Re: Home Heating Survey (4.00 / 2)

I am really surprised by the apparent lack of modern insulation in buildings in so many of the residences reflected in this diary. We've had two houses here near Wash DC since the mid 70s and both have had R14 insulated walls, R32 ceilings and double glazed windows (triple and exotic filled also available). These standards are common. I suppose one reason is that it's easy to build and insulate our tinderboxes.

Re: Home Heating Survey (none / 1)

Your R ratings:

Your wall insulation is far above what code was in the area until the 1990s, I beieve.
Recommended R for the area is R-19 walls and R-45 in the attic

And, I would expect that the vast majority of existing homes in the area do not come close to these levels.

Re: Home Heating Survey (4.00 / 2)

Yes, I was a little off. The 70s structure was R11 all exterior walls, R33 attic.

Our 1994-95 constructed (and current house) is R30 attic, R19 overhangs, R13 exterior walls, R11 unfinished lower (basement) level. Windows are double pane thermal insulated. Looks like we could update our attic but exterior wall changes could be expensive due to lack of depth and requirement to remove siding or interior wall board.

All still a lot better than what I expected to be standard in other parts of the world.

Much better than mine and, well, I face the very expensive to upgrade existing walls. (Easy are all done.) I might pull out the R19 in the one crawl space, spray foam an inch (R-7, plus near 100% leak proof) and put the fiberglass back up.
