To the renovation calculator ???? https://schlau-energiesparen.de/sr?ut... In this video you will learn how you can not only save energy costs through targeted insulation measures, but also significantly increase your living comfort. I will show you which insulation methods in the price range from 20 euros to 5,000 euros are particularly effective and how you can even carry out some of them yourself. Drafts through roller shutter boxes or leaky windows can be the biggest waste of energy in your home? And did you know that you can make significant savings with simple means such as sealing your floor hatch or installing insulation layers in old roller shutter boxes? Together with insulation expert Arnold Drewer, I will explain the best and most cost-effective insulation methods to you step by step. Arnold gives you valuable tips on how you can take action yourself, for example by insulating radiator niches or having blown-in insulation materials inserted into your floor. We will also show you how to insulate your upper floor ceiling or even a crawl space efficiently and inexpensively.
