We are currently sealing our windows with butyl tape as instructed by the window installer. According to him, we only need to apply the seal on the sides because we have roller shutter cassette boxes. The boxes are flush with the ceiling-level lintels and have been filled with expanding foam. In his opinion, the plaster ensures the seal at the top.
Does anyone have experience with this topic? I prefer to be on the safe side and wonder whether we should also seal the bottom of the window with butyl tape.
We need to build as airtight as possible since we are installing a ventilation system.
Thank you!
Best regards,
NundE

I noticed that, but I still thought it made sense to respond.
There’s no point in discussing this now since it’s probably already resolved (otherwise he would have followed up by now). For me, it still makes sense to reply because I don’t like to leave statements like the one about the “airtight assembly foam” unchallenged...
Also, a construction project doesn’t necessarily end with the final inspection, since any defects that arise may still need to be corrected during the warranty period...
