Inside out walls in small sections?

How thick should my walls be, should I float my floors (and if so, how), why is two leaf mass-air-mass design important, etc.

Inside out walls in small sections?

Post by SunkenCity »

Has anyone ever had success building a inside out inner leaf wall in small sections, as in smaller than building the whole wall and then raising it into position?

obviously it would have more seams in the drywall sections to seal and would require more materials(2x4's, sealant and chosen method of attaching hardware) but it seems like it would be safer than trying to raise large sections of wall that have layers of drywall attached.

I'm thinking pieces that two people could lift into place with drywall overlapping in certain spots.

Can anyone see why the added 2x4's would be a problem?

If anything it would strengthen the wall, right?

Hey Sunken city,

I would think two people could lift a smaller wall section. I did it by myself with a forkilift. Only to get it about 45 degrees and then pushing it vertically by hand.

or you can purchase or rent a wall jack

It would be added mass, so outside of the potential leak areas were the the multiple partitions connect together and the potential wall assembly weakness if you do not bolt these pieces together, do it.

I've looked at your build before you did a great job!

What I'm trying to build shares similarities but the existing structure on my build inhibits me quite a bit. Can't get a forklift in here and I don't think there's quite enough space to be able to construct the whole wall(12ft ceiling but 13ft of floor) on the floor and then raise it.

All those wall jack videos are always 8ft walls never seen them do anything higher lol.

Was definitely thinking thru bolts connecting everything and do some precision cuts on a table saw to make sure all the drywall pieces fit perfectly. Maybe angled cuts on the drywall so they lock together? Sort of like pre-assembled building blocks of studs (16 on ctr), drywalled x2, greenglue and sealed.
