Question by Kevin: Would Perlite insulation be a good choice to insulate house walls?
My house has no insulation in the walls. Would perlite insulation be a good choice to fill the walls through a hole in the sheetrock at the top?
Thanks

your in the states ..im in the uk if your stud walls are constructed the same way as-ours then it wont work ..we have a horizontal timber mid-span …called a noggin …this would prevent the insulation getting past the half-way point ..i would be surprised if you did not have a noggin as it strengthens the wall and makes it more rigid

Depends on how your house is framed. If your house is a typical vertical wood frame construction, you can have blown-in insulation put in between each stud. I have never heard of perlite being used as insulation, but it sounds quite interesting. Perlite is a low density type of glass, so it should behave the same as fiberglass I would imagine.
I would talk to a reputable insulation specialist about the R- value of perlite before you decide to use it though. A more common blown-in insulation would be cellulose based.
If it has the same R- value of the cellulose and is cost effective, then hey go for it.
