well this is mostly for house-size buildings everything else is concrete(with rebar that will rust through in 100 years). At least in totilitarian countries here in the north its illegal to build a house that doesnt meet ridiculous energy efficiency standards which is pretty much impossible without going for the wood frame type. EVERYTHING built will be of this type and have the same moisture problems because the advanced ventilation doesnt work as in the lab and normal people dont know how to maintain it

they do not trust to their nails to hold the floor joints together during earthquake or strong winds.

therefore hacking their own technology by reinforcing everything with some steel plates and more nails, which is ridiculous.

Wooden houses here are an attraction and considered luxury (proper wood houses, not wood framed + drywall). Everything here is reinforced concrete + red aired bricks even some skyscrapers. If isolated its rock wool, never foam.

Prestressed is always reinforced and is stronger than on site pour I assume? Its rarer in civil eng, more in big projects

All commie blocs are using concrete roofs. Think like 70 years old already with 0 issues.

I believe that they can last forever and need little to zero maintenance if you put the insulation outside (on top of them). They will also provide great thermal mass and balance the climate inside even better.

About the cost it depends. If you use some very low grade wood and you do not care about having a decent mansard or something, it will be probably a lot cheaper with wood.

But if you put some superb quality wood in it, the price will be the almost same, because concrete itself is not very expensive but it's heavy and this will reflect in the whole construction of the building resulting in thicker supporting columns (more rebar) and more money and effort put into sloped slab on the roof.

>All commie blocs are using concrete roofs.

Commie blocks use mostly flat roof with gravel on top + drainage system like skyscrapers have and it works pretty well for its age. Concrete roof is mostly on some civil houses, but wood roof is more common on regular civil houses that use RC framing and red brick (or a combo of RC and wood beams for roof).

Im wondering why there isnt more RC roofs, wooden roofs need to be replaced at least every 50 years since allmost good wood is exported and became expensive.

can you expand on that? Wont the big thermal mass of RC roof heat the house too much in summer? Unless you put terracota tiles on it? Local summer houses in Croatia work fantastic with that combo but I dont understand the mechanism of temperature regulation

Most of it.

>>1510992
>Why is RC framing so rare in USA?

I believe that it's about the speed of building.

With RC when you're poring a columns and slab for example you will have to wait about 20 days before you can continue working on the next level. Then when you finish the structure and put the brick walls you need to put stucco on almost every surface. Then again wait about 6 to 10 months for everything to dry.

The average home in Europe is being build in about 2-3 years or so which is way too long for the American standards.

It is labor intensive, dirty and slow.

>> No.1511016

>>1511011
>Commie blocks use mostly flat roof with gravel on top

The principle is the same.

The only difference is that one of them is sloped and covered in tiles and the other is flat (or actually very slightly sloped).

Greeks are using extensively concrete roofs. pic related.

If you put the insulation outside the roof the summer heat (or winter cold) won't make any difference. Your home will stay cool and comfy.

dirty - yes, but far less labour intensive and way faster than 2x4 framed houses. Very cheap also. You can build it with a help of a few mates and a rented cement truck within half a year.

>stucco

you dont need it, red brick is very resistant to rain, its mostly for aesthetics or to cover the rock wool. If you want you can build the outers with "facade brick"

>>1511019

houses in Dalmatia only have terracota tiles on concrete roofs and it works as a charm. How do you think that method would work in colder climates? You can always add rock wool later from the inside.

It will be better than wood, because it's air tight and will provide great thermal mass for smooth internal climate even when your heating is off.

The idea is to put the wool outside in order to protect your slab form heating or cooling.

I understand your logic, but that sounds like a recipe for mold in insulation. It would swole up and might mess up the tiles...? Ive never seen such method used.

You're making ventilated roof. That's why you are using wool because it's vapor preamble. Between the wool and the tiles you need also to put vapor preamble water barer membrane.

It's common approach. And maybe the best out there.

I dont trust those "water membranes", Tyvek and other plastic they put on houses. Its all shit that will melt away...its has its place for certain application but longterm thinking - high temperatures or some combo of elements will affect it eventually.

Similar to GoreTEX, its super waterproof and breatheable in shoes, but after 5 years it totally changes its effectiveness unlike the more traditional materials like waxed leather...

It's so frustrating, that I'm considering to start drying my wood by myself or something..
