Phase Two Pre-Drywall Inspection

Last Friday, I had the phase two framing inspection.  There were five items documented.
  • Less than 10’ separation between master bedroom air supply and air return vents.
  • Less than 10’ separation between living room air supply and return air vents.
My main concern is the air supply would return before the perimeter of the room is heated or cooled.  Ideally the air supply would been on the opposite side of the room.  The site supervisor will have the HVAC supervisor investigate and verify the design.
  • Fixed glass window is broken at side living room wall.
  • Steel straps loose and displaced at three truss web connections above left side of entry hallway ceiling.
Easy fixes.
  • Water heater combustion air vent tubes are drawing air from “vent-less” attic space – vents may be needed in closet exterior wall instead of ceiling.
Some new contruction has been done with so called ventless roof systems installed. This is where a contractor sprays an insulation product on the underside of the deck of the roof in between all the rafter spaces.
