I installed insulation (170mm) in our extension 1 week ago to allow the structure to dry out a bit more before I add the vapor barrier, having used heaters and dehumidifiers. Today, I discovered that there was condensation inside the wind barrier and that the insulation closest to it was slightly damp. I have vertical paneling with sparse boarding and wind barrier outside of the insulation/frame.
My question is whether the condensation will dry outwards through the wind barrier, or if I should remove the insulation?

Just removed the insulation and letting it dry for a few days, how quickly does insulation dry if it only has a little moisture on the surface? (using construction fans and dehumidifiers)
The mistake you made is that you did not install the vapor barrier directly. As it is now, the moist indoor air condenses on the wind barrier.
A problem you can easily encounter if you build during the cold season.
Take down the insulation in the part you can and spread it out on the floor. Use construction heaters as you are doing until it is dry on the wind barrier.
Then quickly install the insulation and immediately apply the vapor barrier. The remaining moisture will be vented out through the wind barrier. The important thing is that it is sealed inward so that no additional moisture gets into the insulation.
