How Much Attic Insulation Do I Need?
A good rule of thumb is that the insulation should measure several inches past the joists, but ultimately, you’ll need the measurement itself. Your local climate impacts how much insulation is considered adequate. Colder climates require a few more inches of insulation compared to climates further south. This added insulation helps protect against the bitter cold and long winters more common in the northern part of the country. While a thick layer of insulation is beneficial, the overall efficiency is also affected by the materials used. Some materials are more insulating than others, making them better at minimizing heat loss. This resistance to heat flow is known as the R-Value
Can I Have Too Much Insulation?
While it seems correct to assume that more insulation means higher energy efficiency, there’s such a thing as too much insulation. Excessive insulation can encourage mold growth and trap other airborne particles within the fibers. Unless you’re experienced with evaluating and installing home insulation, it’s best to leave the job to a professional.
