ᐅ Swedish Prefabricated Panel House / AB-Elementhus Renovation vs Demolition

Hello everyone,

We have purchased a Swedish prefabricated house from the company AB-Elementhus. It features a solid masonry ground floor, on top of which the prefabricated house is built.
Initially, the plan was to completely demolish the house and replace it with a new cross-laminated timber (CLT) structure of the same size.

While studying the building documents and permits for the AB-Elementhus house, I was positively surprised by the construction.
The wall assembly is (inside to outside) 2cm (0.8 inches) cross-laminated timber, 16cm (6 inches) compressed wood chips, 2cm (0.8 inches) cross-laminated timber, and 0.2mm (0.008 inches) stove-lacquered aluminum.
The planned layout of the new building could be realized within the existing structure, so I am now considering renovating and upgrading instead of demolishing (insulation, interior, windows, etc.).

Does anyone have experience with these houses?

Best regards,
Harv

Hello,
since you have so much experience: Do you know anything about pollutants in houses? Wood preservatives, etc.?
I would appreciate any information.
Thank you very much

Hello dear experts on Swedish houses,
I’m not sure if my previous inquiries to Harv and Ibsylon were received, so here is another attempt:
Can anyone tell me if these houses (especially the prefabricated house “Landskrona” from the 1970s) contain any harmful substances, such as wood preservatives, asbestos, or similar?
Best regards

If they were private messages, then no, because all participants must have already written more than 150 posts.
But here in the thread, your one question can now be read three times publicly. That’s unnecessary, according to Knut Buttnase.

To my knowledge—I have been living in "Landskrona" since 1974—you don’t need to worry about that.

The black panels under the concrete stone façade ("Coloroc") are called "Asfaboard" or similar, which is asphalt = bitumen.

Definitely not asbestos; I wouldn’t know where it would be.

For example, in our house, after completion, chipboard was installed on the upper floor’s floor. It was bought locally and smelled bad for a very long time. Back then, people were not as informed about how unhealthy that was...

So you might not know if everything is still in its original condition.

The wood preservatives used in the roof truss—I remember—leaked out during rain while it was being installed; apparently, they were water-soluble.

But: I am by no means a construction expert or anything like that!

Where exactly is your "Landskrona"?

Good luck!

Our test results were negative!
There was no asbestos anywhere in the house!

If you have concerns, you can also simply have a laboratory test done.
The costs are reasonable.

We are currently finalizing the interior construction!
We have just installed the flooring (solid oak).
We tried to minimize moisture inside the house because of the wooden structure.
