I have a storage room under an extension that I'm soon going to start addressing. Half is made of leca and the other half with normal studs with asphalt board and wood paneling. This is insulated and what I'm wondering is if I should put plastic or something on the inside before I start covering the walls?
No one?
Well, that's just it... I've prepared to connect the radiator to the geothermal heat but I don't know if I will do it. If I do, it won't be more than minimal heat. But I also don't want it to get damp... I'm going to use it as a storage/workshop type...
And yes, it is mineral wool as insulation in half of the space's walls. The other half is leca, which will most likely remain uninsulated. So what do you say, should I go with plastic or not? Or something else?
Ceiling will become plasterboard. Living room covered with windproof fabric before insulation. Older garage floor slab used as the floor, uninsulated. Planning to install vents for ventilation/airflow. On the walls, I will have plasterboard with rough-cut timber behind on one wall and possibly plywood on the other since not much will be hung on that wall. Just a tool board and some shelf. Will it manage without plastic or will there be moisture that damages the rough-cut timber?
The raw board will probably be fine. The risk with constructions without plastic and mineral wool is that if there is positive pressure in the space and warm, humid air starts to escape, the moisture will precipitate as condensation when the temperature drops. You then risk moisture/mold on organic material (mineral wool normally does not mold) in the construction. However, in spaces that are not permanently heated, plastic is not recommended because the phenomenon can become the opposite.
Feels like the insulation is a bit damp in some places... But I'll go with råspont plus drywall on the walls then.
