Insulation in fast house construction

Hello everyone, I am worried about my house construction, We started building a month ago and now the shell is almost finished. Next week the roof truss is supposed to come. The house is being built with 24 cm Poroton T12 masonry. Today I learned from the head of the construction company that they want to complete the house so that it is ready to move in by December, including insulation. The insulation is supposed to be 12 cm thick mineral wool. I am worried whether this is all happening too fast because it has rained heavily in the last few days and the masonry has also gotten quite wet in some places. What should I pay attention to now if the house is finished so quickly, should I wait to move in and let the house air out for a few months with the windows open so it can dry or does anyone have other advice for me? PS. we will have a gas boiler with underfloor heating, no ventilation system Best regards Lukas

So I think you should trust your gut feeling; if it says the walls are dry enough for the insulation, then that's probably the case. And even if not, opening your windows will probably help little, especially since there is also a lot of humidity outside in autumn.

I think the experience of the site manager is decisive here as well. I would also trust him, because they are not doing this for the first time. Actually, it's good that the construction is finished so quickly.

Today, fast construction is also a matter of money. In the past, construction was stopped during winter, allowing the shell to dry out well. Today, the building is occupied immediately after completion to save on rent. I would set up a [Bautrockner] here and ventilate everything well.

Be sure to let it dry out here. Just moving in after construction will cause problems. Especially with high humidity, this is toxic for the insulation. Ventilation won't help much; it's better to use a [Bautrockner].

If you trust the site manager, you can rely on him. I would take it easy and let the house dry. Rushing won't help here.
