The current FHB has a story on economical and energy efficient buliding. In the article a picture shows that the exterior of the house was covered in 1″ solid foam, BEFORE sheathing, with plywood placed over the insulation at the corners for structual strength. Could the entire house be covered with plywood sheathing in order to avoid having to run strapping for clapboards (in the article, vinyl siding was used. Shudder.)? In other words, could I sheathe my house first with foam, then with plywood? I like the thought because the plywood could provide support for the windows and save me the strapping time (time is an enourmous issue for me), as well as keeping the foam hidden from ants. My concern is that the plywood might want to sag, although the house will be a Cape with only one high side. Any thoughts?
Brian Pontolilo demonstrates how to air-seal where the concrete foundation, mudsill, and ZIP System sheathing all meet.
