WUFI

Well, it's better than nothing but it just opens fid files. I don't do a film every time.
It's a pity you don't give us some free tool to read wufi1d.xml

Hi,

If we try to open a project with WUFI 5 without any licence, the software even doesn't permit either to see what we entered in it nor to see graphics.
Not allowing calculation ok but prohibit seeing what had been done, it is tough :/

Oh thank you, that's a very comprehensive answer !

OK I found THERMALAN ISO....

Hi everybody,

Is there some animal wool in the databases ?

Hi everybody, In some project, there's problem for vapor migration only on certain parts, for example when there is concrete in a timber frame wall. WUFI 2D can modelize that ? Is it possible to imagine a vapor retarder placed only at critical points ? What overlap width to prevent vapor to bypass t...

As I think about it, it would not hurt to see these recommendations appear somewhere in the charts...

Thank you, Christian ! Waiting for your answer :), I noticed that concrete humidity was determinant : with 2,5 % initial moisture, retarder is a bad option, with 8 % (typical construction level given by your database) retarder or nothing are both bad options, a variable Sd value (intello) is needed....

OMG, even, Christian Bludeau has no opinion ?!

OK, no help, I try in English :P I am astonished enough by the WUFI results for a concrete support for a timber frame construction (without vapour barrier film). Whereas a Glaser calculation announce a lot of condensation without the vapour barrier film, WUFI says exactly the opposite : the healthie...

Bonjour, Je tente mon explication en français, le sujet me paraissant complexe. Je m'essaierai à l'anglais si besoin :) J'ai un mur en ossature bois qui repose sur un support béton isolé par l'extérieur (avec un relevé d'étanchéité, j'ai utilisé la membrane V13). Ce support bénéficiera également de ...

OK, cool, no issue

Wow, thanks for this ultimate message very critical for me, I hope that Father Christmas will be generous with you.
Have a nice Christmas time and a happy new year too !

Hi Christma... Christian ! http://www.christmas-corner.com/images/christmas-smileys/santa_wink.gif you are on the right way, but what you are doing is to access the water content as a mean value over the whole mineral wool. The standard 4108 is talking about the formation of dew water at the contact...

Hi and hppy christmas to everybody, WUFI resumes criteria from DIN4108 which are about amount in moisture in kg/m². German standard DIN 4108-3 adds the following criteria : The amount of condensing moisture in roof or wall assemblies must not exceed a total of 1.0 kg/m². This is a more or less arbit...
