed insulation. I looked on the HD website and was amazed that this insulated ducting was a much better value then plain ducting. I only used about half the ducting so I have more for when I do the other bath fan. This duct is easy to work with and appears to be high quality.

Needed a flex hose to install an exhaust fan in our bathroom and didn't really want to worry about condensation forming on it in the winter. I found this on HD's website and figured I would give it a try. Worked very well, easy to handle and cut to size. I was worried it may have been too easy to tear the inner hose, but it worked just fine. Would recommend to anyone wanting to install a fan that needs a long run of insulated flex hose.
