Walls are impassable structures primarily used to create rooms.
Acquisition
Walls are built and repaired by colonists assigned to construct. Walls are constructed with 5 Stuff (Metallic/Woody/Stony, 50 for SMVs) and take 135 ticks (2.25 secs) to build.
Wall construction may sometimes fail and waste the materials, more often with lower construction skill.
Summary
Walls are impassible objects that block movement, line of sight, and line of fire. An area enclosed by stone walls, doors, or even Nutrient paste dispensers is considered a room, with its own temperature, cleanliness, beauty, wealth, and spaciousness stats separate from the surrounding environment. Other impassable objects, such as steles, power generators, collapsed thick mountain roof, and sculptures, do not count as walls for the purpose of creating a room.
Walls can also support roofing, up to 6 tiles away in all directions. If walls, columns, and all other supporting objects are removed, then the roof will collapse and injure pawns and objects below. A room completely covered by roof is considered enclosed, providing complete shelter from weather, nuclear fallout, manhunter packs, natural light, and temperature. A double-layer of wall provides improved temperature insulation compared to a single layer wall, however, three or more layers do not provide additional benefit. Walls aligned diagonally will provide weaker temperature and beauty insulation than vertical or horizontal aligned walls but still create rooms, with the added benefit of being able to melee attack through the diagonal cracks.
Power conduits can be constructed below a wall, negating the conduit's beauty penalty.
Walls also provide excellent cover from projectile attacks, blocking 75% of shots. Pawns behind a wall with an adjacent free space can "lean" around the wall to Shoot at enemies on the other side. Pawns can actually perform Melee attacks through diagonal walls, although they can not travel or Shoot through diagonal walls.
Special
Certain damage types are designed to deal more damage to impassible terrain, and to walls specifically:
- Walls take 8x damage from Bomb type damage; 4x from being an impassable, and 2x for being a wall
- Walls take 30x damage from Thump type damage; 15x from being an impassable, and 2x for being a wall
- Walls take 7.5x damage from Breach type damage; 10x from being impassable, but 0.75x for being a wall

Analysis
Walls, or natural rock, are practically essential to create rooms and defensive structures. It's certainly possible to create a room of doors or coolers, but that is just more expensive. As impassible structures, they are important when controling enemy flow and creating killboxes. Sapper and breach raids will explicitly try and break them, but other raiders will path around so long as any target can be reached.
Material choice
Wall materials each have their own advantages and disadvantages:
Wood
Wood is easily obtainable in a vast majority of biomes, and are the fastest wall to create. They are very helpful when first starting a Crashlanded scenario, and nearly essential for Lost Tribe and Naked Brutality starts. However, wood is flammable. Other than raiders lighting it on fire, a bad dry thunderstorm or conduit explosion could end up engulfing your entire base in flames. Especially by the time you get to using Electricity, you should replace wood with another material.
Stone
Stone is very plentiful, but very time consuming. In addition to actually creating the wall, cutting up stone blocks takes quite a bit of work. However, stone is a fairly hardy material, and is completely fire-proof. Strategically placed sections of stone walls will act as a "fire break" to limit the spread of a fire while your colonists fight it.
- Granite is the most durable wall material. Limestone is the 2nd most durable. Limestone and slate have no redeeming qualities as walls over granite, unless your biome happens to lack the harder stone.
- Marble walls give +1 beauty to a room and colonists looking at it. They are otherwise the least durable stone wall.
- Sandstone walls are the quickest stone wall to build, which can save a lot of time for large bases.
Metal
Steel isn't as durable as stone, but is much quicker to make. Steel may be a necessity in wood-scare biomes like the ice sheet. Steel walls are also flammable, unlike concrete and the actual steel item. Overall, it's useful as a quick installation when creating defensive fortifications.
Plasteel and Uranium are even bulkier than stone, but these materials shouldn't be wasted except on the most important of wall sections, like the entrance of a killbox.
Gold and Jade walls are more beautiful than regular walls, but are inferior to sculptures when increasing room stats.
