A simple vent for equalizing the temperature between two rooms without allowing people to walk between them.
- 1 ˣ 1
A vent conducts some of the temperature from one room to another room. It structurally acts like a wall to separate rooms and it supports a roof. Placement of a vent requires open space on its two sides (no solid structures such as walls). The blueprint can be laid atop an existing wall; the wall is replaced upon construction. The placement of multiple vents along a wall increases the temperate transference. Requires the Complex Furniture research to build.
