You might want to point out to Wifey how much money you saved, while at the same time preventing this type of material going to a landfill, an ecological no-no. Last week I picked up two 1"x2'x8' sheets of extruded foam, for my ongoing house reno project, at a nearby lumberyard, at a cost of $22.00 per sheet. Where did you say this house was?

At least I've finally decided to
not use extruded foam sheets for my upcoming second-level layout extension! Sheesh! (Maybe burl walnut, with ivory inlays.
