Currently remodeling a 1965 vintage colonial in New England with fiberglass batte insulation. The house feels very drafty. Can Icynene insulation be injected into outside wall cavities to add additional insulation as well as seal the house, or do I have to rip out the old fiberglass battes? What are other alternatives for sealing house as well as increasing insulation?

Tosh , All of the icynene I have seen applied has been spray-on app.
*I recall reading somewhere that they had a new product that could be injected into wall cavities(as opposed to surface spraying) but I wasn't sure what the success rate was with this type of application. Thanks, though, for your input
*I believe they do have an injectable foam, but you already have fiberglass in your wall cavities. Adding the foam might blow out your walls, so you'd need to remove the FG first.did
