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?

Thermal bridging elimination

Interrupts a localised conductive path that short-circuits the insulation. Distinct from insulation itself, which raises resistance across an area; this removes a bypass through it.

Solutions

• Continuous exterior insulation detailing: Insulation wrapped continuously around the outside of the frame, with no gaps where beams or posts pass through. Without breaks, heat has no easy path out throu
• Strapped straw external insulation (ITE paille sanglee): Straw bales fixed with straps against the outside of an existing wall, then rendered over. The bales wrap the old wall in thick insulation with very little fram
• Insulated slab edge and slab-to-wall thermal break: Insulation laid around the edge of the floor slab and under its outer strip when the house is built, with a break between the slab and the foundation wall. Heat
• Exterior slab-edge insulation (retrofit): The same cold path closed from outside on a house already standing. The perimeter is excavated to expose the slab edge, rigid insulation that does not mind mois
