Let’s poke a hole in the ceiling and see what happens.

For a week or so we have been wandering around down in the basement closing up and sealing off spots where there’s Cold Air Penetration.  We’ve looked at the tub, basement drain, crevice along the top of the foundation, hole where the water line enters, and so on.  So today let’s go upstairs to the first floor and see what is going on there.

Down in the basement we are fighting Cold Air Penetration.  Up in the house we are fighting The Path that warm air takes as it tries to escape from your house.

Cold Air Penetration 101.

So far we have talked about how Dense Cold Air basically forces it way into your home through all kinds of tiny cracks and crevices.  The air wants to force itself in because it is so much more dense and has a greater weight.  That weight pushes against the warm air inside and forces itself inside.

Today let’s look at some spots where the Cold Air Penetrates into your home.  Remember we are chasing those things that when fixed will make a significant improvement and are cheap.

And away go your troubles down the drain!

On Friday we got as far as the Septic Tank.  What happens next?  What happens inside that tank?

Today’s picture or drawing is fairly easy to see and follow.  As we all know there are many different and unique designs available for septic systems, some of which have been used for a very long time and others are new more technologically advanced systems.  The important thing to remember for today is that virtually all of the systems start with a relatively common septic tank.

Are there other types of foundation walls?

Yesterday we looked at Poured Reinforced Concrete foundation walls where forms are set then filled with concrete to create a basement wall.  Remember, everything sits on top of Footings that are always below the frost level.  Occasionally you will hear people talk about “Frost Walls” and wonder what they are.   A Frost Wall is typically only 4’ tall creating a crawl space, not a full usable basement.  Frost walls’ footings are just barely below the freezing point so they work just fine.
