Bridges, are they as good as you think?

When we think of bridges it almost always has a very positive image in our mind.  Bridges get us from over here to over there or they close gaps between people and our understanding of others.  What could possibly be wrong with a bridge?

If we are going to be a tad more accurate let’s understand that today we are talking about Thermal Bridges.  A Thermal Bridge is not like today’s photograph of our beautiful Champlain Bridge that connects Crown Point, New York and Addison, Vermont.  But, I digress from Thermal Bridges.

A thermal bridge is a component part of your home that conducts heat very well.  There are materials that conduct heat well such as aluminum.  There is a reason that most cooking pots and pans are aluminum and that is because aluminum conducts heat very well and that helps cook your food such as wonderful Comfort Food in the winter; sounds good!  But a Thermal Bridge in your home will conduct heat from inside the home to the outside.  That is called Heat Loss.

Heat Loss is wasting Energy, costing you money, and damaging the environment.  All that happens all at the same time.

One of the biggest Thermal Bridges in your home is the structural lumber.  Yes, the actual pieces of wood that are used to “frame” the structure of your home are great transmitters of heat.

  • Wood / lumber is a material that heat moves through very quickly and efficiently.
  • The lumber is a huge Thermal Bridge.
  • Warmth in your living room moves quickly through the lumber and escapes outside and is lost.
  • As heat is lost it is necessary to replace that with more heat to keep you warm and comfortable
  • Heat Loss demands more energy.
  • Thermal Bridges are a significant source of Heat Loss.

If Thermal Bridges are bad and loose heat an easy and uncomplicated way to reduce the problem is simply to reduce the amount of lumber in a home.  Most homes are built using a system of 16” on-center construction but if we change that to a 24” o.c. system look what happens

  • In a wall that is 20’ long it is necessary to have 15 pieces of framing lumber 16” o.c.
  • In a wall that is 20’ long you will need only 10 pieces of framing lumber 24” o.c.
