How Much Moisture Is OK in Walls?
Excessive moisture in walls can lead to a number of problems, including mold growth, rot, and structural damage. The ideal moisture content for walls is between 10% and 15%. If the moisture content exceeds 20%, mold growth is likely to occur.
Venting and Fans for Moisture Control
There are a number of ways to reduce moisture levels in walls, including:
- Using a kitchen exhaust fan when cooking.
- Opening windows and doors to ventilate the kitchen.
- Installing a bathroom fan in the kitchen.
- Using a dehumidifier in the kitchen.
Kitchen Exhaust Fans
Kitchen exhaust fans are the most effective way to reduce moisture levels in the kitchen. They work by drawing air out of the kitchen and exhausting it outside. When choosing a kitchen exhaust fan, it is important to select one that is rated for the size of your kitchen.
Bathroom Fans
Bathroom fans can also help to reduce moisture levels in the kitchen. However, they are not as effective as kitchen exhaust fans because they do not draw air out of the kitchen. Instead, they simply recirculate air within the bathroom.
Dehumidifiers
Dehumidifiers are another option for reducing moisture levels in the kitchen. They work by removing moisture from the air. Dehumidifiers can be either portable or whole-house units. Portable dehumidifiers are typically used in smaller spaces, such as kitchens. Whole-house dehumidifiers are used to control moisture levels in the entire house.
