How to handle when former exterior wall becomes interior wall?
Hello everyone,
I am going to build an extension on the house soon, which means that a current exterior wall will become half interior wall and half exterior wall.
How should I handle the part that will become an interior wall, i.e., how much should be removed to turn it into an interior wall with gypsum board, or can I leave everything (paneling, etc.) as is...??
The exterior wall looks like this today:
built in 1939 with the technology of that time, additionally insulated in 2001 with 45mm uni board, 'wind barrier', air gap, studs with cover strips.

It doesn't matter as long as the wall is dry, the difference is that you get less floor space, but sometimes it can be nice if there's an opening to have a deep reveal.eTiger said:
However, with the image I have of your question, I would, as JanneL wrote, remove as much as possible since it doesn't serve any purpose. Except for aesthetic reasons then.
We have such a wall too and we've done exactly as JanneL suggested. The old exterior wall with panel is still there, but we have removed the battens. We will put plasterboard on part of it, and part of it we will probably keep the wood panel visible.
Those old walls from the 1930s are built of wood, wind paper, and sawdust, so there should be no problem at all having them as interior walls just as they are. Ours aren't particularly thick either, compared to modern wall constructions, so there's no reason to remove parts of the wall because of that either.

Well, if the house were mine, I would be interested in seeing what it looks like under the additional insulation. Is it sound under the additional insulation, or did they just cover up any potential damage that might have existed? (I've seen examples of this myself). Does the wall look like pinebar describes, or is it made of tongued two-inch planks?eTiger said:
Yes, it must be sealed tightly as well. Before we added our additional insulation on the outside and new facade panel, rainwater would find its way into the house through the gaps in the old facade on this wall. But if all the external parts of the wall are sealed and OK, then it's mostly aesthetic considerations you need to take into account. And structural integrity, of course. If it's not a gable wall, then it's probably carrying a load from some part of the roof. In that case, it's directly unsuitable to remove anything from it that belonged to the original construction.
Yes of course you need to be 100% sure about what it looks like underneath, but if you have added insulation yourself and haven't had any problems, then it feels pretty safe to put up drywall.JanneL said:Well, if the house were mine, I would be interested to see what it looks like under the additional insulation.
