Hello,
I have a question. We want to build an ecological, well-insulated house and have therefore looked for "eco-house" providers. Now we have received cost estimates from different companies and suddenly the eco-house no longer has wood fiber insulation or cellulose insulation in the walls but mineral wool instead. Of course, it is supposed to be very ecological as well (according to the company), because it has the Blue Angel certification (this is from Knauf).
I am a bit shocked because I actually wanted a house with timber frame construction and insulation made from renewable raw materials. That means wood, possibly hemp, coconut fiber, or if it weren’t so expensive, sheep wool.
What do you think about the mineral wool from Knauf with the Blue Angel certification? What are the disadvantages, and what are the advantages of wood-based insulation, for example? How is it with the feeling of the room? Can you notice a difference?
I would appreciate your opinions!

I also care a bit about my ecological conscience. Wood fiber is a renewable resource. Mineral wool, I believe, consumes a lot of energy during manufacturing.
The question for us is whether you can actually notice the difference in the house. Whether wood fiber simply creates a better indoor climate.

Username_wahl27 Sep 2015 19:25We happened to find an architect who is passionate about timber houses, and now we are building one ourselves using a timber frame construction with cellulose insulation. In the meantime, we have had the chance to tour several timber houses from the inside, and we wouldn’t want to build anything else now. It is simply very cozy when the wood is left visible. Additionally, the construction time is shorter, and the walls offer good insulation despite their slimmer thickness. Since we are also covering all the interior walls with wood, we save the effort of having to paint the entire interior.

I’m also somewhat concerned about my ecological conscience.Maybe you should read a publication from the Fraunhofer Institute on this topic. The key conclusion is:*"Studies have shown that in buildings where large thermal masses are installed in the roof space, such as thick plank sheathing or concrete slabs, the heat storage capacity of the insulation between rafters with typical bulk density plays a minor role. The influence of the heat storage capacity of the insulation between rafters can also be neglected when larger window areas are present in the roof surfaces, because the difference in phase shift between mineral wool and wood fiber insulation boards decreases as the window area increases."
