The electricians have now installed the wiring in our new build, resulting in quite a few holes in the vapor barrier in the ceiling. The guys have at least started patching up the tears with tape... but with "packing tape" from Biltema! I have just purchased a roll of "age-resistant" and suitable tape that will be handed over to the guys tomorrow. I don't really think it feels professional to use Biltema tape to repair the vapor barrier. Is there anything else I should be on the lookout for?...
