Another Insulation Thread


I am slowly working towards insulating and fixing the ductwork and parts of the walls around my place (a condo unit whose basement is primary made out of concrete block, and the first and seconds floors out of bricks). There are lots of lapses, gaps, and opening in the aluminum ductwork (the place was reformed and remodeled, but the jobs in many ways wasn't well done at all...) and parts on the upper portion of the walls whereon one can even feel air stream. Trying to use ductwork sealant compound/putty to fill small irregularities and crevices and aluminum foil tape, and also a combination of fiberglass ductwork insulation (the one that is wrapped around the ductwork) and reflectix over it in order to create a double layer of insulation (not sure how much improvement one could get out of that setup).

Ductwork sealant filling irregularities and crevices:

Old thin fiberglass ductwork insulation and new reflectix insulation applied to ductwork:

Fiberglass, Reflectix and Great Stuff foam combined on uninsulated part of walls:

New fiberglass ductwork insulation (thick one) applied on ductwork, and I am considering adding an extra layer of insulation on top of it with reflectix:

Any help and comments would be appreciated.
