we in a villa....

[Totte_C]

The new issue of "Vi i Villa" just arrived. Since we're going to renovate our basement, I became really interested when a carpenter converted his basement garage into a room.

Imagine my surprise when I read:

"When the inside of the exterior basement wall is built up, make sure to fill the space with insulation so that there's no air gap where condensation could form."

Does that mean the insulation should be placed directly against the cold exterior wall? I always thought it was advantageous to have an air gap and "platon" as a guarantee against moisture and the like.

In our basement, I have underfloor heating. I had planned to put platon on the inside of the exterior wall followed by a framework with insulation, chipboard, drywall...

Does this seem sensible, or should I do as the carpenter in "Vi i Villa" suggests? I'm just an academic/salesperson trying to amateur DIY in my spare time... (Meaning I don't really understand much...)

Any comments?

Yes, that sounds a bit... different.

To refrain from underfloor heating just because you can't fit 250mm insulation is just as silly.

Mmmmm... I thought about that too, but some people think it's nice with rag rugs on ceramic floors, so...

But shouldn't carpenters know or? You don't do shoddy work at home, right?

"When building up the inside of the outer basement wall, make sure to fill the space with insulation so that there is no air gap where condensation can form."

That carpenter probably thought that moisture can't condense inside the insulation??????

Perhaps there is a difference between condensation and "disktrase-fuktig" insulation?
