Once your humidity levels are back under control, you’ll notice a decrease in energy spending related to home heating and cooling.Īs the Bay Area heads into the cooler and moister winter season, ensure your home is ready for it by taking proactive measures to enhance insulation and moisture control. As a result, elevated interior moisture and humidity levels cause your HVAC system to work harder to meet the demands of your thermostat. Increase energy efficiencyĭamp makes hotter temperatures feel hotter and cooler temperatures feel colder. Reducing interior humidity levels to within that span has multiple benefits. If you are due for your annual HVAC maintenance appointment, ask the technician to test your humidity levels for you. You can purchase a humidity testing device online or at your local hardware store. So, what’s the big idea about a little indoor humidity from time to time? The experts agree that ideal interior humidity levels are between 35% and 50%. 3 Reasons To Use Vapor barriers To Reduce Interior Moisture Levels

Always make sure you’re working with a licensed contractor before deciding to install vapor barriers so you can trust their judgment. When they are not needed or if a vapor barrier is installed incorrectly, they wind up causing moisture issues. Here is the problem with vapor barriers: when they are needed, they make a difference. In addition, if interior humidity, mold, or window condensation has been an issue in the past, you may notice these situations improve as well. Once vapor retardants are in place, you’ll notice a distinct difference in reducing HVAC demands, which directly translates to utility savings. If you know you have bare earth and there is no vapor barrier in place, it’s time to contact an insulation contractor and schedule an inspection. This can often lead to unpleasant smells and issues with temperature control over time. The damp soil within a crawlspace can often lead to cooler air rising through the house as well as odors making their way up into your property. For example, the ICC’s International Residential Codes Chapter 7 states:Įxposed earth in unvented crawl space foundations shall be covered with a continuous Class I vapor retarder in accordance with this code.Īny uninsulated crawlspace within your home or property can present a severe disadvantage for your cooling and heating system. Some building codes require vapor barriers for specific locations. In a warmer, humid climate, contractors typically apply vapor barriers to the exterior of the walls, underneath the siding, to mitigate moisture transfer that would seep from the exterior to the interior otherwise. However, in cooler, damper climates, we typically attach vapor barriers on the inside of exterior wall surfaces, mitigating the transfer of moisture that accumulates there via condensation - when the warmer interior air meets the cooler exterior surface of the walls. Therefore, there is no set standard as to how a vapor barrier is applied. The ultimate goal of a vapor barrier is to prevent moisture accumulation (condensation) from migrating to the home’s interior. Water-water resistant materials come in sheets and are installed as per manufacturers’ instructions. A vapor barrier is a kind of material that’s used to resist moisture from entering through the wall, ceiling, and even the floor. Vapor barriers, also called vapor retarders, can be used as part of a residential roofing system in conjunction with insulation inside exterior walls and crawl spaces with exposed earth. Vapor barriers work in tandem with insulation and ventilation systems to keep interior moisture levels to a minimum, enhancing whole-home comfort, energy efficiency, and air quality.

Poorly controlled moisture and indoor humidity levels lead to problems, ranging from condensation on the windows to structural rot and mold infestations. Our proximity to the ocean and cooler climates means Bay Area homes are vulnerable to moisture control issues.
