- Oliver: With wood insulation! Is that even That sounds unusual, it's actually a really exciting solution in area of energy restoration. Especially when comes to sustainable construction, heat protection and a good space climate, wood fiber insulation become more interesting. So that's we're to what wood fiber insulation is exactly, where you can use and what advantages it really and where the limits So let's Wood fiber dams are mainly of residual wood, from materials that the wood industry anyway. example, forest wood, hobel spades or pieces of sawdust. These wood remains are then de-fibered, processed and then pressed into dam plates, or inflatable dams. What I particularly exciting, often even the natural lignin of the wood as a binding agent is i.e. the wood glue, one could say. This means that the production is almost without chemical bonds. This is a plus. However, any additional substances, is not There is fire and moisture protection. For purpose, substances such as ammonium sulfate are used. Nevertheless, wood fiber remains a very natural evaporative Technically, the evaporation is quite significant. The thermal conductivity is between 0.04 and 0.055 watts per meter and Kelvin. This means that good thermal protection in winter and the time excellent protection against summer heat. And that is a point that becoming increasingly important in Wooden fiber insulation has relatively high raw density and heat storage capacity or simply put, we can always take up and give them up This is what makes the roof floor apartments and upper floors heat much slower And this is where wood fiber insulation is much better than classic insulation. And then there is another point that important, wood fiber solvents are diffusion-free. That means that the construction sheet is breathable. We had a few times when it about space climate. Moisture can be absorbed and same time rejected. This creates a very pleasant space climate and the same time, and this is particularly important, the risk of molding Because all the bells when it to moisture. Especially with old buildings and sensitive existing buildings, this is a big advantage. Another big advantage is the sound protection. The open-pored structure absorbs wood-fiber sounds very well. You in the roof area or inside walls. you can as a step-shutdown under laminate or wooden floors. This reduces steps and running noises and the floor feels warmer at win-win situation. Now the question where can wood fiber insulation be And think what I said takes the answer bit ahead. That's almost everywhere. So we can as roof insulation, as saving between or under saving insulation. We can it on facades, either as a insulation system and as a insulation in between, or as a floor insulation under lamination or parquet. And I just said, even inflatable insulation can be made it. So it's a very versatile insulation. And I find it interesting that these wood fiber plates are directly capable This makes them exciting for heat-shrink-connection systems during restoration. And at the time, the wall structure remains open to diffusion, so that moisture can from the building. Also technically, you really very good values there to today's requirements. There, certain applications, are about 18 cm in And that shows that wood fiber is not only environmentally interesting, but can also be absolutely competitive We often about 18-20cm, but that's a good point. Of course are points that you have address Wood fiber insulation is really not the cheapest insulation on the market. on structure, the material costs around 55-70€ per square meter without installation. Complete renovation in the roof area can also expensive but hey, point. In wood fiber belongs to the B2 and is considered to be flammable This does not mean that it insecure, but there are other dams with higher fire protection classes. Therefore, you really to individually which structure and which material fits the building. Nevertheless, I think you can good case for wood fiber, especially because of the natural material, summer heat protection and the pleasant space climate. But the issue really very, very good Wood fiber consists of mature raw materials, stores CO2 and can even be and energy-efficient This means that it is more sustainable than conventional insulation. So who is interested in I people who only at the U-value, but also at living comfort, sustainability and heat protection, especially in roof floor or high-quality renovation, this can a really good solution. And that's wood fiber is becoming more more in new buildings and in energy renovations. A few words from me. My name is Michael Suhr. am the founder and manager of Reneva.
