Materials that Improve the Cost‐Effectiveness of Air Barrier Systems

3M has developed a primer-less self-adhered membrane that serves as an air, liquid water, and water vapor barrier. This technology installs in up to half the time of asphalt-based membranes, which will lead to installed costs that are similar or lower than that of asphalt-based membranes.

Dow Chemical is developing a sprayable liquid flashing that serves as an air and liquid water sealant. This technology will have an installation time that is up to four times faster than that of peel and stick flashing tapes, while having a similar installed cost.
