  • Environmental specifications for formaldehyde absorption test: Room temperature at 30℃, relative humidity at 50%, ventilation frequency 0.5 time/hour (in-house measurement), 6-mat tatami room, CLEARTONE 12S installation area rate 19%
  • Installation area rate: Installation area of the CLEARTONE 12S ceiling material divided by the entire surface area of room (including openings)
  • The measured test results in *1 are based on our laboratory measurement data and vary depending on installed furniture/interior equipment, temperature, airtightness, room size or plan, or other conditions.
