                                                           Note the joist hanger
                                                           for the 4-by-10 floor
                                                           beam. It was held in
                                                           place by only two nails,
                                                           and was nailed into the
                                                           end grain of a lami-

        This 4-by-10 inch floor beam is supported by a   DIY
        field-fabricated sheet metal, fashioned into a   Hanger?        Over    This is the family room insulation, or lack thereof. No
        joist hanger. Note that only two nails were driven                      wonder this 3,050-square-foot house required eight tons
        into the beam. We are retrofitting to correct this                      of air conditioning. Crews removed all of the roof framing,
        defect.                                                                 and replaced it with a 12-foot-high ceiling with a flat roof.
                                                                                The above-roof-deck insulation includes four inches of
                                                                                DuPont extruded polystyrene, along with a closed-cell
                                                                                spray foamed roof with a reflective spray-on membrane.




























  Amateur        Can you believe the poor quality of insulating work behind the
     Hour?       walls of this luxury custom home? This is the family room rear
                 wall. In 2013, a 2-by-8 wall was built to allow the installation of a
                 16-foot stacking door. They applied the R-13 batt fiberglass with
                 haphazard effort and inconsistent results.
