Can I use a wood top plate on top of a steel track to build a roof-bearing steel frame?
We design from the top down and build from the bottom up. I’ve learned that staying with “standard building techniques” in both the design and construction phases will save time and money.
We design custom homes and when we use a product that’s never been shipped west of the Mississippi, then we’ll pay extra for that particular product and pay extra for the labor to prep and install, because the local contractors are not familiar with that product.
Likewise, if we design a 12’ diameter curved wall in the house, we’d better have a good reason, because that wall will cost extra.
Likewise, if you design a composite wall construction detail, you’d better have a good reason because you’re going to pay extra.
Standard building practices tend to use either steel or wood, but not combined because they are not familiar to 1) codes review technicians, 2) building inspectors, 3) sub-contractors who will need to adjust their products to fit the new technique, and 4) General Contractors who will need to coordinate scheduling, miscellaneous materials to finish installations, etc.
There are some issues with your assumptions. Steel construction does NOT make rooms more or less soundproof. (Staggered stud construction, double wall construction, types of materials used on and in the wall, etc. all help with sound control.) Steel construction (non-combustible construction) is for better fire resistance, not better soundproofing.
Summary:
There’s a reason that you’re not finding “typical” construction “details” (as you call it) because it’s not done often or frequently. Mixing construction systems will increase costs and may eliminate some contractors from participating.
