Thermal flywheel effect
From Wikipedia, the free encyclopedia
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"
- Packed Earth
- Brick
- Water
- Hardwood lumber or timbers
- Softwood & construction lumber
- Steel
- Insulation
- Air
- Aluminum
This is only a general classification, as the quantity (mass) and thermal conductivity, and arrangements of materials all have an effect on this.
