If you live in an apartment or condo that was not designed for sound attenuation, then you know how annoying it is when you can hear your upstairs neighbor walking around, when their stereo speakers are blaring, or when something drops on the floor. Simply stated, that’s impact sound transmission.




Norton CST with insulation  

Even when the cavity between the floor and ceiling is insulated, one of the transmission spots is over the floor joist. This is a direct path between the floor and the ceiling.

NORTON CST®  dramatically reduces impact sound transmission through the joist.
