Our Construction Material Division
has developed a front door with "AIRT" ventilation function
and started selling it through Cosmo Kinki Co., Ltd. "AIRT"
is a word coined from ventilation function (air) and good design
In recent years, condominiums have been built to be airtight, and when air pressure inside the home is less than the outside air pressure, it sometimes becomes difficult to open or close the front door. By utilizing the "AIRT" system, the condominium is effectively ventilated. It has passed the fire protection equipment (fire protecting door) evaluation test. As "AIRT" offers a comfortable living environment, we are expecting further expansion of demand.
