How to insulate between floors for sound.

One thing is certain. Major insulation manufacturers including certainteed johns manville knauf fiber glass and owens corning market 3 1 2 inch thick fiberglass or rock wool acoustic batts specifically for sound control. Essentially all these approaches to dealing with noise coming from upstairs involve a process known as soundproofing. We recommend using 100mm of acoustic floor insulation and a density of between 60kg m 80kg m to increase the soundproofing between floors.

Using felt underlayment insulating between joists and installing a floating floor are some of the ways sound can be reduced within a house.
