More insulation

Dear sir,
I am insulating my house. What do you use to seal the junction between the cement basement and the wood house? There is about a 1.5-2 inch over hang .Foam has been suggested.For your info. I have brought the attic up to R50, and added 1,75 in foam to the basement and R 30 to basement ceiling.

Hi,
You can use latex acrylic caulk or canned foam to seal the crack between the two.
