At the Rubin Museum of Art, Tibetan art is preserved in a carefully controlled environment—one that requires elevated relative humidity (RH) levels to protect precious artifacts. This is no different than the care taken in cigar humidors, nurseries, or offices, where RH control supports comfort, health, and longevity.

Yet in most buildings, RH levels are artificially ramped down to reduce the risk of condensation and mold growth—not because it's optimal, but because conventional facades can’t handle moisture.

 Active-Wall™ and Portalwall™ change that.
Our system makes it possible to maintain healthy, comfortable RH levels without compromising building integrity. Whether it's for young children, the elderly, or anyone in between, our enclosure technology gives designers the freedom to create truly livable environments—without the fear of mold, moisture, or failure.
