i have read through this thread: https://www.hearth.com/talk/threads/air-sealing-satisfaction.104200/ most of the outlet/switch reference seamed to be geared to new construction and what i deduced is that the foam seals under the covers are not worth it? is this true? my house gets hit with a lot of wind and now that we are heating with wood and keeping the house warmer i can really tell where the air infiltration is. number one is the front door which we are currently saving up to replace. number two seems to be exterior electrical boxes, especialy on the north side of the house that gets hit with the dominant cold wind. is it worth it to try to seal these? if so, what is the preffered method for walls that are sheetrocked already? house is 2400sqft with vaulted cielings in every room. 2x6 construction of 1989 that i think is insulated well. its just the air leaks that are bothing me. i plan to address better sealing the exterior in a few years when we replace the wood siding. thanks in advance.
