Re: Sound deadening and Insulation Materials
Just a reminder that water can get down in the doors/windows which may affect the insulation's performance.. We found a factory installed substance like roofing mastic for sound deadener in our car doors and that could be another alternative but probably won't have the insulating value with modern insulation. We also found weep holes in the floors (to channel water from town sedan rear operable windows) which could be blocked by insulation.
