I will never understand why we fill our walls with mechanical and electrical infrastructure and then wrap them in a paper and plaster, which then needs to be torn, broken, and repaired in order to maintain said infrastructure. Pipes will fail. Wires will fail. Ducts will fail. Maybe not in 5 years, but over the span of 20, they will. Why make them so frustratingly inaccessible?

The paper is a critical technological innovation. It shrinks upon drying, turning the sheet into a prestressed panel. Predecessor manufactured wall materials like Beaverboard are much flimsier because they lack a taught skin that enhances rigidity.

it's pretty cool how the paper faces effectively provide all the strength by creating a torsion box w/ the gypsum in the middle.

As a German I always found North American houses and their drywall and wood constructions incredibly odd. It always felt flimsy to me. From my experience we just started using drywall for some interior walls on some newly built homes. But throughout my life I was used to very massive walls.

I suspect the prevalence of "flimsy" wood and drywall constructions to be part of the reason why Americans dislike apartment living. They provide little sound insulation, are prone to water damage, have a shorter lifespan than the average person and once they catch fire they burn the entire thing down.

Concrete or brick buildings are much nicer to live in, but expensive, so they are not very common among new constructions.

The way houses are built and what materials are used is very location specific do to climate and economics. North America has oodles of land to grow wood on. When you have cheap nails and screws wood is a FANTASTIC material to make houses out of and not flimsy at all when designed correctly. Europe used to make houses out of wood until they cut down all of their forests. Wood and drywall construction has the advantage of being fast to build and easy to remodel.

I personally like houses that use Insulated Concrete Forms for the exterior walls.

Earlier quoted context omitted.

The trick is to have 100 years of landlord special paint holding it together

And with the old lead paint lowering your mental capacity as the years go by, you care even less about small inconstencies

Safely contained behind several tenants worth of turnover or so I'm told. Walls are skip trowelled so inconsistency is just how they are.

A huge share of the gypsum used in drywall is *synthetic gypsum* — a byproduct of flue-gas desulfurization (FGD) at coal-fired power plants. When SO₂ is scrubbed from exhaust using limestone, the reaction produces calcium sulfate dihydrate, chemically identical to mined gypsum. In the US, FGD gypsum has accounted for roughly half of all gypsum consumed by the wallboard industry at its peak. The "cheap, uniform, and f…

I used to work for a drywall manufacturer who still owned their own mines despite efforts to divest from them by some. They always viewed it as a structural advantage to still own them and not be wholly dependent on the coal plants (which effectively have conveyor belts going from the coal plants to the wallboard plants). I imagine as time goes on it'll become even more of an advantage for them to still own those mines as their competitors are forced to buy at highly inflated prices (or even from them) as coal shuts down.

Drywall gets maligned, but it is a pretty remarkable building material. Inexpensive, easy to fix/finish, and very fire-resistant, especially for its weight.

The timber-stud and drywall model also works well for the modern world, where layout preferences and in-wall technology changes often. It was only about 20-25 years ago where having POTS lines/jacks in multiple rooms was cool, and now they're mostly useless.

I live in rock and rolling California, and we love our stick framed houses. They’re very resilient to the tremblors that plague us.

Yea, if we’re hit hard enough, the stucco may or drywall may crack, but, big picture, those are cheap cosmetic fixes compared to anything more structural being damaged.

Back during the Northridge quake, my friend was buying a second floor condo in Santa Monica (which was hit pretty hard). It resulted in several drywall cracks, but nothing worse than that. Even better, the closing day was scheduled for the day after the quake.

As a German I have to admit we are culturally odd with this. Our houses are way too over constructed and the dry-wall stigma here is just one aspect of it, wood construction stigma is another. It thus is no wonder that Americans have way more affordable housing.

Those stigmas are also odd for most of our heritage-like old towns that are full of still-intact "Fachwerk"-Wooden-Constructions - which basically use the same technique, should give us a hint or two. Also wooden constructions do allow to comply with our ever climbing ecology standards, without complicated venting mechanisms to keep mold out (as you need for stone). Those two stigmas are also odd, given, that drywall and wooden construction sectors are actually huge in Germany. Knauf is one of the worlds largest companies in the wallboard sector.

For a while in the 90s, a friend from Canada went to Germany and started building NA style houses (wood frame, drywall) in Germany. People loved that it could be finished in 3 months instead of 9-12 and cost 1/3 less, IIRC.
