As the standard of living is becoming higher year-by-year, people
are more conscious on their living environment and its management.
Traffic Noise prevention is a good example of this. Our newly developed
sound absorbing panel, 'Hi silent' is an innovative sound-absorbing
product utilizing the unique characteristics of porous concrete.
Hi silent absorbing panel was first applied to 1996 technical evaluation
system contest hosted by the Construction Ministry of Japan and
was tested in various settings to meet the standard requirements.
In the following year on June 3,1997, hi silent sound absorbing
panel received a certified evaluation signed by construction minister.
We have added onto our list a product using the recycled glass cullet
in 2000. This product was officially recognized by Japan Environment
Association under the eco-mark (recycle) program.
