ᐅ Interior insulation with udiin, experiences

I have a Poroton exterior wall without insulation and would like to insulate it from the inside using Udiin. However, I am concerned about the risk of mold growth behind the insulation. Are there any experiences or insights on this?

I can’t offer any personal experience with this product, but basically, internal insulation can work with almost any insulation material. You just need to keep in mind that the dew point will generally shift to the inside surface of the wall, so a vapor retarder should be used, and it’s crucial to ensure that it is properly installed and sealed.

Is there a particular reason for your choice? I find that stuff relatively expensive.

External insulation is unfortunately not an option for us, as our house is already quite dark inside and it would make this even worse. Internal insulation was an alternative, and the material used is natural. However, I cannot find any experiences or feedback about this.

Why should that need reinforcing? You can also use reveals around window areas.
Interior insulation is always problematic and should only be considered for a listed facade.

Because the insulation, about 14 cm (5.5 inches) thick, pushes the windows further inward, resulting in less natural light entering.

That's why I write vouten; that way, you don’t have that problem.
