Where cold air goes

The other day we talked about Cold Air Penetration and you will see for the next several weeks that we frequently talk about it.

So……., here’s a fairly bold statement that is sure to conjure up reactions from some of our readers.  We contend that stopping Cold Air Penetration is the number one secret to cutting back on Heat Loss.

Here is how it works.

  1. Dense air that is heavy and typically cold falls to the earth and searches for a lower spot because of its weight.
  2. In addition to the weight of the Dense-Cold air don’t forget that the atmosphere is on top and its sheer significant weight is also pushing downward
  3. If possible that cold/dense air continues to look for “The Path of Least Resistance”  We will examine specific ways to close off those pathways.
  4. Any opening, hole, crack, crevice, aperture, slit, space, and so on in your home is a wonderful place for the cold air to squeeze through and enter your home.

So, as the cold/dense air penetrates into your basement it is immediately warmed because it has entered a “treated-space.” ( Brief explanation:  a Treated Space in a home is an area where it has been warmed. )  Once inside the dense/cold air expands in volume or Mass as its temperature rises. 

Just like a balloon that is filled with hot air it expands.  The other day we had a photograph of Hot Air Balloons flying over Lake Champlain in Shelburne Bay, the point of that photograph was to demonstrate how the hot-air expands inside the balloon which then rises.  Today’s photograph shows another Hot Air Balloon up near Stowe Vermont but during the winter.

All this is part of a very important rule.  Cold Air always moves towards warm air.  Or in other words, Dense Air always moves towards Thin Air.  That is a very simple but completely true explanation for Cold Air Penetration and we are saying that Cold Air Penetration is the number one cause of Heat Loss.
