How to insulate a floor or ceiling

Why do we need floor insulation?
Floors in buildings are magnets for sound and heat to travel through. This can cause long-term issues for tenants and owners, such as nuisance noise, high energy bills and colder living conditions.

Installing floor insulation can improve energy efficiency – and reduce unwanted noise levels from spaces above by up to eight times.

ROCKWOOL Safe'n'Sound® is a stone wool batt insulation designed for interior wall partitions, floors, and ceilings for wood and steel frame construction where superior fire resistance and acoustical performance is required, resulting in an impressive thermal performance that prevents heat escaping through floor and ceiling spaces.

The new 6” Safe’n’Sound® is designed specifically for sound dampening to help prevent noise travelling from one floor to the next providing the peace & quiet you desire.

Can it be left open on ceiling like that? Or something must be put on it to protect stuff/particles falling down?

When they put this in my ceiling bits and prices fell off and made my floor very dirty

As a voice actor, an acoustically isolated recording environment is essential to recording pristine voice-overs and narratives. The voice booth in which I record was custom designed and constructed using ROCKWOOL Safe 'n' Sound in the walls, floors, and ceiling. After considering other acoustical insulation products, Safe 'n' Sound proved to be the superior option for my voice booth, and if I were to insulate walls and floors within a structure for sound isolation, I'd again choose ROCKWOOL Safe 'n' Sound.

Is this good for insulating for a split level 3 story townhouse with varying temps in different floors on different seasons like hot in 3rd floor and cold basement or spray foam is?

Is the 6" available to the public? HD and Lowes only has the 3".

I want to insulate to gable ends in the attic with Rockwool R-22 insulation. There are no vertical studs except the flat studs of the roof truss. also the are a lot of framing & siding nails which can't be cut to put new 2X6 studs. I live in Wilmington, NC & my attic get get up to around 120 degrees in the summer time & about 30 degrees in the winter. My question is: can I use a little construction adhesive to help hold the insulation in place?

This does not help with sound proofing my ceiling at all. I can still hear Everything going on upstairs

We know how to cut it we not about the fire enough tells how to use it ... make a play list

Wished Rockwool was tested for Cargo Conversion Trailer I'm thinking just another way to get more out there instead of pink board that all use for insulation, this is what I wanted to use but talking to Rockwool they said it was tested for those Situations,
More people are building their own camper out of Cargo Trailer because the quality is way better then some $20, $30, an more in cost, plus just getting what one wants an not what others what to sell to you
Have u seen the insulation that those manufacturers give u some real slap carp
An im not saying to sell to them because that will raise the cost to the customer an most likely be done like shit because its all about profits an selling to the customer an letting them profit from a great product like this
I've worked in power plant an lagged plenty of Boilers an ductwork using Rockwool an there's nothing like it when it comes from holding heat in
Maybe my next build I'll or we'll have this option when it comes to insulating our Cargo Conversion Trailer
