Home insulation plays a critical role in a building’s energy efficiency, comfort, and long-term structural health. However, many homeowners—whether attempting to do-it-yourself or working with a contractor—make mistakes that can reduce insulation’s performance and lead to costly problems like moisture issues and drafts. This article will highlight nine of the most common insulation mistakes and how to avoid them.

Gaps in insulation can significantly reduce its effectiveness, allowing warm or cold air to escape and drive up energy bills. The solution is to ensure insulation is fully installed with no voids, paying special attention around electrical outlets and plumbing. In addition, it’s important to use the right type of insulation for each space, utilizing advanced options like isolation urethane that can seal gaps and provide superior air sealing.

Common Insulation Mistakes and How to Avoid Them

Mold, mildew, and wood rot can occur when insulation is installed in areas with existing moisture problems. It’s also important to remember that a well-insulated home must be properly ventilated to prevent moisture from accumulating in the attic and crawl spaces, where it can degrade insulation and cause ice dams in winter.

Most insulation materials can absorb moisture, reducing their R-value and thermal resistance over time. Moisture control is an essential component of any insulation project, whether it’s fiberglass batts or more advanced options like spray foam or cellulose. Icynene spray foam insulation, for example, is moisture resistant and requires no additional compression during installation. This is a major advantage when compared to other insulation types that can easily absorb moisture, leading to mold, mildew, and water damage.
