Air sealing and good attic ventilation all go a long way in helping reduce the probability of moisture causing complications. The good news is that many of the moisture culprits can be easily addressed and economically fixed. You should take care of any of these problems before you think about installing radiant barrier, to make sure you’re setting yourself up for optimum results with minimum problems. If you live in an area that has consistently cold temperatures, it is imperative that you find these sources of air leakage and fix them immediately since prolonged cold temperatures can increase your chances of moisture occurring. Can-lights (recessed lights) and attic stairways are usually the worst culprits of air leakage, which carry warm moist air into the attic. What are the sources of moisture? Light fixtures, ceiling fans, bathroom fans, attic entry points, chimneys, and duct registers are the best places to start.
The key to avoiding moisture problems in your home is to eliminate the source of moisture – or warm-moist air. So, foil does not cause moisture, warm-moist air and cold surfaces meeting together causes moisture. Warm water vapor in your breath comes in contact with the cold glass and condenses (or converts) into the liquid form of water. An example of this is someone breathing on a cold window. Condensation occurs when relatively warm-moist air comes in contact with a colder surface. Water vapor is water that is basically suspended in the air. You have a gas (water vapor) changing into liquid form (water). To be proactive toward these potential problems, it’s important to keep your attic both cool and dry and that’s regardless if you use a radiant barrier or not.Ĭondensation is simply water changing its form. Probably the two scariest words to associate with your attic. Myth: Using a radiant barrier causes moisture problems that ultimately lead to mold and mildew.
