Cellulose Blown-In Insulation Helps Control Moisture/Mold/Mildew Inside the Home

Cellulose blown-in insulation can play a significant role in moisture control inside the home by helping to manage and regulate indoor humidity levels. Here's how cellulose blown-in insulation contributes to moisture control:

Hygroscopic Properties: Cellulose insulation has hygroscopic properties, meaning it can absorb and release moisture without compromising its insulating effectiveness. This helps regulate indoor humidity by absorbing excess moisture when humidity levels are high and releasing it when conditions are drier.

Moisture Absorption and Redistribution: If moisture enters your home due to leaks, condensation, or other factors, cellulose insulation can absorb and distribute the moisture. This prevents moisture from pooling in one area and potentially causing damage.

Capillary Action: Cellulose insulation utilizes capillary action to draw moisture away from damp surfaces. This action helps to distribute the moisture more evenly, allowing it to evaporate gradually rather than leading to the formation of concentrated wet spots.

Air Sealing and Vapor Retarder Qualities: When cellulose insulation is properly installed, it creates a more airtight building envelope. This reduces the movement of humid air from the interior to the exterior or vice versa. Additionally, some cellulose insulation products are treated with vapor-retardant additives, which can help prevent the passage of excessive moisture vapor through the insulation.

Preventing Condensation: Cellulose blown-in insulation fills gaps and voids in walls, ceilings, and attics. By doing so, it helps prevent warm, moist air from coming into contact with cold surfaces, which could lead to condensation.

Long-Term Moisture Management: Cellulose blown-in insulation is not prone to settling over time, which means it will continue to provide effective insulation and moisture control for the life of the insulation. Settling can create voids where moisture could accumulate, so this property is important for maintaining long-term moisture management.

Sound Installation Practices: Proper installation is key to maximizing the moisture control benefits of cellulose blown-in insulation. It's essential to hire experienced professionals who know how to install the insulation correctly, ensuring that there are no gaps, voids, or compressed areas that could compromise its performance.

It's important to note that while cellulose insulation can help with moisture control, proper installation and maintenance are key. Incorrect installation can lead to gaps or settling that might compromise its effectiveness.
