[Greenbuilding] Insulation

[Kathy Cochran]

I am getting ready to insulate the old 1940's house with blown-in cellulose.
The exterior is stucco.  I have been advised by ALL THREE stucco bidders
that the holes should be punched from the INSIDE, because they will NEVER be
invisible from the outside, but with spackle / plaster interior patching
they will be.  Just FYI.  If anyone has any other experience with this, and
any different results, I would be delighted to hear from you.

Regards to all,

Kathy of kathys_old_house at goldrush.com

I think 'best' is always situational.

That said, I like blown-in insulation for many exterior wall 
applications.  Crack filling and full coverage are two advantages.  
Batts are good for places where you aren't worrying about infiltration. 
  I suspect that both being cellulose they perform about the same when 
applied well.

I have often wondered if I could shred old clothes sufficiently to make 
blown-in insulation out of it.  Get all of Goodwill, Salvation Army, 
Rummage sale, leftovers and use it to again keep people warm.

Thank You Kindly,

Corwyn
