To Heesu...

First, the insulation properties of wooden houses are high ????...
They do fill wooden houses with insulation...
But since it is filled between the wooden pillars...
The wood itself has poor insulation... in other words, the wooden pillars themselves are not insulated...
There are hundreds or thousands of wooden pillars in the exterior walls...
This is the cause of condensation in winter... it means it's not insulated...
And wood is vulnerable to moisture...
Second, wood is several times more expensive than other materials...
The labor costs for wooden buildings are also several times higher... and the construction costs are several times higher...
Naturally, remodeling costs would be expensive too, right..?
Don't act like you know something when you don't know jack shit..
