Floor Systems (Quasi-Fire Resistant and Sound Insulation Systems)


Floor systems using Tiger Super Hard (hard plasterboard) for wooden houses
[Features]
  • Excellent fire resistance (12.5 mm Tiger Super Hard is applied to plywood boards to provide quasi-fire resistance property)

  • Superb sound insulation (The sound insulation of floors can be improved depending on the intended use of the building and the performance levels to be attained)
  • Easy to control the process of work due to the advantage of dry construction (No requirements for construction management and drying period)


[Definition of Floor's Impact Sound Isolation Performance]
The performance of reducing floor impact sound (e.g. noises generated when heavy objects are dropped or children are jumping on floors) transmitting to lower level floors is called LH (Heavyweight floor impact sound level). To improve levels of impact sound isolation, total weight of floor systems needs be increased and floor structures must be strengthened to minimize deflection.

The performance of reducing floor impact sound (e.g. noises generated when dropping light objects such as coins or golf balls) transmitting to lower level floors is called LL (Lightweight floor impact sound level ). To improve levels of impact sound isolation, soft materials must be used as backing materials for floors.
*1) LH: Heavyweight floor impact sound level. (Tested at acoustic laboratories)
*2) LL: Lightweight floor impact sound level of floor and ceiling systems (Tested at acoustic laboratories)

[Recommended Floor Materials] (Floor Materials for Floor Systems on the Second Floor)



* All performance values were measured at the acoustic laboratory, therefore the same results may not be obtained in actual buildings.

Wooden Floor System using SL Plaster (Gypsum Base)
SL Plaster is the gypsum based self-leveling flooring material, which is premixed at our high quality plants and can be installed quickly.
[Features]
  • Excellent self-leveling
    High-performance self-leveling assures finely evened surfaces just by flowing to floors and leveling with suitable tools.
  • Free from shrinkage cracks
    Few shrinkage cracks occur due to gypsum's properties, thus excellent adhesion can be obtained. Ideal for repairing uneven surfaces caused by being exposed to rain
  • Quasi-fire resistance of up to 1 hour can be achieved when SL Plaster is installed at a thickness of 35 mm.
  • Excellent bonding strength between SL Plaster and plywood boards can be obtained provided any openings or gaps on surfaces are filled or sealed and any dirt is removed from surfaces prior to applying SL Plaster.
  • SL Plaster offers high strength joint less floors unlike in the case of using autoclaved lightweight concrete panels
  • Heavyweight impact sound can be isolated significantly as strengthened floor systems can reduce vibrations of floors.
