Having well-insulated walls is essential for keeping a reasonable humidity level inside your home. The insulation acts as a barrier, preventing issues like mold growth, condensation buildup, structural damage and musty odors. Ultimately, it contributes to the creation of healthy and affordable living spaces that safeguard your house and well-being.
Problems With Excess Humidity
A house with too much humidity can make it difficult to relax or entertain. Dust mites, mold and mildew all thrive in environments with high amounts of moisture. The molds emit harmful gases that can induce nausea.
The high humidity can cause problems with wood building materials and furniture, like warping, cracking and weakening over time. Too much moisture can also lead to rust and corrosion on metal surfaces and building components. Condensation may form on walls and windows due to high humidity. This dampness has the potential to deteriorate structural elements, wallpaper and paint over time.
Problems With Too Little Humidity
Low humidity levels can cause just as many problems as excess moisture. The lack of humidity often results in dry skin, itchy eyes and sometimes respiratory issues. If you have allergies or asthma, you might notice your symptoms get worse when there is low indoor humidity.
The dry conditions may shrink or crack wooden furniture and building materials. They may also increase static electricity, which can damage electronics.
Homes with a lack of moisture tend to feel colder than they really are. This causes homeowners to use their heaters more, which can skyrocket heating costs.
The Role of Insulation
Insulation prevents the transfer of heat and moisture by forming a physical barrier. It keeps the living conditions stable by lowering the evaporation rate and the relative humidity. Let’s take a closer look at the benefits of insulation for better indoor humidity control.
Reduces Moisture Infiltration
Insulation helps regulate interior humidity in many ways, one of the most important being the decrease in moisture intrusion from the outside. Inadequate insulation lets outside air moisture in, which is particularly problematic in humid climates. When water from the outside seeps into your home, it increases the relative humidity inside. The best way to keep excessive moisture out of your house is to insulate its walls, attic and flooring. This is especially helpful during the rainy season or in areas where the external humidity stays high.
Minimizes Condensation
When warm, humid air comes into contact with cold surfaces, such as windows, pipes or outside walls, condensation forms. This buildup can cause major problems like water damage, mold growth and structural deterioration. Insulation keeps the air in your house at a constant temperature, greatly reducing the likelihood of condensation. Over time, the reduction in condensation will help prevent problems like peeling paint, wood rot and mold growth.
Enhances HVAC Efficiency
Indoor humidity plays a large role in the overall efficiency of your heating and cooling equipment. In the summer, excessive moisture can significantly impact AC performance by making it work harder and decreasing its cooling efficiency. If ignored and the humidity increases to over 60%, it can even freeze the coils. In the winter, a lack of humidity will make the heater overwork and cause dry air. If you don’t address the issue, you might notice problems like dry skin, static electricity and cracked furniture. Adding insulation to your home will help with these issues by maintaining stable indoor humidity. Most importantly, it will boost HVAC efficiency for longer-lasting equipment and cheaper energy costs.
Balances Indoor Air Quality
Improving indoor air quality is one of the best things about adding insulation to your home. As we already mentioned, homes that lack insulation often experience problems with drafts and temperature fluctuations; this results in poor air quality that increases allergy and asthma symptoms. With the right type of insulation, your home will enjoy fewer drafts, more consistent temperatures, less mold and mildew and better air quality.
Best Types of Insulation for Indoor Humidity Control
You have several insulation types to choose from to achieve better humidity control. Understanding the different kinds will help you make the best choice for your home.
Spray Foam Insulation (Closed-Cell)
Closed-cell spray foam insulation forms an airtight (and watertight) seal to prevent moisture infiltration. It acts as both an insulator and a vapor barrier. A lot of homes add it to basements and crawl spaces. Its excellent thermal resistance also makes it ideal for places like attics.
Rigid Foam Board Insulation
Rigid foam board is another type that has really good thermal insulation. It works well for decreasing condensation buildup on walls and in basements. You can combine it with vapor barriers for added protection.
Fiberglass Insulation With Vapor Barrier
Homes with basements or crawl spaces often benefit from fiberglass insulation with a vapor barrier. The barrier stops water from penetrating the ceiling and walls. This type of insulation is popular among homeowners because it is both economical and effective. Like most other forms of insulation, it does require professional installation to achieve the best performance.
Mineral Wool (Rock Wool) Insulation
Mineral wool insulation is not only resistant to moisture but also fire. This makes it great for homes that are in areas prone to wildfires. The insulation does not absorb water, so it won’t become a breeding ground for mold or mildew. Because of its noise-canceling qualities, it is ideal for homes located in busy or noisy environments.
Cellulose Insulation (Dense-Packed)
Dense-packed cellulose insulation minimizes humidity imbalances by decreasing the passage of air and moisture. Chemical treatments can make this type of insulation resistant to bugs and mold. It is a sustainable choice that uses recycled materials.
Insulation Tips for Better Moisture Control
If you want to use insulation for better moisture control, it’s almost always best to use one with a vapor barrier. This will protect the home against mold growth and water damage. It will also translate into improved energy efficiency, which can help with reducing heating and cooling costs.
Another important tip is to seal all gaps and cracks around windows, doors and ducts. This will minimize moisture infiltration, making it easier for your HVAC system to maintain consistent temperatures. To seal these gaps and cracks, it’s best to use spray foam or caulk.
You need to prioritize insulating your attic, crawl areas and basement. These are the places that tend to experience the most moisture buildup. Insulating them will prevent water damage and help provide better temperature control.
Here are a few bonus tips you can use to achieve the best insulation possible in each part of your home. For the attic, always remember to add proper ventilation and ensure the insulation covers all gaps. In the basement, insulate the walls, and seal any foundation cracks. For crawl spaces, it’s best to insulate the floor and walls so that moisture doesn’t enter the living areas above. Hiring a professional for the job will guarantee the best sealing possible.
