First-world vs third-world (approximately).

In the first world, brick construction is extremely expensive and you're right -- modern residences are often built with structural beams (whether wood or steel), and the brick is usually just a veneer.

But in the third world, variants of brick (e.g. cinder block) are often the norm, and are structurally load-bearing, and work fine for two to three stories. And they're very easy and cheap to build with.

The US has a ton of cheap lumber so load-bearing wood frames are common. Many countries don't have forests like that so bricks/blocks are the way to go.

I have to disagree, and I don't think the first world vs. third world comparison is helpful.

Bricks are quite common in Europe, at least for buildings up to a certain height. The resulting buildings here (in Germany) offer higher living quality with better thermal and acoustic insulation than a typical North American beams + drywalls building. That's just an observation though and maybe the general construction method is not the cause - maybe it's just because our windows and doors are much more solid.

Bricks and stone provide abysmal thermal insulation. North American drywall with insulation is far, far better thermally. It's not even close.

Also... what does "much more solid" windows mean exactly? Like, are you saying European window glass is... thicker or something? Which wouldn't make any sense, and I'm not even sure what a benefit would be?

Tilt and turn windows, with triple or quadruple panes, low-E glass, and two gaskets for air sealing are much more common in Europe than in the US for residential construction, where they would only be seen in highly energy efficient high end construction.

They're also only seen in high end energy efficient construction in France, Spain, the Netherlands and I've never seen them in Eastern Europe. They're frickin' expensive! They may be more common than in the US, but still not "common".

Indeed. And double-paned windows are in the majority of homes in the US [1]. And triple-paned windows are a lot more expensive for not a ton more benefit no matter where you live.

Unless someone has some actual comparative statistics, the idea that European windows are somehow more "solid" than North American ones isn't at all obvious. I've spent years living on both continents and never noticed a huge difference. What matters the most is simply the age of and investment in the building, not which continent you're on.

Maybe triple-glazing is more rare, but at least in Poland, by my observation, almost everyone seems to have double-glazed, PVC-framed windows. I only ever see single-pane windows in really old and poor houses. IIRC, there was a rush of replacing old windows with double-glazed ones in the late 1990s/early 2000s.

> Bricks and stone provide abysmal thermal insulation

Even 80-90 years ago, brick housing in wester Europe was made with walls of two layers with an air/insulation cavity inbetween. Current practices usually don't use clay bricks but aerated concrete [1] which has great thermal insulation, plus insulation layers on top.

> what does "much more solid" windows mean exactly

Triple-glazed windows with well-insulated frames, rather than single-pane push-up windows that leak heat like a sieve. Massive difference in thermal and acoustic insulation.

Yeah, it’s not a 1st / 3rd world thing as much as a regional thing. Here in California wood is practically free, while stick and sheathing construction is the best way to build an earthquake resistant home. Other parts of the world have different concerns and costs.

Similarly, it's not common to build stick houses in Florida. Definitely regional.

Cinder block construction can also be difficult to insulate and hide services such as electricity and plumbing behind. In addition, brick buildings are a bad idea in areas subject to [seismic events](https://www.npr.org/2010/01/14/122547242/haitis-buildings-we...).

I was curious as to the cost of bricks so I did a bit of research...

A standard two-cell "cinder block" in the US weighs around 17.5kg and costs around $2.00 at home depot [1]. I suspect they'll be much cheaper in bulk. Maybe $1.50 if you buy thousands?

The same thing costs ₹65 INR in India [2]. Or about $0.89 (₹73 INR = $1 USD). Not sure if they would accept orders for a single block at that site.

So, more expensive in the US. But not extremely so.

I guess what is more expensive is to pay the builders in a first-world-nation, since brick-laying is labour-intensive and requires skill.
Re:Kenyan recycles plastic waste into bricks stronger than c... by djrogers on Wednesday February 10, 2021 @07:58PM (#26096929)
Stick building homes is labor intensive and requires a skill as well…
Re:Kenyan recycles plastic waste into bricks stronger than c... by crazygringo on Thursday February 11, 2021 @02:00PM (#26105670)
Obviously it's the difference between the two.

Bricklaying requires much more labor than wooden frame construction. And it requires more skill which most contractors do not have.

It's more expensive for these basic economic reasons.

I was under the impression they used metal to reinforce masonry, but apparently not all everyone does. Found an article that goes into more details and lists pros and cons of the masonry approach here:
