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?
One of 2 ways to meet this need. Cost, carbon, footprint and rankings are relative to other solutions for the same need, not absolute.
Soft or porous finishes such as curtains, rugs, wall hangings and wood-fibre panels. They soak up sound instead of bouncing it back. Echo drops and noise carries less between rooms, alongside thick walls rather than instead of them.
Levels are relative to the other options for this need, not absolute. Fewer dots is lighter.
Absorptive interior finishes (textiles, wood-fibre panels) (This page) 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 less echo and less noise between rooms, with things you can add today.
Room layout separating noisy and quiet zones Can I use it? Works in a flat · No rebuilding needed What does it cost me? Upfront cost: Low · Skill to build: None · Upkeep: None · Change to daily life: None · Works without the grid: Yes Choose it if you are planning the layout and want quiet bedrooms at no cost.

Limitations of this page
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.
