The Trouble with Lumpy Insulation

The Trouble with Lumpy Insulation

You need an even layer of insulation to reap the promised energy savings.

Proper insulation is essential for an energy-efficient home. Unfortunately, insulation problems are common. Some older homes may never have had any insulation at all, and even in newer homes, there is the potential for the insulation to shift, settle, or be damaged by bugs, mold, and moisture.

The Trouble with Lumpy Insulation

If you aren’t happy with the amount you spend on your heating and cooling bills, it is certainly a good idea to have a professional check on your insulation. They may very well discover that you need new insulation.

However, when choosing your new insulation you absolutely must keep this fact in mind:

Insulation must be installed evenly.

Lumps in your insulation can devastate any product’s energy efficiency. Here’s an example:

Let’s say that your attic is supposed to have R-30 insulation, but it’s piled up in lumps so that some areas only have the equivalent of R-10 insulation and other areas have the equivalent of R-50. Let’s also assume that the lumps are distributed evenly so you have 50 percent lumps (R-50) and 50 percent troughs (R-10).

Because heat always follows the path of least resistance, you will actually find that more than 50 percent of the air leaving your home goes through the R-10 areas. In fact, if you do the math you’d find that the R-10 areas allow 3 times as much heat to escape as they would if they had R-30. The R-50 areas won’t deliver much more protection than R-30 (because most of the heat is attracted to the much more vulnerable R-10 areas).

End result: Your lumpy insulation will allow 1.8 times as much heat loss as a properly installed, flat layer of insulation would.
