What type of insulation should I use between floors?
Because they have a high R-value and can be used nearly anywhere in your home, foam board insulation is one of the most common types of insulation. Best for floors, foundation and basement walls, interior and exterior wall sheathing and low-sloped ceilings.
Should I insulate between 1st and 2nd floors?
Typically, insulation is used between a “heated” space and an “unheated” space. Between the 1st and 2nd floors – ultimately they will both be heated so insulation between them would be really useless. And, usually, the insulation is put in the attic, not in the ceiling.
Does insulation between floors help with sound?

It is possible to over-insulate your house so much that it can’t breathe. The whole point of home insulation is to tightly seal your home’s interior.

When soundproofing is your goal, your best options out there are fiberglass insulation and blown-in cellulose insulation. Both materials are incredibly good at their jobs; they insulate incredibly well but also have the coveted noise-reducing properties that many homeowners are seeking.
How do I reduce footstep noise from upstairs?
For noise that’s coming from upstairs, install a drop ceiling in your home. Use resilient channel, and invest in acoustical tile that’s designed to block noise. Because the drop ceiling is situated below the original drywall ceiling, the plenum space in between helps isolate noises from footsteps or similar sounds.
How do you dampen sounds between rooms?
Fabric placements: Drapes or wall hangings can help absorb sound and reduce transfer. Also add pillows to furniture — the more the better, so long as they do not get in the way.

Cellulose insulation primarily insulates air noises. In order to mute impact sounds as well, you should choose a thick insulation layer.
Should you insulate ceilings?
