Dachdämmung auf Sparren einbauen - Wärmedämmung

I have an old building that will become our new hoTodi.tv studio. The rafters, battens, and roof tiles are already in place. Unfortunately, there's no vapor barrier on the outside, so I have to come up with an alternative. For this, I'm using special thermal insulation made of polystyrene insulation boards with a thermal conductivity of 0.040 W/(m·K) and a thickness of 80 mm. The special feature is the tongue-and-groove system, which creates a complete seal across the surface, thus eliminating the need for a vapor barrier. hoTodi shows how it's done! If you have any suggestions for a video, just let us know, and we'll see what we can do. And we'd be very happy if you subscribed to our channel!
