Blown-In Insulation: Building Science Deep Dive is a practical, no-nonsense podcast for homeowners, builders, and energy-efficiency nerds who want to understand what actually works in cold-weather homes.

Each episode breaks down the real building science behind blown-in insulation—cellulose, fiberglass, mineral wool, and how they stack up against spray foam—through the lens of Northeast and Connecticut homes. We go beyond sales claims and internet myths to explain how insulation performs in the real world: moisture, air leakage, R-values, installation quality, comfort, durability, and long-term cost.

Drawing from decades of hands-on experience insulating homes in Connecticut’s harsh winters and humid summers, this podcast connects theory to job-site reality. You’ll learn what matters, what doesn’t, and how smart insulation decisions can lower energy bills, improve comfort, and protect your home for the long haul.

If you care about building science—but want it explained clearly, honestly, and without the fluff—this is the deep dive you’ve been looking for.
