Blown-In Insulation to Prevent Attic Mold  

Published on March 23, 2020

Given the right conditions, attic mold can grow and thrive very quickly. In fact, in a high moisture environment, mold finds a very comfortable home. That’s why the attic and roof are so perfect for mold to reproduce.

With a proper installation, and the right type of ventilation, blown-in insulation contributes to a low moisture environment in the attic. When the attic is well insulated and ventilated there’s far less chance for mold growth.

The best approach with mold is prevention – but situations arise where mold is suspected or discovered. This is a good time to seek professional help, where the mold outbreak can be professionally inspected and removed.

Blown-in Insulation & Attic Mold

When properly installed, attic insulation can be integral in preventing mold growth. In the attic and roof cavity, insulation regulates temperature and moisture, which contribute to a dry environment that ‘s not hospitable to mold.

Blown-in insulation (along with air sealing) is key for controlling moisture. In wintertime, condensation is prevented, and in summertime moisture accumulation is averted. With the appropriate ventilation, the attic is in good shape. 

Mold Prevention in the Attic Space

The primary objective with mold prevention is to eliminate sources of moisture. And while there are countless insulation products, the important thing is to ensure an attic space that is sealed and ventilated. This is the way to keep air moisture under control.

Attic mold will not thrive without moisture to feed on. That’s why professional insulation contractors always recommend sealing the attic appropriately. Add to that good ventilation, and the installed insulation will do the rest – a clean, dry, ventilated space.

Insulation - Air Sealing - Ventilation

There’s no question that the attic has to be insulated AND sealed AND ventilated. Beyond the performance benefits, this is also the best way to prevent attic mold from establishing. When the attic operates as a “system”, homeowners benefit from better energy efficiency, lower utility bills, and improved indoor comfort.

Air sealing and ventilation improves airflow in the attic. This prevents excess moisture from accumulating, while keeping temperatures controlled in summer and winter. The fact is – insulation, sealing, and ventilation work together to ensure peak performance. It’s not good enough to just load up the attic with insulation.
