Thermal flywheel effect

The thermal flywheel effect, sometimes also referred to as "Thermal Momentum", is a term used to describe the property of a material to remain at a given temperature. It is generally applied to buildings or construction materials. This is distinct from a materials insulative value. A building's average internal temperature can stay stable much longer due to the thermal flywheel effect.

Materials, higher to lower "flywheel effect"

1. Packed Earth
2. Brick
3. Water
4. Hardwood lumber or timbers
5. Softwood & construction lumber
6. Steel
7. Insulation
8. Air
9. Aluminum

This is only a general classification, as the quantity (mass) and thermal conductivity, and arrangements of materials all have an effect on this.
