If you’ve ever looked at your energy bills and thought, “Why is my attic turning into a sauna every summer and an ice palace every winter?”—you’re not alone. The culprit might be something most folks don’t even know exists: insulation baffles.

In this episode, we’re diving deep into one of the most overlooked—and most important—parts of your attic insulation system. Mike shares real stories from 40+ years in the field, including what happens when baffles get skipped, how they actually work, and why they can make or break your home’s comfort and efficiency.

You’ll learn:

  • What insulation baffles are and where they go

  • How they protect your attic from moisture, mold, and heat damage

  • The connection between airflow and R-value (and why it matters)

  • When baffles are non-negotiable—and when they’re not needed

  • What to know if you’re using spray foam insulation

  • How we install baffles the right way at Nealon

  • Signs your attic might be missing proper ventilation

We’re not here to throw jargon at you or sell you something you don’t need. This is straight talk for Connecticut homeowners who want a home that stays dry, comfortable, and energy-efficient year-round.

Whether you're upgrading insulation, battling ice dams, or just curious what those red flags in your attic might mean—this episode is your starting point.
