Building Codes require so much fire resistance and sheet-rock (asbestos was even better) is the cheapest/ best option. Also walls aren't water tight so anything will mold when water sits in dark cool spaces.

I have helped people in Katrina and Bogalusa that wouldn't let us remove the wood paneling in some locations in their homes but that is a terrible idea because the insulation behind the wood and the wood inside the wall will mold this can be very bad for your health, you can't always see it but it's there and growing.

Pre-cast and poured-in-place concrete walls are always an option.

Yep. I spent 5hrs pulling that shite out with scrapers in someone's house today. That picture of the all-wood interior looks like the 7th level of hell to me.

We didn't flood, but water cane 1/2 way up our slab. I told my wife I was going to build a cinder block retaining wall around my property if we had gotten water. After helping friends all week I hope I never have to do that shite again.

If it's nailed down its no big deal. The glued stuff is terrible.

Walls were frequently covered in cheesecloth and paper over shiplap boards or were plastered. Plaster walls are more similar to Sheetrock without the weight or expense. They are also much more difficult to repair once damaged.

Sheetrock is the cheap route that also provides a fire rating.

Wouldn't all that wood warp and be ruined by a flood too?


My grandparents have a house in Chauvin that flooded twice. Cypress ship lap through out. None of it was changed, still no mold.

We use sheet rock because it is cheap and fireproof. I have heard old firefighters tell me that there is no comparison as to how fast a home Brunson today versus a home from 60 pr 70 years ago.

My biggest problem with drywall is the flip side of the coin of it being "easy" to repair (although I'd submit that to replace and match texture can be tricky for the DIYer).....it's so damn easy to damage.

It is abundant, cheap, fire resistant, has good sound insulation properties, is easily repaired, easily painted, and even offers some R value.

A couple drinking buddies who are old firefighters tell me they deal with far fewer home fires today, but when they do the fires are tougher to put out because of all the plastics and chemicals in the home.

Instead of just doing like a Luan, beaded board, or ship lap in homes?
In our climat, these products will also mold.

Most concrete walls have sheet-rock with nailing boards between the sheet-rock and the concrete so you would have the same issue. The other problem with concrete is where do you run your electrical wire and how do you put in receptacles so they don't stick out past the wall surface? It's hard enough in a wood framed house to run a speaker wire or add an outlet after it's built, forget it with concrete walls.

Cheap, easily repairable, easy to alter the appearance and it doesn't burn easily like say ....WOOD

Post build changes are a problem still, but most concrete wall builds I have seen aren't solid concrete: they are poured in syrofoam molds.

So when you do your wiring, you are running through the foam, which also provides the a lot of the indentation so electrical boxes don't stick out.

Costs, however, if beaded board or wood paneling is used - it would still have to be removed to get at the wet insulation.
