Eliminate the Mold Risk
How a closed attic system air seals your home and eliminates mold risk
A closed attic system is one of the most effective ways to improve your home's energy efficiency, eliminate moisture issues, and protect your attic from mold growth. At Ultimate Insulation, we specialize in transforming attics into airtight, well insulated spaces that help homeowners in cold climates save money and prevent structural damage.
How a Closed Attic Air Seals Your Home
In traditional vented attic systems, outdoor air continuously moves through soffit and roof vents, making the attic highly susceptible to temperature fluctuations and moisture buildup. These systems also allow warm indoor air to escape through leaks in the ceiling, leading to higher energy bills and ice dam formation in the winter.
A closed attic system, on the other hand, seals the attic from outside air by applying closed cell 2lb. Polyurethane high-performance spray foam insulation to the underside of the roof deck. This effectively brings the attic inside the home's conditioned space, creating a continuous air barrier that prevents leaks, drafts, and temperature swings.
Benefits of an Air-Sealed Attic:
- Prevents Heat Loss - Keeps warm air inside during winter, reducing heating costs.
- Stops Drafts - No more cold air seeping into living spaces through attic access points.
- Improves HVAC Efficiency - Heating and cooling systemswork less, saving energy.
- Better Indoor Air Quality - Prevents attic dust, pollen, and pollutants from entering the home.
How a Closed Attic Eliminates Mold Risk
One of the biggest issues with vented attics in cold climates is the potential for moisture buildup and mold growth. Here's why:
- Warm, humid air from the home rises into a vented attic.
- When this air meets the cold surfaces of the roof deck, it condenses into water droplets.
- Over time, this trapped moisture leads to mold growth, wood rot, and structural damage.
Because a closed attic system eliminates air leakage, it prevents warm indoor air from reaching cold attic surfaces, removing the conditions that allow condensation and mold to form.
How a Sealed Attic Stops Mold:
- No More Air Leaks - Prevents moisture-laden air from reaching cold surfaces.
- Consistent Temperatures - No extreme cold surfaces where condensation can form.
- No Need for Ventilation - Eliminates reliance on airflow to manage moisture.
- Protects Wood & Insulation - Keeps attic materials dry and mold-free.
Long-Term Protection for Your Home
By air sealing your attic with a closed system, you're not just improving energy efficiency-you're safeguarding your home against mold, moisture damage, and costly repairs. At Ultimate Insulation, we help homeowners create airtight, efficient attics that stand up to extreme cold and keep their homes warm, dry, and healthy.
