Hello everyone,
I have a question regarding our attic that I want to renovate for my son.
It is about the connection of a vapor barrier of the floor to the gable wall or eaves wall, where I am currently very unsure. The intermediate ceiling to the attic consists of wooden rafters that have been insulated with insulation between the rafters (so a very simple standard). The attic, which is still uninsulated (so a cold attic), was at least made walkable by me back then with a simple battens (tongue and groove) directly on the wooden rafters. There is a good distance of at least 60 mm between the battens and the insulation, so air could still circulate there so far. Now that I want to insulate the attic and convert it into a heated space, the question arises as to how I can make the wooden floor airtight. Of course, I can probably insulate the gable and eaves side as well as the roof well with insulation between the rafters and seal it airtight with a vapor barrier. But the floor area is causing me headaches. Should I simply attach a vapor barrier on top of the battens now? And connect it with the vapor barrier on the eaves side and the gable side? And then lay floor insulation boards on top of that? As I already mentioned, a radiator will be installed in the resulting living space. I urgently need good advice so that I can continue planning here.
Thank you very much in advance.
