Determine dew point in wall assembly
Webdescribed below, determine if a recessed vapour placed in the wall assembly would be at risk of having water vapour condense on its surface. Steps to solve this problem With the inside temperature given on the wall assembly and an interior RH of 45%, calculate the dew point temperature of the air/vapour mixture.(Hint: see your notes on Psychrometrics … WebIf the dew point occurs within a wall the wall materials at that point will become wet, which can cause material damage, reduced R-value of insulation and mold. The drop in air temperature required to reach dew point and cause condensation is shown in Figure 1. For a relative humidity of 80%, a drop of 7 ⁰F is required. For a relative ...
