My Norwegian isn't very good so excuse my writing in English. I have insulated my loft and set in fuktsperre on the warm side. I have taped the joints but am having problems sealing the bottom against the floor. I have taped it and screwed a spikerslag over the joint. Without taking up the floorboards, I can't see any other way of solving this. My question is 'how important is it that the fuktsperre is 100% tett? House is from 1953.
