Shane lives in Burien, WA. He's wondering about putting rigid foam on his house. He's also not sure about house wrap.

"Can I put rigid foam on the exterior of my house and does the house wrap go on top of the foam or under the foam?"

Shane, you can put rigid foam as an exterior sheathing over wall studs. You need to make sure the walls have diagonal bracing. opens in a new windowCLICK HERE to watch a video I did about it.

House wrap goes over the foam. Think of it as a gift wrap over a box.
