Insulating interior and exterior of block wall

Steve Mattera| Posted inGeneral Questionson

Hi folks,

I have a block wall foundation in northern Vermont. The exterior (below grade) is faced with 2″ rigid insulation all the way to the footing.

The inside of the walls are not insulated at all. And I have plenty of extra foil faced 2″ rigid left over from a previous project. So I am thinking of using it to cover the inside walls too, and air seal their joints. I am thinking of fastening to the wall using adhesive only (PL or liquid nails).

Overall, anything else I should consider ahead of time or be aware of?

Thanks, Steve
