Customer Questions & Answers

can this be used to vent a residential bathroom fan

Asked by: sweeney
I would not recommend it. There are other vent covers that would not require any jury-rigging to make it work If you choose to use it. Make sure that you have a hose leading to the vent from the fan. Attach a an HVAC reducer to the inside of the roof, directly under the vent. Be sure to attach the vent to the top of a flat or pitched roof. Do not mount this vent vertically.

13 in. x 5 in. Aluminum 8 in. Dia. Low Profile 50 sq. in. NFA Roof Vent in Mill Finish is rated 5.0 out of 5 by 3.
Rated 5 out of 5 by from Good buy These vents were very easy to install.I only choose them because the top can be screwed off ,making vent easier to position over cut hole. I'm a do it selfer who lives in the carribbean.The building code here only requires soffit vents.We have frequent hurricanes so I have to see how well these vents seal against horizontal rain.Plenty of sunshine so attics are usually very hot.Hoping for 20-30 degree drop in attic temps.

Rated 5 out of 5 by from Great buy!! Got these for my 2 story barn building. Since I don't have a ridge vent it gets pretty hot even though I have gable vents and windows on either end. So after installing these I cut the temp down to about 10 degrees. Despite negative reviews I don't have any problems with rain coming in. The directions tell you how to place it when mounting so I guess if you mount it wrong you'll get a leak. Great design for a good price.

Rated 5 out of 5 by from almost perfect This worked perfectly for venting my shop and the 100 sq ft addition I just did on the house. There was an overnight difference in the temperature of the rooms. The only thing I wished is that the "turtle back" style were still available. shipped quickly and arrived with no damage.
