The AeroBarrier system uses an aerosolized sealant solution to eliminate any cracks or holes in a building’s envelope, even those not visible to the eye. The system can be used to meet LEED, ZERH, and passive house requirements, as well as the 2015 IECC or better. Users may adjust the application process in real time to achieve the results desired.

AeroBarrier’s waterborne acrylic sealant is Greenguard Gold certified, low-VOC, and tested to meet various ASTM standards for fire spread, smoke production, antifungal properties, and tensile strength. It is ideally applied at rough-in or post-drywall, and is third-party certified to withstand a 50-year durability test. aerobarrier.net

Air King

The QuFRESH by Air King Fresh Air Machine provides a constant supply of fresh air from outside the home, allowing builders to meet requirements for residential fresh airflow. Installers can set the precise airflow desired from 40 to 120 cfm for the unit’s quiet, energy-efficient fan system, and adjust intake levels for outside humidity and temperature. This prevents the introduction of outdoor air that is too humid or dry, or too hot or cold.

The unit may be mounted at any convenient point in the home, such as the attic, garage, or laundry room, with the proper duct and power connections. It is ASHRAE 62.2 compliant, as well as HVI Certified and ETL listed. airkinglimited.com
