- Oliver: You can rely on it, summer will at And then there a topic that many know, summer heat in the attic. When the thermometer still around 25-28 degrees, it like you're in a sauna In you the windows, hope for cooling and still the air stays simply uncomfortable warm. Especially when the bedroom is under the roof, it gets exhausting because good sleep looks different. Especially in older buildings with little or outdated insulation, the temperatures in the attic in summer can over 30 degrees and stay there. Many think that a insulation keeps the heat in the house. That will be much warmer but that is a widely spread illusion. A insulation does not between summer and winter. So it does not recognize which direction the heat is coming Its task is always the same, the heat current. That means that winter the heat stays in the house and in summer the heat stays outside And that's a good roof insulation can a huge impact on your room climate. To this three things particularly important. The first and most important point is the roof insulation itself. is not about any insulation material, but the right solution. Let's take a classic intermediate insulation with mineral wool, i.e. the insulation between the wooden beams of the roof. least 20 cm of insulation strength is preferred. Even with a wood-fiber insulation, which above the slabs, is to improve the heat protection in winter and summer. With some pure or pure insulation, about 14 cm You can to the podcast we did with Alexey or with Matthias, where it also about the roof. You really to vote on how much space available and what effect you to achieve These materials have very good damping properties, so can the thickness a bit. But even if a complete roof renovation is not planned, are possibilities, like many regions, of inflating damping, where the areas are with damping material This can the heat protection, even if to the top the bullet cover. In addition to the damping, should be a second topic on the screen when it to summer. A dark roof can on sunny summer days. to to 70 or 80 degrees. So can kind of a mirror egg on The roof itself is sometimes hotter than asphalt in the high summer and without insulation, this heat slowly but continually your rooms. The second important point is something that is not often mentioned the screen, namely heat storage. This is about how good materials absorb and off time-consumption. When building the roof slats are often with drywalls. Instead of just one layer, some really two layers of drywall. We have already seen and implemented Simply because the additional mass simply like a heat buffer. Heat is then absorbed and slowly down to the room. This that the rooms heat less quickly. And maybe another small point. Wood fiber solvents are often not only for their insulation properties, but also for the high heat storage capacity. They can for and late, which can a real advantage An important factor is also the sun protection itself. Because you can imagine, the best insulation cannot fully unfold if the sun through the roof window Especially important are therefore external solutions such as roll-in, marquises or jalousies. Because if you imagine, you the curtains inside, that's nice and good, but then the heat is already in An external sun protection can a large part of the solar energy. The inside curtains help a but the heat is also in room. If these factors play i.e. good insulation, heat storage and meaningful sun protection, a much more pleasant room climate And besides, this is also an important topic, you energy. How much depends on where you start But a subsequent roof insulation can energy consumption by 10 to 20 percent. As a comparison, you often the head. So you put on a wool hat or, to in the summer allology, you just on a cap and protect yourself from the sun heat. In addition, for a roof insulation, are of promotion options, regardless of whether you energy or improve the heat protection in summer. A roof renovation does not only ensure a nicer roof it also how your home feels. And I know we often about energy costs, about CO2 costs But that's just one side of the medal. On the other side, it's always about feeling in the rooms and And there is a insulation very, very important, so that it not too hot, not too cold, so that it pull Because especially for owners and own users, this is really a topic that you should all desire to save and to lower And with the roof insulation, has the nice advantage, that both it at time. If you need help, then I would like to to the to topics, also on subject of core insulation and roof insulation. you in the show notes. But if you hear that and the sun is just it, because the sooner summer comes, the faster it again.
