Drywall

Drywall is a decor-neutral, non-traversable building tile used to completely seal off tiles from gases and liquids while still appearing as a solid wall. It blocks movement, conduits, and most interactions through the tile but preserves the visual of a finished interior surface. Drywall is often used to isolate rooms, protect against hazardous atmospheres, or create airtight compartments without relying on natural terrain.

Drywall cannot be walked through and occupies the full tile as a construction object. It prevents gas and liquid exchange between adjacent tiles, making it functionally equivalent to a solid rock wall for the purposes of sealing biomes and maintaining separate atmospheres. Because it is a built building, it can be constructed in locations where natural rock is absent and is commonly used to close off areas after tunneling or to create controlled environmental chambers for farming, oxygen generation, or storage.

Practical usage and interactions:

• Drywall is used to create airtight compartments for atmosphere control, CO2 scrubbing, pressurized oxygen rooms, and to protect living quarters from vacuum or hazardous gases.
• It blocks liquid and gas flow completely; use Drywall when you require a reliable physical and atmospheric barrier.
• Drywall tiles are non-traversable and will stop duplicant movement unless ladders, tile replacements, or doorways are added; plan pathing and access before sealing rooms.
• Certain tiles that normally occupy the same space as Drywall (such as Mesh Tiles or Airflow Tiles) cannot be built simultaneously in the same cell. There is a construction sequencing exploit that can leave Mesh/Airflow tiles in place: build a ladder at the Drywall location, then queue a build order over the ladder. A duplicant will replace only the ladder and leave the Mesh/Airflow tile intact. This technique is useful when building in The Void or when you need flow-through tiles without exposing the compartment.
• Doors, airflow tiles, and other service tiles should be placed intentionally; adding an Airlock or regular Door to Drywall allows controlled movement while preserving compartment sealing when the door is closed.
• When making modifications to sealed spaces, deconstructing Drywall will expose the room to adjacent atmospheres. Plan decomissioning carefully if the room contains breathable air or liquids.

Design notes:

• Use Drywall to create stable rooms for Gas Pumps, Gas Filters, Electrolyzers, and other atmosphere-dependent machinery to maximize efficiency and safety.
• Combine Drywall with vents, gas bridges, and pressure management systems to route gases only where desired.
• Remember that Drywall is a building and can be deconstructed; incorporate redundant safety measures (alarm, manual doors) when sealing critical systems.
