These modular and rapidly deployable treatment units use ultra-efficient building envelope technology to moderate the temperature of the unit and simplify decontamination efforts – enabling safer and more comfortable conditions for health care workers and patients. Designed to overcome the challenges that traditional “soft-shell” facilities (tents) face, this hard-shell unit features improved thermal efficiency, super-insulation, a design that facilitates easy cleaning, and interior surfaces and fixtures constructed from “direct contact kill” anti-bacterial and/or anti-viral materials.
