Ceramic tile, wood, and linoleum are fairly good conductors of heat and do not present any special design considerations. But carpet requires more temperature from below to force the heat through the carpet and into the room. This need for higher temperatures below the floor will likely require improved insulation underneath everything to prevent heat loss downward.
Follow these rules of thumb:
- Avoid carpeting high heat loss areas such as mudrooms and entryways.
- For structures that are reasonably energy efficient, 3/4 inch carpeting over a 1/4 inch pad is acceptable.
- In low heat loss areas such as the second story of a well insulated structure, carpet may be used.
