Does Concrete Radiate Heat

[+] A very modern and efficient type of flooring is concrete. It has the ability to absorb heat from direct sunlight, store the heat and release it slowly. The ability of concrete to absorb and store heat energy is called “thermal mass”.

Does concrete make your house hotter?

Overall your statement is untrue. In warmer climates concrete buildings, be they RCC or CBC, will tend to collect and retain more thermal energy than a wood-frame structure making them more expensive to cool. The opposite applies in colder climates where RCC and CBC structures are more costly to heat.

Is concrete a good heat insulator?

Although concrete is not a particularly good insulator, heat loss or gain through a concrete slab is unlikely to be as significant as heat transmission through above-ground parts of your home, such as windows and doors, which are directly exposed to cold air and sunlight.
