5 Energy-Saving Myths About Insulation That Are Costing You Money

Installing insulation is one of the most effective ways to improve your home’s energy efficiency and reduce utility bills. However, there are a lot of myths surrounding insulation that might prevent homeowners from making informed decisions. 

These misconceptions could cost you money and comfort and harm your home’s energy efficiency. Below, we’re setting the record straight on some common insulation myths.

Myth #1: Insulation Only Matters in Winter

Many homeowners believe insulation is just about keeping the house warm during the colder months, but that’s far from the whole story. While insulation does help retain heat during the winter, it also keeps your home cool in summer by preventing hot outdoor air from seeping in. 

Quality insulation improves temperature regulation year-round, which means less reliance on heating and air conditioning systems – and more energy savings.

Myth #2: Adding More Insulation Always Equals Better Results

It’s easy to assume that more insulation is always better, but this isn’t necessarily true. Insulation’s effectiveness depends on proper installation and ensuring the right type and amount for your home’s needs. 

For instance, if parts of your home, such as the attic, have air leaks, adding insulation without sealing those gaps first won’t yield great results. Air sealing and targeted insulation upgrades work best to create an energy-efficient home.

Myth #3: My Home Already Has Insulation, So I Don’t Need to Worry About It

Insulation isn’t a one-and-done solution; it deteriorates over time. Factors like moisture, pests, or improper original installation can compromise its efficiency. 

If your Maine home feels drafty, your energy bills are unusually high, or your HVAC system works overtime to maintain a steady temperature, it may be time to reassess your insulation. Professional assessments can identify weak spots that might be wasting energy and money.

Myth #4: All Insulation Materials Perform the Same

Not all insulation is created equal. Some materials work better in certain applications than others. For example, fiberglass insulation may be effective for straightforward installations, but spray foam insulation offers superior sealing and durability, particularly in attics and basements. 

Choosing the right material is essential based on the climate, your home’s structure, and your energy goals. Consulting with experts like Seal It Insulation ensures you pick the best fit for your needs.

Myth #5: Insulating Unfinished Spaces Isn’t Worth the Investment

Unfinished spaces like attics and basements are major culprits for home energy loss. Proper insulation in these spaces improves overall energy efficiency and makes them functional for storage or even living space conversions. 

Even if these areas aren’t regularly used, insulating them prevents unwanted temperature fluctuations throughout the rest of your home, helping you save big on energy costs.


Ultimately, proper insulation is an investment that pays off through energy savings, improved home comfort, and even higher property value. By understanding the facts and working with a trusted insulation professional, you can avoid costly mistakes and maximize your home’s efficiency.
