Doorbell Installation questions, answered by experts

You do not always need to remove old insulation before adding new. If the existing insulation is in good condition—not wet, physically damaged, moldy, or infested with pests—you can add new insulation directly on top of it for a compounding effect. You can also mix different types, such as adding blown-in insulation around existing fiberglass batts.

However, removal is recommended if the old insulation is compromised by water damage or pests. You should also remove it if you plan to install a different type of insulation, like switching from roll or batt insulation to spray foam. If the existing insulation is very old or damaged, you will likely get more benefit from removing it and starting fresh.

DIY insulation installation is feasible, particularly for basic rolls or batts, if you have the right protective gear and knowledge. However, hiring a professional ensures even, full coverage for maximum efficiency.

Fiberglass is considered a favorite garage insulation choice due to its combination of affordability, ease of installation, and overall effectiveness. Fiberglass provides good thermal resistance, helping regulate garage temperatures and minimize heat transfer. Additionally, fiberglass is moisture-resistant, reducing the risk of mold or mildew formation.

If you’re using faced insulation with paper, face the paper toward the inside of the room during the installation process.

A good way to remember this is that the paper should face the “warm side” as it’s the vapor barrier, meaning it should face toward where the heat will be coming from.

Through R-value assessments based on climate and existing insulation.
