I guess it would depend on how long the person planed to live in the house. I would imagine it would be cheaper then tear the walls out and re-insulating with rolled or foam insulation and re-sheetrocking.Joel_BC said:I'm in Canada and I've got a house that holds heat - not built that long ago and has good insulation. There's no doubt it would be a good investment, for the long run - if the resident could afford the up-front investment.chickenjoe said:How old is the house. If it 60 years or older you probably have little to no insulation in the house. I would see if you can get someone that does energy audit. Have them use a thremal camera to see if it is insulated. Then you would have to do blown insulation. You might be able to get one for free rom the gas and electric co. What it cost you to get it done will save you in the long run.
If you live where there are natural gas hookup. It might be worth you wild to change to NG furnance. I wouldn'y switch to LP it would be about the same as oil.
But I've heard for a long time about adding blown-in insulation with older frame houses. It's always sounded like a pretty good option, from a technical standpoint. I wonder, though, how much it tends to cost? Like for, say, a 1500sq ft house. $500/month, as mentioned in the subject line of this thread, could easily add up to $1000-2000 spent on heating in a winter. The decision to blow-in insulation would have to take into account the investment versus the likely savings.
I just did a calculation from this website http://www.homewyse.com/services/cost_to_install_blown-in_wall_insulation.html
for 1500 sqft it came out to about $5,000, so if even cut your heating bill in half or 1/3 it would till be good investment. To recoop what you spent, would take around 5 years.
