Tape separating from polyiso
Last year we insulated a kneewall space with rigid foam (polyiso). The difference is amazing and we absolutely love it.
One small problem is I noticed the tape that was used across the seams is beginning to lift slightly. Photo attached. I don’t know what tape was used.
Any suggestions on how to keep the tape edges down, short of re-taping everything? Is there a glue or adhesive I can apply across the tape to foil boundary?
