Basics of Home Insulation

20 July 2012

As you know, home insulation is an important and necessary step for an energy efficient home. Insulation helps us use less energy to heat in the winter and cool in the summer- which means more money in your wallet!  The Federal Trade Commission and Energy Savers are helpful resources for basic insulation knowledge. Below are some highlighted facts,

Main rule: Higher R-Value = Higher Insulation Value

So what is an R-value? R Means thermal resistance. This is also explained as the resistance to heat flow. Higher R-value has a greater insulating effectiveness.

How much should I have in my home? This all depends on the climate, and age of your home. In our chilly Minnesota climate it is best to have a fairly high R-value compared to other areas of the country. To get an estimate of what your R-value should be, use this cool Zipcode Home Insulation Calculator.

Different insulation for different areas: In general, higher R-values should be put in places like the attic with lots of exposure to the outside air. To be sure, sign up for a home energy audit!

    The R-value is less of an issue in the UK, where the regional temperatures don’t tend to differ all that much. Still, it is always a good idea to ask a surveyor which insulation solution they believe would be best for you anyway.
