Our two-story timber frame house recently had its insulation installed. Ironically, it rained heavily during and after the work on the upper floor ceiling. A significant amount of water has collected beneath the insulation in the vapor barrier. The glass wool above feels really wet. Now I’m worried that mold might develop. Can glass wool mold, and will everything dry out on its own?

I recently read that glass wool insulation almost completely loses its insulating effect when wet. Perhaps an expert can confirm this...

Would it help to peel back the vapor barrier to let the material dry?

Wet glass wool is faulty and should be replaced, as it will be very difficult to properly dry the insulation mats.

In the meantime, I tried to dry the glass wool mats, but it didn’t work. By now, everything has been replaced.

Did you replace it yourself? It is possible to dry the insulation again using machines.
