unvented
Lacking air outlets
Unvented describes something lacking a vent or opening for air, gas, or heat to escape.
An unvented gas fireplace releases combustion products directly into the room rather than through a chimney or flue.
Unvented attic spaces trap moisture and heat.
The word also applies figuratively to emotions not released: unvented frustrations.
