Is there something I can put on EMT to prevent condensation? Im installing conduit up north where it will get very cold. Im not sure how good of a job the insulators will do because its up in a vaulted ceiling, no attic space.
I wouldn't think there should be any issue.
Im worried about the pipe not being covered by the insulation. The home is more or less a vacation home for now, so it wont constantly be warm . There will be times when it cold then hot then cold again. Im worried about the same problem with my can lights also.
