Hello Lconover, welcome to the Community.


Re: installing foamboard insulation


There are two types of foamboard insulation each with different installation processes.  The first is Foamular extruded polystyrene rigid foam board.  This is applied to either wood or steel framework stud walls.

The second type is call Insulpink by Owens Corning basement wall insulation system.  No wall framing is necessary so you have minimum loss of space. 

There is no vapor retarder required with either product.

I have included installation instruction for both products, just click on the colored words and you can determine which will serve your needs the best.


If you have more question please ask.
