Open cell spray foam vs Rockwool for whole home
I’m building a new home and currently at the insulation stage.
The walls studs are 2x6 so I can fit 5.5in of insulation. My main concern is noise since there are a lot of barking dogs down the road.
I have the two options below and not sure which would be best to use for all the exterior walls. Keep in mind that the rooms also have two double paned vinyl windows. There seems to be a lot of articles that say open cell and Rockwool are basically the same sound wise, or Rockwool is slightly better. What do you guys think?
Sucraseal SES open-cell spray foam 5.5in
- product page said it’s sound absorbing (don’t know to what extent)
- cheaper and readily available
- well regarded for sound absorbing
- more expensive, less of an air seal, can only ship in at least 3 weeks
