Vapor Retarder Installation Room 2-1 (Dampfbremse anbringen Zimmer 2-1)

Yesterday night we started the installation of the vapor retarder in one of the rooms upstairs. Since this is our first time to do it, we planned to install it as a whole. Unfortunately, it did not work. It was too heavy and to complicated to open the whole folded vapor retarder. To avoid destructions or making holes in the vapor retarder, we then decided to cut it into smaller length and then install it.
