QUESTION FROM JOHN: 

Can I pour insulation into my walls from the enterior directly against my exterior stone walls. My house is 140 years old and is constructed of 18 inch thick stone walls. The only option is to insulate from the inside. My thoughts were to drill holes and blow in from the inside. The stone wall does not have a vapour barrier so the insulation would drop between the slats and the stone. Is this a good option?
 

ANSWER FROM THE INSULATION DOCTOR:
   I would not recommend blowing from the inside if the insulation is going to come into direct contact with the exterior stone.  The insulation most likely would absorb moisture over a period of time from the stone.  If the insulation is not going to come in direct contact with the exterior stone, it would be a feasible idea.
 
Your other option may be to contact a company, such as Gale Insulation (a National company), and have them install foam insulation.  Foam has a high R-value and would act as a vapor barrier when hardened.
