spray insulation or fiber glass batts?

Wondering if I should get spray on insulation, closed cell, in a new cabin. Have heard some health concerns over the year but not sure what is or isn't true. Any input would be great.

Not opposed to installing fiberglass. Have swam in my fair share over the past 30 something years and it doesn't bother me or send me into a scratching frenzy.

Any reason not to use mineral wool?

Each has it's own pro's and con's. Spray foam offers some of the highest R value per inch and is generally a vapor and air passage barrier but it is expensive. So, most homes are still built using fiberglass or some other more traditional insulation.

Spray foam is superior but it MUST be covered.
It is not flameproof and cannot be left exposed in the living area.

I would never hesitate to spray foam my home if I could afford it.

Stickshift, I have a enough left over rolls of faced fiberglass from another diy project.

PJ, when you say covered do you mean sheetrock? What other materials would you cover with?


Got one bid for spray, about $5 per square foot, seems way high according to a quick google search.

Spray foaming is very expensive. There is a reason the other insulations are still more popular.
