We, my wife and I, also met with your representative on Tuesday, February 12, j.l. very pleasant. He took the time to explain to us why different forms of isolation were usefull or not in our case, and in this way helped us to come to a responsible decision, namely to have a layer of grains placed under the floor. This has already been done this morning (February 15), and now we are unfortunately less enthusiastic about the approach.
Nobody, your representative or the executors, has told us that the spraying of the grains is accompanied by a huge dust cloud. The whole kitchen, the gas stove, the pantry, the sink (with fruit and vegetables, crockery and electrical appliances on it) as well as the lower part of the stairwell were covered in dust. We have spent hours getting everything dust-free again. If we had known this, we could have taken precautionary measures.
But we find another downside more serious. From your representative we understood that someone would go under the floor to level the granule layer in order to obtain optimal insulation. But no one went underground (they did not even have dust masks with them). When, after the executors had left, we were shining under the floor with a lamp, we had to conclude that the surface of the layer of grain was not at all smooth, but very wavy, and that all kinds of rubble protruded above the grains. According to your representative, this would be covered by the grain layer.
In short, we are not satisfied and await your answer.
