Understanding the Impact of Humidity  in Your Home

During the colder months, maintaining optimal humidity levels in your house is crucial to prevent the shrinkage of wood. In this post, we’ll explore why wood contracts in low humidity and the importance of keeping levels around 30%.

Humidity is the amount of water vapor in the air, and it affects both your comfort and the health of your home. Wood is a natural material that responds to changes in humidity by expanding or contracting. 

Humidity control is important for your home because it can prevent problems such as mold, mildew, condensation, rot, corrosion, and pests. These issues can damage your home’s structure, furniture, flooring, and appliances, as well as cause health problems for you and your family. According to the U.S. Environmental Protection Agency (EPA), the ideal indoor relative humidity is between 30% and 50% — and must be kept below 60%.

Wood contracts in low humidity because it loses moisture to the dry air. This causes the wood fibers to shrink and pull away from each other, creating gaps and cracks. Wood contraction can affect doors, windows, cabinets, floors, and furniture, making them loose, squeaky, or warped. To prevent wood contraction, you should try to maintain a consistent humidity level in your home, especially during the winter when the air is drier.

Keeping humidity levels around 30% is important for your comfort, health, and safety. A humidity level of 30% means that the air contains 30% of the maximum possible moisture that it could hold. This level is low enough to prevent mold growth and condensation, but high enough to prevent dryness and irritation of your skin, eyes, nose, and throat. A humidity level of 30% also helps preserve the quality and durability of your wood products.

Controlling Humidity in Your Home

There are various ways to control humidity in your house or new construction home. From using humidifiers and dehumidifiers to proper ventilation techniques, we’ll explore practical methods to ensure your home’s humidity stays within the ideal range for wood preservation.

Humidity is the amount of water vapor in the air. High humidity can cause problems such as mold, mildew, pests, and health issues. Ideally, the humidity level in your home should be between 30% and 50%. Here are some tips on how to control humidity in your home:

  • Use a dehumidifier to remove excess moisture from the air. You can choose a portable dehumidifier for a single room or a whole-house dehumidifier that connects to your HVAC system.
  • Turn up the air conditioner to cool and dry the air. Make sure your air conditioner is well-maintained and has a clean filter.
  • Install vent fans in kitchens and bathrooms to exhaust humid air outside. Run them while cooking, bathing, or drying clothes.
  • Seal air and duct leaks to prevent humid air from entering the house and reduce energy loss.
  • Select houseplants that absorb moisture from the air, such as Boston ferns, peace lilies, or orchids.
  • Open windows or doors when the outside air is drier than the inside air. This can help improve ventilation and airflow.

I hope these tips help you control the humidity in your home and make it more comfortable and healthy for you and your family.

Humidity Management in New Construction Homes

New construction homes offer advantages in humidity control compared to old, drafty homes. Humidity is the amount of water vapor in the air, and it can affect the comfort, health, and durability of your home. Too much humidity can cause mold, mildew, and rot, while too little humidity can cause dryness, cracking, and shrinking of wood. Therefore, maintaining stable humidity levels is important for preserving the longevity of your home’s wooden components, such as floors, cabinets, doors, and furniture.

Modern construction techniques contribute to maintaining stable humidity levels by using advanced building materials and improved insulation. For example, new construction homes often use moisture-resistant drywall, which prevents water vapor from penetrating the walls and causing damage. They also use vapor barriers, which are thin layers of plastic or metal that block moisture from entering or escaping the home. Additionally, new construction homes have better insulation, which reduces heat loss and gain, and helps regulate the indoor temperature and humidity.

Another advantage of new construction homes is that they often come with modern HVAC systems, which can control the humidity level of the home. HVAC stands for heating, ventilation, and air conditioning, and it is a system that provides heating and cooling to the home. HVAC systems can also dehumidify or humidify the air, depending on the season and the preference of the homeowner. By using a humidistat, which is a device that measures and controls the humidity level, the homeowner can set the desired humidity level for the home and let the HVAC system adjust accordingly.

In conclusion, new construction homes offer advantages in humidity control compared to old, drafty homes. By using advanced building materials, improved insulation, and modern HVAC systems, new construction homes can maintain stable humidity levels, which benefit the longevity of the home’s wooden components. This can also improve the comfort and health of the occupants, as well as the energy efficiency and value of the home.

There are plenty of options we can add to control too much humidity or too little humidity.
