When you think about insulation, you probably think of it during snowy January mornings and keeping the warmth inside your home. But here in Central New York, our insulation needs don’t take a vacation when the snow melts. In fact, from July through September, your home’s building envelope faces a different kind of challenge: heavy, sticky humidity.
If you’ve noticed a “musty” smell in your basement, a muggy feeling in your crawlspace, or heavy air in your attic, your insulation might not be helping, or worse, it might be hiding problems.
The Problem: When Insulation Traps Humidity
Many older homes were built with insulation that was designed solely to stop heat loss, without much thought given to moisture control. If your insulation is old, settled, or improperly installed, it can act like a sponge rather than a shield.
When warm, humid summer air infiltrates your home through tiny cracks and gaps, it inevitably meets cooler surfaces in your attic or basement. If your insulation isn’t paired with a virtually-airtight home, that moisture condenses, saturates your insulation, and creates the perfect environment for mold to thrive.
The Solution: Air Sealing + Proper Insulation
At Energy Savers, we approach home comfort as a system, not just a product. To truly control humidity, you need two things working together:
- Air Sealing: This is your first line of defense. By sealing the gaps around your rim joists, attic hatches, recessed lighting, and plumbing penetrations, we stop the humid outside air from sneaking in. If the air can’t get in, the moisture can’t settle.
- Strategically Installed Insulation: Once the air is sealed, we upgrade your insulation to prevent heat from transferring through the walls of your crawlspace and attic areas. For basements and crawlspaces, we often recommend closed-cell spray foam. It serves as both a powerful insulator and a vapor barrier, meaning it seals gaps and resists water vapor simultaneously.
Why This Matters for Your Summer Comfort
Upgrading your insulation and air sealing isn’t just about mold prevention; it’s about your day-to-day comfort and your wallet:
- Ease the Load on Your AC: When your home is properly sealed and insulated, your air conditioner doesn’t have to work overtime to dehumidify the air. This saves you money and helps your HVAC system last longer.
- Healthier Indoor Air: By stopping moisture buildup, you reduce the risk of mold growth, which is a major contributor to poor indoor air quality, allergies, and respiratory issues for your family.
- Year-Round Durability: A home that stays dry in the summer is a home that lasts longer. You’re protecting your structural wood, your drywall, and your belongings from rot and humidity damage.
