Shed condensation

It’s the time of year when everyone is observing condensation. There are many circumstances , reasons, conditions etc. that we could talk about. Here is an example of one circumstance, an unconditioned shed.

The inside  temperature of the shed equalises with the outside temperature on a frosty morning. The relative humidity is also similar both inside and outside. As the morning sun hits the building, the external surface temperature rises. The external surface temperature is now higher than the inside temperature causing condensation to occur on the inside of the window.

This scenario is worth thinking about when considering an unheated room in your house. A house generally has a higher internal humidity level than a shed does due to household activities and that fact that the occupants breathe. This puts an unheated room at a high risk regarding condensation. Food for thought.
