Well done! What is the function of the black layer? Protection of the insulation against moisture from the room below?

Hi. Its for protection aginst warm air/moist from the room below. It let it pass but makes the moisture to slow down. Its instead of plastic wich they use in modern homes.

What is the swedish name of the product?

Its name is Vindpapp AC 350. Usually you use it behind the panel on the house.
