>>1013568Jesus, please don't turn this into some US vs. EU thing. I'm European myself but this kind of attributing something you don't like to people of a country because "hurr dur I've seen an American do this on youtube so I guess they all do like this" is just childish and the reason why you rarely see any real discussions on /pol/, /b/ or /k/ or whatever.
FFS lots of people make these walls, not just Americans.
>>1013590Anything warm will radiate heat waves. Just like a clear, stary night is colder than an overclouded one the wall helps to reflect heat that would otherwise have been lost. Even though wood doens't reflect as well, it absorbs the heat and thus warms up, radiating heat back, minus the loss that happens to the wind or is radiated to otherdirections.
Besides, it also blocks the wind and finally it makes the smoke more likely to flow towars the wall and up, because of the way the warm gases will rise and thus drag in new air from the sides. This air cannot (as much) come from the direction of the wall as from other directions leading to a chimney effect.
