How do I know that? Because the Department of Energy recommends attic insulation for the Greenville Climate zone of R-49 or more. They base this on our particular climate, weather patterns, building construction, and energy costs. Even if your home is brand new the code requirement for our area is an R-30. This is because the lobby for the South Carolina Home Builders Association lobbies to keep new home construction costs down. As a result, even a brand new home has approximately 40% less than what is needed to make your home energy efficient! Imagine if your house is fifty years old, like mine, and has never had any more insulation installed since it was built. We see this weekly. A home like this will often have the equivalent of R-10 or less, or one FIFTH of what is recommended by the DOE!
Attic insulation is particularly important for a number of reasons. First of all, it provides a thermal buffer between the ambient area in your attic and your home directly beneath it. What this means is that in the summer the insane heat (often approaching 140-150 degrees) has less chance of making it all the way through to your ceiling via conduction, and conversely in the winter the heat in your home has less chance of moving out of your house and into the cold above. It acts like a nice blanket to keep your house cozy. Since heat rises (in the winter) your attic is the first place to prioritize insulation. What a lot of people don't know is that heat actually moves DOWN into your home in the summer. This is because heat moves to areas of cold, or from high pressure areas to lower pressure areas. The less likelihood of that blazing heat making it to the ceiling in your home the cooler and more comfortable your home will remain. This saves wear and tear and additional use of your air conditioning system, saving you money!
