Yes, I'd like to try a titanium hammer. No, I don't have money to spend on one. So your offer sounds great.

I am remodeling our small old house with Passivhaus standards in mind. I plan to use closed cell spray foam to maximum the R-value in our 2x4 walls (plus sheet foam on the exterior). I too am concerned about "gluing" wires and pipes into the cavities. I'm toying with ideas of using a kind of conduit that can be standardized in the walls for future changes. Plastic pipe run horizontally at approximately 16" and 48" high would allow for standard outlet/switch levels. Plastic pipe could be cut into to access the channel. This would probably work best in conjunction with 2x2 horizontal firring strips on the interior of the 2x4 walls. I'm also looking at the readily available flex conduit in a large enough size to allow future wire fishing.

Any thoughts or suggestions?
