Hello, I live in a single-story detached house built in 2005 that has an unused attic space. I have now laid down floorboards (chipboard) in the middle section of the trusses about 3 meters wide without any form of moisture barrier between the roof insulation and the boards. For the moment, it will remain like that, but the idea is to eventually also install insulated walls and ceiling for the space and maintain above-freezing temperatures all year round, not using it as living space but solely for storage. So what I'm wondering now is do I need to install a moisture barrier in some way and where?
Hi Lokke, welcome to the Bygga Hus forum!
Interesting question!
If you insulate the space around it and don't add any heat, it will take on the ambient temperature.
So how do you plan to raise the temperature to above freezing?
It will surely get some heat through the flooring from the lower floor.
But the flooring there is quite well insulated, right?

With only the information you provide, I would say no. The space is not subjected to any more moisture than the surroundings, i.e., the attic. However, a cold attic is not intended for warm spaces, which means you may still experience moisture problems.
Thank you for the response. What I was primarily worried about was whether the panels covering my part of the ceiling somehow block the ventilation of the insulation. I will probably heat the space with a regular heater if needed.
