Batt Insulation Upgrade Does More than Lower Your Energy Bill

When your home feels drafty in the winter, too hot in the summer, or your energy bills seem to keep climbing, insulation could be the culprit. Specifically, batt insulation—also known as blanket insulation—might not be doing its job as well as it should.

At Custom Insulation Company, Inc., we’ve helped homeowners throughout Massachusetts identify and solve insulation issues for decades. Here’s how to tell if your home needs more batt insulation—and what you can do about it.

1. Your Energy Bills Are Too High

If you’ve noticed your heating and cooling bills rising even when usage stays the same, your insulation could be underperforming. Blanket insulation may have settled, shifted, or deteriorated over time—especially in older homes.

What to do: A home energy audit can pinpoint which areas are leaking energy and whether additional insulation is needed.

2. Rooms Feel Uneven in Temperature

Do some rooms in your house stay chilly while others are warm? That’s a classic sign of inconsistent insulation coverage. Insufficient batt insulation in walls or ceilings can cause hot and cold spots throughout your home.

Pro tip: Pay attention to bonus rooms, finished attics, or rooms over garages—these often get overlooked during original insulation.

3. Drafts and Cold Floors

If you feel cold air creeping in around baseboards or floors feel icy in the winter, there’s a good chance the insulation in your walls or crawl space isn’t up to par.

Batt insulation is often used in exterior walls and between floor joists, but gaps or compressed batts can reduce its effectiveness significantly.

4. Your Insulation Is Old or Compressed

Batt insulation made of fiberglass or mineral wool can last for decades, but over time it can become compressed, damp, or even moldy—especially in basements or crawl spaces.

Signs of aging insulation:

• Dark or dirty spots on the insulation
• A musty smell in insulated areas
• Visible sagging or gaps

5. Your HVAC System Runs Constantly

If your furnace or AC never seems to shut off, your home may be leaking heated or cooled air. Inadequate batt insulation in the attic or walls can cause your system to work overtime.

Solution: Adding new batt insulation—or supplementing it with spray foam for tighter air sealing—can reduce system strain and lower utility bills.

6. You’ve Just Renovated or Added Living Space

If you’ve recently finished an attic, added a room, or remodeled a basement, don’t forget about insulation. These areas often lack adequate batt insulation, especially if they were previously unconditioned spaces.

Don't skip insulation: It’s much easier and cheaper to add it during renovation than to retrofit later.
