| | Radiant sheathing, foil faced OSB panels (Oxterminator), is installed on the west wall that will have a brick veneer. It provides an exterior vapor barrier, drainage plane and radiant barrier all in one. |
| | Foil faced roof decking provides radiant barrier to reduce heat gain to the 2nd story vented attic. |
| | | Seams of foil-faced OSB sheathing are taped with foil tape to seal against water (for drainage plane) and air infiltration (exterior air barrier). |
| | The shiny side of the radiant barrier roof decking faces down so it faces the vented air space. The foil is perforated to allow any moisture to escape. |
