Sound insulation wall that can be gapped

A-2000・WI - Gapped spec

S12・WI - Gapped spec

Hyper Wall Z・WI - Gapped spec [TLD-52]

A-2000・WI Joiner gapped system

[Features]

When buildings are deformed due to strong winds, earthquakes, etc., it may cause cloth or paint finishing of the fire resistant sound insulation wall inside to crack at the seams of gypsum board. By making the top layer of the surface material to be gapped, it will reduce the occurrence of these kind of cracks, and also reduce after-maintenance.

[Applications]

Places where sound insulation performance is required and easily dislocated such as “staircase hall”, “upper parts of doors”, “T-shaped intersecting parts” etc.

*1 In case the gap width is 10mm (at least 0.12g per 1mm of gap width)

*2 If there is any space between the PVC hat-shaped joiner and the top lining material (Tiger Hyper Hard C w/9.5mm thickness), the indicated sound insulation performance will not be achieved.

* When creating a gap (a watermark)at internal corners, be sure to use “Jizai-Meji-Hatto-6 ” for the gap between top layer boards for the overfill. Since the angle of flanges on "Jizai-Meji-Hatto-6" is changeable, it can be used as a panel joiner for the gap between top layer boards.

・Material: PVC plastic

・Dimension: Outer width: 10(±1.0）mm or less
Flange: 21（±2.1）mm
Height: 5（±0.5）mm
Thickness: 0.5（±0.1） to 1.0（±0.1）mm

○he total length of gaps on both sides should be no more than 5.46m per 10.05㎡ of wall area.

* When constructing this wall structure, it is possible to combine boards having the fire-resistance certification number of FP060NP-0389（2） and FP060NP-0390（2), and it is possible to make it into a wall with both butt joints and gaps.

＜A-2000・WI Joiner gapped system (crack and sound insulation measures for cloth in wall corner perimeters)＞
�Patented (Patent no.5663119)

When buildings are deformed due to strong winds, earthquakes, etc., it may cause cloth or finishing materials on perimeters (corners) of dry separation walls to crack at the seams of gypsum board. This system can reduce the occurence of cracks and also prevent the reduction of sound insulation performance in dry separation walls.

Description of “A-2000・WI Joiner gapped system”

* Uses dedicated joiner “Product name: Tiger Joiner S3” (PVC).

* Gaps (width: 10mm or less) are made between the top surface material (Tiger Super Hard 9.5mm thick) and the structural framework (2 sides: A side and B side shown in the front view), and dedicated joiners are inserted. Dedicated joiners are fixed with adhesives to prevent any space between the structural framework and the top surface material (Tiger Super Hard 9.5mm thick).

* Sound insulation performance:TLD-55

Dedicated joiner shape illustration	* If there is any space between the dedicated joiner and the structural framework, or between the dedicated joiner and the top surface material (Tiger Super Hard 9.5mm thick), it will not achieve the indicated sound insulation performance. * For more details, please refer to the Standard Instruction Manuals for Construction Works.
