2x4 Interior Walls with 8' Ducts & 4' Plumbing Stacks - HELP!
Comments (1)If you live in a cold climate, venting anything but a stink pipe through the roof is a slippery slope...literally....picture a snow covered roof in the winter...now add warm air exiting the roof from a bathroom or dryer or kitchen exhaust fan...the warm air thaws the snow around the vent, then when you turn the fan off, the snow re-freezes, becoming ice, causing ice damming, resulting in excessive moisture and/or a leaky roof. You are much better exhausting warm air out the side of the house or out a gable. Regarding the PVC drain pipes, they're almost exactly the same dimension as a 2x4, so they fit, but just barely. You need to make sure your cut-outs are centered, but even if they're not, you can fur out the wall in question with strapping or "one-by". As for venting the range hood, a 6" duct should be sufficient, and instead of running it up, you can run it along the top of your cabinets, and out an exterior wall. You can also lower the profile by using 10"x3" rigid ducting which will fit inside the wall...If you have to run it up, you can either box it in and paint it the same color as the wall, or you can get a chimney hood....See MoreGas Dryer Vent
Comments (3)The periscoping vent would appear to address the issue, it looks thin enough to fit into a 2x4# wall. Ok, here's my question: I have an electric dryer and was considering using a second flapper type thing - a draft blocker in the line, it's a weighted door that opens when there's dryer air flow, and closes when there's not, to theoretically reduce heat loss/cold air intrusion. I noticed on extremely cold days there was frost round the pipe where it joined the outlet. I don't think it's correctly taped (they used duct tape not foil tape) and they've also used flexible corrogated aluminium ducting in parts, also a dust trap in part) which may have allowed for some moisture. They'd done away with an existing vinyl duct and run this one through the garage which does have the added benefit of a little heating of that space for free; but is this second door/flapper a good idea/permissible in most areas? I've attached a link. Whilst on the subject, what do people think of the covers or anti-vermin screens you can get for these things? I am pretty conscientious when it comes to maintenance, I imagine they could be hazardous when you use these things if you don't keep them clean. Here is a link that might be useful: Draft blocker...See MoreVenting a Dryer???
Comments (6)But if you can get to the attic, presumably you can get to the roof or to an eave/gable where you can properly vent the dryer to the outside. You can do it a couple ways. If you don't care about appearance, just get some round solid 4" duct and attach it to the back wall and go up through the ceiling into the attic and out the roof or an eave (using an elbow as necessary). If you want things to look really good, you would need to cut into the wall and run the duct there. The real challenge is that typical walls are only 3.5" thick on the inside because 2x4 studs are actually only 3.5" wide. Plus you would have to figure out a way to cut the top plate without creating structural problems. So, if that's too much and appearance is important, you could also build a box around the duct you install on the outside of the wall. You'll have a box, but that looks better than a duct....See MoreHood vent duct meets 2x4 in wall
Comments (4)There will be some repair work that will have to be done to the wall to run the duct work if you install a vented hood. Without too much more work the stud could probably be moved. A header would need to be installed to carry the load of the stud, just as would be done with any doorway or window. So I guess it comes down to what amount of work the vented hood is worth. I definitely agree that the downdraft would be better than the non-vented hood. The other thing to consider is the fact that adding 2 more 90 degree turns and the extra ducting is going to diminish the effectiveness of the fan. With that length you may need an in-line fan installed to boost the power. Your appliance provider should be able to help you figure out what you need for the amount of pipe you have.
