The "cheap, uniform, and free of defects" story is partly a story about coal. The drywall industry scaled on the back of an abundant, nearly free waste stream from the energy sector. It's a classic example of industrial symbiosis — one industry's pollution abatement becomes another's feedstock.
And it cuts the other way now: as coal plants shut down across Europe and North America, synthetic gypsum supply is shrinking. The drywall industry is facing a real raw material squeeze, with manufacturers having to shift back toward mined gypsum or find alternative sources. There's ongoing work on using phosphogypsum (from fertilizer production) but that comes with its own radioactivity concerns.
For someone in your position this is particularly relevant — the "wonder" of drywall is entangled with the fossil fuel economy in a way that makes earth-based construction methods look increasingly attractive as that supply chain unwinds.
2) Why emphasize asbestos when talking about plaster? My understanding is you likely have more to worry about if you have a house from say the 40s-70s, which almost universally have some sort of drywall product.
In my humble opinion, they are significantly better than pounding a nail into drywall. Of course, I also have an absurdly large collection of framed photographs and other art, all of varying sizes, and I love swapping frames around throughout my home. Having picture rails throughout my house means I don't have to keep pounding holes in the wall every time I replace that 20x20" photograph of my toddler shot in a square aspect ratio with a 16x20 shot on my 4x5, or whatever.
This is way better than arguing with partner about the proper height, making a destructive hole, then having to cover/patch when opinions or artwork change. My walls are not drywall, so that was a big factor, but the freedom to arrange/rearrange is a major benefit.
it is a bitch and a half for hanging anything (just like plaster on lath), plus it screws up wifi.
Pro tip for finding a stud, if you have access to the bare floor -- stick a drywalling knife / spatula under the bottom trim and poke. you can find the studs that way, and then measure off since 16" is pretty common. Measuring off the edge of an electrical box can work too, but you have to figure out what side of the stud the box is on...
The trick for this is to just find the stud. Same thing you'd have to do in drywall. For light stuff like photos, you can get away with putting a nail right into the lathe without having to find a stud. If you miss the lathe (you can tell) just move the nail up a half inch.
> a method of constructing walls that has been a mainstay for at least 6,000 years, predating mud bricks
To be fair the article is about drywall and its history, not the history of all walls in general.
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?
I have seen another method for making walls that were accessible though, from a homesteader/ hand tool woodworker and carpenter. His walls were 24” thick with huge areas for piping and electrical and had 4x4’ removable wood panels.
And then you have to match the surrounding paint, which is all but impossible since even if you have the same color, the original will have likely faded over the years, making your newly applied coat a mismatch, so now you have to paint the entire wall (no fun when it's a big wall). And if you had wallpaper instead of paint, good luck to you unless you saved some extra scraps.
All in all, an access panel would make the job much simpler.
Drywall is not too bad to deal with. And 99% of the wall surface doesn't need to be opened for a -long- time.
Drywall is manageable and cheap, I agree. But it's more painful than it should be for something that _will_ require maintenance.
Personally I've been printing snap in access panels whenever I have to get into a wall these days - in white PETG they pretty much disappear into the wall for me.
In addition to being much more attractive than exposed infrastructure, drywall and the insulation that gets put behind it help make your house much more energy efficient.
I've patched quite a bit of drywall, and I'm about mediocre at it. But it seems so silly and unnecessary to me.
Everything else in this world that requires maintenance comes with access panels and other means of easy access. In our living spaces, some of which should ideally last tens of years (mine is from the 1890s), we seal it all away.
Conduit all the things and paint to match?
In the UK it used to be common for pipework to be exposed and painted. Electrical conduit is pretty common in "industrial" places like garages but the number of sockets people expect now would mean you'd barely have a flat wall anywhere.
The current preference is definitely for clean looking, square rooms. When pipes don't fit in the walls themselves, like soil pipes or around boilers, they are boxed in or hidden away in a cupboard.
> Some buildings standing today still have wattle-and-daub panels from 700 years ago.
Will any drywalled building survive even a tenth of this time?
> The plaster mixture used then was a homegrown concoction, with recipes matching the climate needs and vernacular material availability.
The wonder of wattle-and-daub (clay) and plaster-and-lath (lime) is that the materials are breathable, move with the structure, and can even self-repair small cracks. I don't know of any old house that suffers from black mold...
My last big gripe with gypsum drywall is disposal. Demolish a property with clay or lime walls, and they'll naturally degrade into the environment. Drywall needs proper disposal: "Do not burn: Drywall releases toxic fumes. Do not bury: It can create dangerous hydrogen sulfide gas in landfill."
Does anyone want to live with that?
