Yesterday our good friends from Protan installed 130m2 radon-membrane for the library for FREE! The whole process took them about five hours, so now we are counting on a good indoor climate with no (low) radiation.
Today we hope to achieve these goals:
-One layer of 10cm insulation
-Topmembrane for the foundation
-Attach the plastic knobs with a plastic band on top.
We`ll post pictures later on!
