How do you prevent mold in a cathedral ceiling?
A balanced system of soffit and ridge ventilation provides continuous ventilation of hot, moist air at the hottest point of the roof. Even with the attic bypasses sealed and effective vapor retarders installed, proper ventilation is essential to prevent moisture problems in cathedral ceilings.

What’s better R13 or R15?
Is R15 Better than R13? Answer: There isn’t much difference between R13 and R15. However, higher R values offer higher performance. Therefore, in the case of efficiency, R15 is better than R13.
What is the difference between R19 and R30 insulation? There is a direct relationship between the amount of insulation and the amount of heat transfer. The bigger the R value, the better the insulation is at slowing down the heat transfer. So R19 is better insulation than R13, and R30 is better than R19. The larger the R value, the better the insulation value.
