Hello!
I am new to the forum and have just become a homeowner. I have bought a house from 1949. The roof on the upper floor is a slanted roof and appears as follows from the inside: Masonite, air gap, and insulation directly against the rough boarding. Shouldn't the air gap be between the insulation and the rough boarding, or was this how they built back then? There doesn't seem to be any moisture or mold in either the insulation or visible on the rough boarding.
Thanks in advance for the answer!

Congratulations on the house. Yes, the air gap should be between the råspont and insulation. This should probably be changed during any possible renovation. But that's how it is with older houses... The air gap, as I understand it, is there so that when warm air meets cooler air, it can ventilate away the resulting moisture so it doesn't damage the råspont through mold growth.
