Underfloor air duct heating method is an advanced heating system considering an efficient heating performance, health, and safety, which minimizes environmental burden in the construction process and contributes to the suppression of climate changes due to global warming.

The concrete generally used in construction sites uses 245kg of cement per 1m³, and the CO2 discharged in the process accounts for 8% of the overall emission. Cement production process, which heats limestone at high temperature, generates massive CO2, 44% of the mass of limestone, and accounts for a significant part of the total greenhouse gas emission.

However, this method does not reclaim radiant media like before, which does not require autoclaved lightweight concrete and cement mortar deposit, and eliminates power consumption during production and CO2 generation caused by cement used in construction sites, reducing greenhouse gas.

Modern improvement of Korea’s traditional ondol (heating device) succeeds to the traditionality of ondol heating for pride, and if exported, it can promote the excellence of ondol globally. Overseas branches will see an increased sales through royalty.
