Moisture Management

The average household creates 4-6 gallons of water vapor inside every day through activities like cooking, showering, and cleaning. When adding insulation, the home’s shell becomes tighter and less leaky.

Although tightening a house helps to improve the energy-efficiency of a home, it is important to make sure water vapor inside the home is still able to escape to the outside. When moisture is not allowed to escape, it can lead to problems like mold, mildew, or sick home syndrome. Here are some possible symptoms.

• Sneezing, runny or stuffy nose, cough & postnasal drip, itchy eyes, nose, and throat, watery eyes, hoarseness, headache, skin irritation.
• Can also trigger asthma symptoms like: coughing, wheezing, shortness of breath, tight chest.

TriWall’s insulation component features a permeability rating up to 3.5, allowing moisture from inside the home to move freely to the outside.

In addition, TriWall features built-in moisture management grooves in the insulation to provide an extra layer of defense. If rain or bulk water makes its way behind the insulation, the built-in grooves channel moisture down and away from the wall, helping to eliminate the potential for moisture damage.

Third party drainage efficiency testing performed by the Home Innovation Research Labs proved that TriWall’s built-in drainage plane drained 95% of moisture from the wall within the first 30 minutes. Within 90 minutes, 99% of moisture had drained from the wall.
