Little strange experience. We received a letter that homes in our neighborhood are being isolated by means of a collective, which means that e.e.a. would be cheaper. Because we are busy with making our home more sustainable, we have invited an advisor. The man, although extremely friendly, arrived two hours before the agreed time. He stayed five minutes. After looking around once he said that he can not mean anything to us because we do not have crawl space. Only then it became clear to me that floor insulation is their (only) expertise. This has not been communicated at the front. Sin of his time and mine. Still 3 stars because I am friendly.
