Well, I don't know where you're based in the world, but must be in a warm area.
When I see people building houses in tv, especially in the US, using those materials, it creeps me out as those houses would never stand a chance here. For me a house means built of bricks. You need heating here, which can only be effective if you have a proper house :)
So I understand your concern. -20C is not always fun 😂
