Lowtech Graph lists low-tech options for every need of a home. Here you can compare them, find tutorials to build them, and link them together into a circular system. Why low-tech?
Fire-rated compartmentalization
Passive
One of 2 ways to meet this need. Cost, carbon, footprint and rankings are relative to other solutions for the same need, not absolute.
Fire-rated internal walls/doors slowing spread and preserving an escape route.
Matches wall/door assembly lifespan (fire rating is a material/assembly property, not a wearing part); fire-rated door seals/intumescent strips typically need inspection every 1-5 years
Levels are relative to the other options for this need, not absolute. Fewer dots is lighter.
Fire-rated compartmentalization (This page) Can I use it? Works in a flat · No rebuilding needed What does it cost me? Upfront cost: Medium · Skill to build: Basic · Upkeep: Light · Change to daily life: None · Works without the grid: Yes Choose it if you want to slow a fire inside the house and keep an escape route open.
Defensible space / vegetation management Can I use it? Works in a flat · No rebuilding needed What does it cost me? Upfront cost: Low · Skill to build: Basic · Upkeep: Light · Change to daily life: None · Works without the grid: Yes Choose it if you want to stop a wildfire reaching the house through the land around it.
We don’t list sizing or quantities, as the yield of each technique depends on the quality of its build. The catalogue compares options but doesn’t dimension them. Regulatory notes are indicative, with a French example, and need to be confirmed locally.
