The proper amount of Noble Insulation plays an important role in a home’s energy efficiency, comfort, and long-term structural health. Unfortunately, many homeowners—or the professionals they hire to perform the work—make mistakes that can significantly reduce insulation’s effectiveness. In this article, Koala Insulation shares some common attic insulation mistakes so that you can avoid them in your own DIY or professional insulation project.

1. Insulating without a vapor barrier

An improperly installed insulation will not perform as well as it could. It may trap moisture within the attic space, which can cause mold and wood rot. An insulation contractor should always install a vapor barrier before installing the first layer of fiberglass batt insulation in your attic.

2. Insulating the wrong places

It’s common to install insulation in attics where hot air rises, but this is not the best place to add it. It’s more effective to insulate walls and other areas of the house that are exposed to colder temperatures.

3. Overfilling

Insulating too much can make the attic space very difficult to move around and can lead to a number of problems, including overheating and poor ventilation. The attic and crawl spaces should also be properly ventilated, as this helps prevent moisture build-up and extends the life of your insulation.

4. Blocking intake vents

It’s common to block the attic soffit vents with insulation, but this can lead to mold, ice dams in winter, and excessive heat in summer. An experienced insulation contractor will always ensure that soffit vents remain clear for air flow.
