Floor system

Wooden sound insulation floor system

Measures against noise from upper floor

Sound insulation board (Tiger Super Hard)

[Features]

Excellent fire resistance
“Hard-type gypsum board(Tiger Super Hard) 12.5mm thick” is applied to plywood boards to provide quasi-fire resistance performance.
Superb sound insulation performance
The sound insulation of floors can be improved depending on the type of building and the performance level demand.
Easy to control the process of work due to the advantage of dry construction system
Because it is using dry construction system that is focused on the usage of “sound insulation board”, it will save effort and time such as construction management and drying period, which will result in shorter construction time.

Wooden floor system with self leveling material

SL Plaster is the gypsum based self-leveling flooring material, which is premixed at our high quality plants and can be installed quickly.

Self-leveling subfloor materials (SL Plasters)

[Features]

High-performance self-leveling assures finely evened surfaces just by flowing to floors and leveling with suitable tools.
Thanks to properties of gypsum, no need to worry about shrinkage cracks, as excellent adhesion to the base surface can be expected from these products.
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 by applying suitable base treatment.
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 floor vibrations.
