WebWith typical humidity, the dewpoint is in the mid-40s, so it’s not cold enough for water to condense. If, instead, only an inch (R-6.8) of foam was installed with an R-19 batt, then the interface temp would be more like 35, which would make it rain in the cavity. WebDew point is the temperature to which air must be cooled for water vapor in it to condense into dew or frost. At any temperature there is a maximum amount of water vapor that the air can hold. This maximum amount is called water vapor saturation pressure. Addition of more water vapor results in condensation.
