It is difficult to build a good house using steel frames.

A friend sent me this photo today. About two years ago, he built a house out of steel.
We receive consultations from people who say, "It's so cold, please do something about it."
In such a house, by chance, the wife forgot to turn off the heating last night, and in the morning, the exterior wall
It seems that it was in such a state.
Most people make the mistake of thinking that the exterior walls have insulation in them.
It will get colder and the steel frame will get warmer.
If you think about it rationally, it's obvious, but the insulation makes it difficult for the warmth inside to reach the outside.
The steel frame allows the heat inside to easily escape to the outside.
As a result, condensation occurs only in the areas where insulation is present. This is the photo.
You can instantly tell where the insulation defects are without using a thermograph.
Even though I haven't designed any of the properties myself, I've had the experience of thinking, "It's a new building, but it's so cold, I can't do anything about it."
I have been approached on several occasions with the following request: "It's not working, so please do something about it."
Most of them are steel frame houses.
There were some households that ended up like this, despite saying, "I'll do it."
Most modern houses have their structure covered from the outside, so it is not easy to make a wooden house.
It is impossible to tell if it is a steel-framed structure. However, if you look at the north elevation in winter, you can tell.
This is often the case. This is often how it goes.
In this case, the exterior wall is made of galvalume steel, so it is smooth.
This is unlikely, but in the case of a deteriorated sprayed exterior wall, this type of condensation can occur.
As this process is repeated, a clear, formulaic pattern will become established.
In cases other than those in fire prevention areas with narrow 3-story buildings, it is rational to build a house with a steel frame.
No matter how I think about it, I can't think of a reason why.
Aside from the fact that businesses make money...
