    Why Your House Is Still Drafty After New Windows

    Your house is still drafty after new windows, and the glass is rarely to blame. Here's where the cold air is really getting in.Learn why the chill across your ankles is often a fake draft off cold glass, how the stack effect turns your home into a chimney, and why 1 recessed can light can leak 9 CFM50 into your attic. We break down the top plate gap that equals a window left open 4 to 5 inches all winter, how leaky ducts and closed bedroom doors pull cold air through your walls, and the attic-first air sealing order to follow before you replace another window.Nealon Insulation has kept Connecticut homes warm since 1977.

    How to Insulate Old Walls Without Wrecking the Plaster

    Insulate your old plaster walls the wrong way and you can rot the framing—or send hundreds of pounds of plaster crashing to the floor. Pre-1950s homes hide empty wall cavities that bleed heat through a constant convective loop. This episode breaks down the fix: why dense pack cellulose packed to 3.5 lbs per cubic foot is the gold standard for historic walls, cutting cavity air leakage up to 90% and reaching R-13 in a 2x4 wall. You'll learn the "knuckle tap" test that keeps your plaster from pillowing off the lath, why burying live knob-and-tube wiring is a fire hazard, how insulating without air sealing is a sweater with no windbreaker, and why the right retrofit can trim heating bills 30-50%.

    Ice Dams in Connecticut: Why Your Warm Attic Is the Culprit

    Ice dams aren't a roof problem — they start in your warm attic. Here's why Connecticut homeowners get them every winter and how to stop them for good. We break down the physics: a foot of snow acts like an R10–R15 blanket, your warm attic melts it from below, and it refreezes into a wall of ice at your cold eaves. You'll hear why your gutters are innocent, why hacking at the ice with a hammer or running electric heat cables only makes it worse, and the 3-step permanent fix — air sealing, R-49 to R-60 attic insulation, and balanced ventilation. Plus the weird pantyhose-and-calcium-chloride trick for emergency relief (never rock salt). Brought to you by Nealon Insulation, Connecticut's trusted insulation contractor since 1977.

    Why Is My House So Hot Upstairs? The Building Science Behind It

    Why does your upstairs always feel 10 degrees hotter than the rest of your house, even when your air conditioner is running nonstop? In this episode of the Nealon Insulation Podcast, we break down the building science behind one of the most common homeowner complaints. You'll learn why the problem often has little to do with your air conditioner and everything to do with airflow, air sealing, attic insulation, ventilation, and how your home actually works as a complete system. We also cover common mistakes homeowners make, like closing supply vents or installing a larger AC unit, and explain why those "solutions" can actually make the problem worse. If you've ever wondered why your second floor never seems comfortable during the summer, this episode will help you understand the real cause and the best ways to fix it. If you're in Connecticut and struggling with a hot upstairs, Nealon Insulation can help.

    Ceiling Insulation: The Science of Insulation in Connecticut Homes

    In this episode, we take a deep dive into ceiling insulation and why it plays such a critical role in cold-climate homes, especially in Connecticut. From winter heat loss and the stack effect to attic moisture, mold, ice dams, and building code requirements, we break down the science behind keeping homes warmer, safer, and more energy efficient. We’ll explore Connecticut’s current insulation standards, including R-60 attic requirements, the importance of proper air sealing, and why even the best insulation can fail if hidden ceiling bypasses are left unsealed. The episode also covers common insulation materials like cellulose, fiberglass, spray foam, and rigid foam, along with the differences between vented attics, unvented roof systems, and cathedral ceiling assemblies. Before any insulation project begins, safety matters. We also discuss key hazards such as active knob-and-tube wiring, asbestos-containing vermiculite, mold, and roof leaks that can delay or prevent weatherization work. Whether you’re a homeowner, contractor, energy auditor, or building professional, this episode explains what really matters above the ceiling: controlling heat, air, and moisture to create a more durable and efficient building envelope.

    Beneath Your Feet: The Ultimate Guide to Crawl Space Insulation and Encapsulation

    That dark, musty area beneath your floorboards is easy to ignore, but what if it was secretly costing you money, affecting your home's air quality, and making your living spaces uncomfortable? In this episode, we pull back the curtain on the most neglected part of your home: the crawl space.We dive deep into the fundamental shift in building science—from the traditional "vented" approach to modern "encapsulation". Learn why up to 60% of the air you breathe indoors originates in your crawl space due to the "stack effect," and why failing to manage moisture below can lead to mold, wood rot, and structural damage.In this episode, we discuss: The Vented vs. Unvented Debate: Why traditional vents often do more harm than good by inviting humid summer air into your foundation.The Insulation Material Showdown: We break down the pros and cons of common materials.What is Encapsulation? We walk through the process of "shrink-wrapping" your crawl space with heavy-duty vapor barriers, sealing vents, and adding active humidity control with dehumidifiers.Energy Savings and Home Value: Discover how proper crawl space management can save you an average of 15–20% on heating and cooling costs and increase your property value by up to 10%.Critical Safety and Code Checks: From termite inspection gaps to fire-rating requirements and radon mitigation, we cover what you need to know to ensure your project is up to code.Whether you’re dealing with cold floors in the winter or a persistent musty smell in the summer, this episode provides the technical analysis and expert tips needed to turn your "damp dungeon" into a clean, controlled part of your home

    Garage Insulation 101: Materials, Moisture, and What Actually Works

    Garages are the most misunderstood space in your home. They’re not quite inside, not quite outside—and if you get the insulation wrong, you feel it everywhere else. In this episode, we break down garage insulation from the ground up—without the fluff. We start with what building codes actually require (and why attached garages are treated differently), then dig into the real-world consequences: cold floors above, condensation dripping off doors, and energy bills creeping higher than they should. From there, we get practical. You’ll hear a clear comparison of insulation materials—spray foam, fiberglass, cellulose, and mineral wool—so you can match the right system to your garage, whether it’s heated, attached, or just storing tools and cars. We also cover hybrid approaches like “flash and batt,” and when they make sense. Moisture control gets special attention, because that’s where most garages fail. We walk through simple, proven fixes—from ventilation and vapor barriers to low-cost hacks that stop winter condensation in its tracks. Finally, we zoom out and talk ROI: how insulating your garage creates a thermal buffer, reduces HVAC strain, and improves comfort in the rooms you actually live in. If you’ve ever wondered why the room above your garage is freezing—or whether insulating your garage is worth it—this episode gives you the answers, grounded in building science and field-tested experience.
