Hello everyone,
I want to install a vapor barrier around the collar beam. Unfortunately, there are several problems with this. For example, the rafter purlin anchor is in the way. I have already tried to tape around it. Unfortunately, I have to find that the foil is then not airtight.
I have some ideas, but I am very unsure. A simple but perhaps not nice solution is to saw the anchors and bend the metal parts that are in the way. The rafters are mainly attached to the collar beam at another point. Of course, it would be better to move the anchors to the back of the middle purlin. Or you solve the problem completely differently by installing OSB boards in the cavities and then sealing them all around with reinforced tape.
What is your assessment or what ideas would you have?
Thanks & best regards
Billie
