Re: Insulation Cost Analysis
* Bring attic insulation to R-60
* Insulate kneewall flats with R-30
* Blown cellulose into exterior walls
These would be the main areas with equal importance.
* Insulate basement walls
This will add benefit as well though the basement will maintain a somewhat constant temperature in the 50's to low 60's degree on it's own.
However .... it does definitely help to insulate the basement walls in preventing heat loss from the basement and cold infiltration through the basement walls.
* Insulate basement ceiling
In my opinion this returns little benefit since warm air rises which is advantageous for the upper floor.
One area that is critical is the perimeter rim of the floor where it sits on the foundation. Insulation at this area definitely needs to be applied.
Sounds as though you have an older home that is balloon framed?
If the exterior walls have no insulation, is it possible to blow insulation up the cavities from the basement (instead of going from the outside)? I have access to the cavities from the basement.
If so if there is knob and tube wiring present you will need to have this addressed since it can't be covered over with insulation.
You will need to discuss this with an insulation contractor .... I think it would be tricky to do it that way because of gravity.
Another area to mention is the heating equipment.
Without discussing the efficiency of the equipment itself but rather improving the delivery of heat from the system.
If you have forced air heat sealing the duct work and insulating them will improve the efficiency.
With hot water piping would likely benefit from insulating the pipes.
Just some thoughts.
