1st Floor is uninsulated
As in; down in basement look up at rafters, or joists, and the 6 inch deep space is bare
Except for 2 to 3 FT by the edge at Cement Walls
But it gets cold in here
Started putting up R19, but being told not to
Won't this slow the travel of heat in a room
If cold isn't right there to take it's place, then the heat would stay longer
It will reduce heat loss (some, altho ceilings are far more prone since
warm air rises, but conduction is still going on) from the room itself, yes.
Whether it's overall "win" for the house depends mostly on whether the
basement area is living space at all or not and where are the utilities,
water lines, etc., etc., located. If you remove existing stray heat
from an unheated area such as that, you _may_ introduce the ills of
freezing water lines or the like.
More details needed...
BTW, who said not to and why? Above like reasons by someone
knowledgeable of the situation and building in general???
Let see here
Regular Basement. Cement Walls, Water Pipes, Electrical, Phone and Cable Wi
res above, 2x6 flooring, plywood with oak floor above that
Electrical, Phone, and Cable Box on one back corner
Opposite corner has Boiler by Chimney
Mass Save guys came here, I asked and they told me not to insulate floor ca
use then the heat from basement will not get to 1st FL. I looked at the guy
and said what Heat? From the Boiler by a brick wall that supports the base
of a chimney at the side of house which is exposed to cold every winter
Only thing living in basement is the Rabbit
And stuff stored there
Yep...they're right in all likelihood that it's not a "win" for the house.
Insulate the outside barrier walls, etc., instead, and the basement
floor. See the link I posted elsewhere.
Since I'm making this response here, while it's again associated w/ the
attic instead I'll just add the other link I intended that has some nice
diagrams that may be of interest here instead of yet another post...

No insulation in typical basement ceilings here in the NYC area either,
including new construction, so it's obviously not a code reqt.
They do insulate around the rim joist. Ground temp is around 50F year
round, so you only have a 20F delta. I guess insulation would get you
something, at least in the winter. In the summer, it would keep the
50F basement from helping with a small amount of similar cooling effect
though. Sealing any drafts from openings, basement windows, etc would
probably get you more benefit.
If you don't use the basement in the winter, insulate the floors.
By "use" I mean you need it heated because you spend time down there.
Make sure the basement is warm enough that the pipes won't freeze.
And the rabbit doesn't die.
But, as noted in a follow-up upthread, this is likely a net "lose" for
the whole house as the boiler is in the basement and it contributing to
the heating of the house. Isolating that from the house by insulating
the floor will cut that off and require more heat from the actual
operation of the boiler to make it up.
Add throw rugs, etc., to take the cold feel off the floor itself.
Add insulation to basement, particularly as another noted to rim joists
and stop air infiltration is best bet financially on the actual insulation.
