The tougher the standard,
the more the structure matters
Metainnotech develops floor impact sound
insulation structures that meet the strengthened standard
and supplies them to construction sites nationwide.
Under the housing construction standard revised in August 2023, both light and heavy impact sound must stay at or below 49 dB.
Structures once rated light grade 1 and heavy grade 3 fall to light grade 3 and heavy grade 4 under the new rules —
Metainnotech still achieves light grade 1 and heavy grade 3.
