Make a plan for old building insulation - How to proceed?

Ever launched something on the market?

Unfortunately nothing that, after a revolutionary development, still isn’t correct or needs to be adjusted and corrected seven years after market launch. Or where the product was sold for seven years with features that apparently are suddenly completely different.
And also no product that did not have correct documents and certificates at market launch.

I don't believe the OP either. But I am surprised about the CE discussion here. As far as I know (and at least the Wikipedia article seems to confirm this), CE is a self-declaration by the manufacturer and has nothing to do with external testing. The manufacturer confirms that their product complies with the relevant regulations. Nothing more. A matter of course, actually. When talks about a (missing) four-digit number, it is optional, and as far as I know, nothing needs to be uploaded to a public register either. It is sufficient to be able to present the (often self-created) test documents upon request. Any objections?

Objection?

Sort of. The CE marking is done by the manufacturer himself. However, he has to comply with certain requirements, e.g., also how the testing is to be conducted.

There is also a checklist from the DIBt – which I have posted before – on how the CE marking must necessarily look. And here it already starts with the OP that not even the prescribed font is used. Not to mention other points.
In addition, there should also be a performance declaration for the product if it is covered, for example, by a harmonized standard in the EU. This includes, among other things, the testing of thermal conductivity according to DIN such and such. This performance declaration is also not available for the product – the contractor MUST have this performance declaration, for example, to meet the state building regulations.

Again: Without proper evidence, I could also equate a latex paint stirred by virgins at full moon with this product. At least formally. For a thermal conductivity WLG 32 (i.e., EPS or the like), the product is currently also marketed in CZ/PL/Thailand (also with correct CE marking after initial testing). That seems more realistic.

Then the question arises with WLG 032 how I would manage to hold 14 cm of it :p

Holding makes me less worried. But at about €38 per m² with a 3 mm layer thickness, I don't want to pay 14 cm :eek:

Documents from sales have arrived and have been forwarded to my advisor. Let's see what he says.
