I currently have gold fiberglass, paperbacked insulation under my first floor/ on basement ceiling. (Between the joists of course) I was considering replacing it with rigid styrofoam board (blue or pink) insulation for a cleaner more attractive appearance that can even be painted. i realize this wouldnt be cheap and there would be a lot of cutting involved, and then a lot of sealing up gaps with foam spray and such. I was wondering how good the insulating properties would be as well as the sound insulation properties. Could the styrofoam insulation perform better than the fiberglass bats i have now? I'm also not sure what thickness I would need to do the duties of the fiberglass. The fiberglass is about 6" thick. What are the potential positives or negatives i could gain from the installation? Rigid Styrofoam 2" thick is not going to give you the R value that 6" of fiberglass insulation has = R 19. However it will look a little better. It will be expensive as a 4' x 8' sheet of 2" Dow styrofoam is about $20.
You will have a lot of cutting to do also.
Sometimes there is not an easy way to make a basement ceiling look good. You could install a suspended grid ceiling but as you know there are lots of pipes,ductwork,wires to go around - some of them will still remain below the ceiling.
If you have the money and the time - go ahead with the styrofoam and yes you can paint it - black ceilings make the ceiling disappear. Paint all the pipes,ductwork first with black spray paint, Then paint all the styrofoam panels before cutting and fitting between the joist - touch up the cut edges after it is installed.
Record some measurements to help you later find any valves,ductwork boots (floor register boxes for upstairs) and other things you may need to locate, then you will only need to remove certain styrofoam panels to get to these important locations.
You already know and have thought about this a lot, So go with your instincts. If i could see it - I could tell you what I would do.
Good LuckYou would have to be extremely careful in removing the fiberglass insulation - unless it is completely encapsulated. The formaldehyde in it as well as the fiberglass, of course, are hazardous to your health.
You might want to ask your electric company to do an energy audit to see if you could do anything to save energy - and ask what they think of your idea.
Also, an insulation contractor or home inspector may be able to advise you more specifically.

Hope this helps. Don't do it. Exposed foam is a fire hazard, and as an insulation, it's far more expensive. I bet drywall is more sound-deadening, too, just because it's more dense. I'm not sure I can see any potential positives to this proposed project, and I'm sure it violates safety standards and building codes.#If you have any other info about this subject , Please add it free.# |
