Is Foam Board Considered A Vapor Barrier. The insulation can prevent a large. the answer is yes! vapor barriers with a permeability rating of 0.01 perms or lower are considered effective in preventing moisture transmission. in general, if the foam rigid insulation is installed correctly and sealed properly, a vapour barrier may not be necessary. A vapor barrier helps to keep moisture from seeping into your insulation and causing it to lose. the short answer to this is that rigid foam board, when installed to the correct specification, acts as a vapor barrier on its own. The temptation to fit an additional barrier should be avoided as it would most likely lead to trapped moisture within the wall assembly. So, as long as you have a tight seal, you shouldn't need. Rigid foam insulation doesn’t need a vapor barrier. foam boards are typically considered a form of vapor barrier (especially with the foil face) by default. for zones 1 through 4 (except marine 4), any thickness of foam is suitable as the sheathing is warm enough to avoid condensation problems. It’s important to check your local building codes to determine whether a vapor barrier is required for your insulation project. does rigid foam insulation need vapor barrier?
