For those who have had their Attic filled with blown insulation

[CorCentral]

Questions.......

1-- Your home's square footage?
2-- How much did the total installation cost? (cost+materials)
3-- How much do save per mth on your Energy Bill after you added the extra insulation?


I have a 2000sq foot home that cannot hold the HEAT! I have decent windows and the crawlspace is insulated.

HEAT LEAKS in the winter and COLD is DISSIPATED in the summer! It's a 1972 home. I can take pics of the attic later if it would help........... I have some blown insulation in there but it looks light. Sure does'nt seem like it's doing the job.

I have a 2001 house that's 2400 sq. ft. The insulation was supposed to be R30, but was so poorly done I'd say it was more like R20. I had it brought up to R49. The cost was $1200. Quite a lot of roof

I'll have to wait through the whole season to give you some idea about energy savings, but I can say that the inside of the house is much more comfortable and the furnace doesn't cycle near as much.

My next energy project is to get the duct work sealed with Aeroseal.

double paned low e glass?

It works well. I like to have a non-paper R-19 (or higher) fiberglass on the bottom and then blown insulation on top to get it to the mid 30's to low 40's in R-Factor. The fiberglass is easy to work around and if you put a hole int eh ceiling for work or even damage it will keep the blown from falling in to badly.

How thick is yours right now in inchs?

I have blown insulation in most of my attic, except where I have a solid floor (which shows the highest amount of heat loss). I also have rolls of fiberglass on top of the blown insulation. Last year I noticed that I was losing a ton of heat from my cathedral ceiling walls, which shared space with the attic. Those were R-19. I ended up stapling another R-19 around it and it's been much happier ever since.

Blown fiberglass or cellulose? I just finished insulating my house with dense pack cellulose. A bag cost me around $5 ($7-$8 at Depot or Lowes) If you wanted to add 6" (R-19), the chart says you will need 23 bags per 1000sqft

The insulation almost comes up to the top of the ceiling joists. It measures about 5"
Here's a pic of the Insulation that's up there.

Just single pane windows, but there's an extra sliding (storm window) behind the main window.

If you can afford it hard setting foam insulation works better than anything else.

5" is no where near enough. You better get blowing

I had more insulation blown into my attic last spring, and the difference is night and day. Before, the living room and hallway to the bedrooms were much hotter during the day. You could literally feel the heat radiating off the ceiling in the hallway. I went from about R-8 to R-30, and for 1600sqft. it cost me about $800 on paper but the state of Texas gave the installer a rebate so my total cost was $572. So far I've saved anywhere from 30-50% on my monthly electric bills, which is awesome. The house temp is much more stable now, and my HVAC actually cycles normally rather than being on for hours at a time.

Let me know the bid for that, will you? I am looking at something similar for late spring.
