What is Interstitial Condensation in Walls or Roofs? (And how to stop it!)

...dew point temperature, and for interstitial condensation this condensate (or release of moisture) occurs within the core of the wall, forming water that soaks into building materials. This may sound just like the surface condensation you would see on windows, however it is not. While the mechanism is the same science...

Condensation on windows is a pain but is it a problem & how to stop it?

...dew in drywall and furniture. Condensation is bad news in multiple ways – it indicates where a home has weak spots or thermal bridges in its insulated envelope, it points to problems in high humidity levels in the home – possibly coming from hidden problems in basements, crawlspaces, walls or ventilation systems – an...

The Difference between air barriers and vapor barriers

...dewpoint in a wall is the point where the drop in temperature causes air to contract, and water vapor turns to liquid. Since the warmer the air is the more moisture it can hold, where the dewpoint will be in your wall is determined by the difference in temperature from indoor to out, and the amount of moisture in the a...
