Durability prefabricated wooden house wall

There may also be prefabricated house manufacturers who are not represented in model house parks. But somewhere there will surely be at least one model house. Especially with a prefabricated house, I would rely on large established companies that have a lot of experience. I feel similarly about the topic of heat pumps. I probably wouldn't choose a heating engineer who primarily installs gas systems and has only occasionally installed a heat pump so far. I would prefer a company for whom heat pumps are the daily business.
