Great, that's the one! Thanks! Just not much information on the website. I actually can't find any information at all... :x

For those who are interested, I found some information here in Danish: http://www.nordisknhl.dk/baggrund/nyhedsrum/ny-diffusionsaaben-isoleringsloesning.aspx

Not a lot of information about this... :x

If you want diffusion-open insulation on the inside of the basement wall, open-cell polyurethane might be an option, which is sprayed directly onto the wall.

Someone here on the forum was recommended to spray closed-cell polyurethane on the inside of the basement wall. I thought it seemed a bit doubtful, but I recall that he got this recommendation from two different companies, one of which I hired to insulate my roof, and I am very satisfied with it, and I thought they were good too.

Closed cell sounds strange, but I guess open-cell could be equivalent to what I'm looking for.

Also read the article in GDS and became curious until I saw the price, 600kr/sqm...

Fortunately, I don't need that many square meters, so it should probably be okay. I have been in contact with the retailer, and they plan to introduce it to the Swedish market at the beginning of 2014.

GDS is basically a Danish newspaper. But the point of insulating on the outside is that the heat from the inside will help to dry out the basement wall. If you insulate the inside, you also move the "cold boundary" further into the wall viewed from the outside, and the moisture remains in the wall if you're unlucky.

In the latest issue, they showcase a project where they use Ytongs Multipor to insulate the inside of a wall. Seems to be a similar product.
