Protect the integrity of building materials without compromising schedules.

Polygon’s ExactAire® helps contractors gain visibility and control of the moisture content of materials like wood and concrete so they can deliver high-quality results on time.

Moisture management during construction has become more important as the height and area of buildings has increased. The larger and longer the project the more materials may be exposed to inclement weather or excessive moisture inside the building. In addition, moisture that gets trapped inside a building during construction can cause mold, mildew, or even structural failure. This is particularly important to mass timber projects where engineered wood products have strict moisture control requirements. Contractors follow manufacturer specifications to avoid issues and protect warranties. However, each project and location can have different conditions that can change over time. Using general guidelines or simple techniques like handheld devices can introduce risk to the product and schedule.

Continuously monitoring moisture content with the ExactAire Multi Sensor is an efficient and effective way to balance quality and speed. Not only will contractors know when moisture levels meet spec, but they will also have the information required to expedite dry times using integrated climate control solutions. For added security and autonomy, data can be piped to temporary climate control equipment that can automatically turn off and on depending on conditions.

“Polygon worked with us to set up a custom ExactAire system, online dashboard, and reporting process.  It provides important data on the exact conditions throughout the project, in our many different work areas and elevations.  We can see if there’s an issue right away, and based on the location of the sensor we can quickly hone in on the cause and get right to work on the solution.  We also have the history and trendlines, which provides assurance...It’s great to be able to show, without any question, that conditions are right...”
