I got an email this morning from one of our readers, Kevin, of CozyHomePlans.com.
Lots of folks think about using metal studs for the construction of tiny houses because of the weight advantages.
Although it’s becoming well-known that the screws can come loose when you tow your tiny house due to the vibration.
So there are some disadvantages to consider, as we’ve learned, and Kevin does a good job of summing it up for us.
Here it is for those of you who are interested in this issue.
Thanks Kevin! I’m passing it over to him:
Was catching up on THT this morning and saw the discussion on metal studs. Here is my comment but I was not sure if this was the right location for it. Is Dan is using metal or not? Just wanted to get your opinion first.
I am certainly not an expert with using metal studs. In my limited experience they would definitely not be my first choice, especially for the beginner builder of a tiny house. The metal structure is actually kind of flimsy, the sheathing “typically drywall” becomes an integral part of its stabilization during the whole building process. Unless you plan on using large pieces of wood for the interior/exterior siding, there will be no stabilizing core to hold the metal studs together. I have only used and seen metal studs in non load bearing applications, so look into using heavier gauge material for the overall frame. Fine thread screws will hold any material to a metal stud, but extra pressure needs to be applied because these are not self-tapping screws. Then you will have aesthetic issue of screw heads to deal with both inside and out. Another question would be in the insulating of the home. Due to the shape of the metal studs having a hollow center, additional consideration needs to be taken in the framing and filling of this cavity. All electrical should be run in flex conduit or at the minimum be shielded from the metal when running through and along the walls. This is a much more expensive and difficult way to run electricity, even in a tiny house. Do your homework because the expense and liability could easily outweigh the weight of wood.
