Tile Has Higher Thermal Conductivity Than Carpet

Wool carpet had a higher insulation value than com parable carpets of other fibre types.

Tile has higher thermal conductivity than carpet.

Carpet ranks very highly i e. So it makes sense that the specific heat of the carpet is lower meaning it will heat up really fast when you step on it making it feel warmer than the tile which has a higher specific heat meaning it takes longer for it to warm up when you step on it and therefor feels cold. The thermal conductivity normally found in tables is the value valid for normal room temperature. Heat conductivity is all about the rate at which the material can conduct heat.

Thermal conductivity explains why walking bare foot on a cold tile floor feels much cooler than walking on carpet even though both are at room temperature. Thermal conductivity of the material. The best type of flooring to use with underfloor heating is tile and stone. As can be seen from the table the thermal resistance of carpet is significantly higher than that of concrete and plywood two common flooring materials and similar to fiberglass insulation.

Tile and stone also retain heat well making the system efficient. However because marble tiles are usually twice as thick as ceramic tiles they offer greater protection against thermal conductivity. Specific heat has to do with how much energy is needed to raise an object s temperature. Carpet particularly wool and shag varieties provides the best r values among all standard flooring choices.

It simply has a higher conductivity and density and thus removes more heat from your relatively warm body more rapidly. Pvc tile has only 1 3 of the insulation of wool carpet. Pvc tile has only 1 3 of the insulation of wool carpet. Car pet r anks very highl y i e.

Simply put tile is the better conductor of heat than wood or carpet and can take away the heat from your feet faster than the others. When high temperatures are involved in ovens for instance the influence of temperature has to be taken into account. The thermal insulation values r values of different household materials are compared in figure 1. This value will not differ much between 273 and 343 k 0 70 c.

Of carpet with its millions of tiny fibres traps air and further increases its thermal insulation. Wool carpet had a higher insulation value than comparable carpets of other fibre types. Thus any statement that tile is one of the coldest floor materials is quite simply a misconception. Tiles feel warmer than carpet when the floor is hot.
