Replacement of insulation after fire with water damage?

Hello everyone,

There was a fire in our new building. A water pipe burst and flooded the entire house half a meter deep :mad:
It penetrated through the walls and came out again from the exterior brick joints. Quite a disaster. Now the question is whether the insulation needs to be completely removed or if I can leave it in and let it dry? Drying would of course be cheaper, but I just don't know how to do it.
My house is a timber frame prefabricated house, the exterior insulation consists of "water-repellent" Rockwool "Fixrock VS".

Hello Berthold, I would be more concerned about the moisture penetration of the wooden components. The mineral wool does not absorb water, especially the water-repellent version would be rather unproblematic in this regard. If there is still water/moisture in the wall structure, which I assume, it is, as mentioned, dangerous for the wooden construction. Drying should definitely be carried out by a professional company, also because of the warranty. Have you already spoken with the insurance; would the opening of the wall (in order to dry it properly) be covered by the insurance benefits?

That is a nightmare for every homeowner. The restoration after an extreme water damage must be carried out by a specialist company. The wall must also be opened up, otherwise, it is all worthless.

That is also a sensitive topic and an expensive matter. I just hope the damage is covered by the insurance. The wall has to be opened up and then everything dried out gradually. A professional company also has the appropriate machines.

This is a difficult procedure and first check if the insurance covers the damage. In the case of such a large water damage, it is advisable to replace the entire insulation in this area. In my eyes, drying helps little.

It is important that the wooden components have not gotten wet. The wall must be opened here and a specialist company will begin the drying process.
