Q: I know that knob-and-tube wiring can't be covered with insulation, but what about BX cable and joist-mounted junction boxes? Are there any restrictions on blowing cellulose insulation into an attic and burying the cable and junction boxes?
Q. Are there any code-approved sheathing materials for a garage under a living space other than the typical 5/8-inch drywall? My clients complain that drywall doesn't hold up well in our environment, so I'm wondering if fire-retardant plywood would be a good substitute if the joints are properly prepared.
