The Hansen House Part 9: Insulation & Interior Systems

White PVC pipes run under the slab where the domestic hot and cold running water tubes are housed and run.  These plumbing tubes are part of the Hansen House’s wet wall, a structural wall designed to house plumbing pipes for fixtures like sinks, dishwashers, washing machines and toilets. Hansen_10-08-12_001 Hansen_12-14-12 063 The tubes are connected into the manifold and then distributed throughout the house to the designated fixture.  Consolidating plumbing in a single wall increases efficiency as well as cutting down on building costs. Hansen_12-14-12 024 Hansen_12-14-12 062 The black PEX tubes are for the radiant floor heat which also run to the manifold where the water will be heated by an electric water heater.  The PEX tubing was attached to the rebar which was laid out in a checkerboard pattern on top of the foundation’s 4″ of insulation.  Then concrete was poured to form the slab.

Hansen_10-08-12_005 After the plumbing tubes were all in place, the cellulose insulation could be sprayed.  Netting was installed on ceilings and walls to hold the blown in cellulose in place.  The netting was used so that the drywall would not have to be installed before the insulation was blown in, which could cause moisture problems. Hansen_12-14-12 012 Hansen_12-14-12 028 The windows and doors were covered with plastic to be protected during the spray insulation process.  Polyurethane, the yellowish material, was sprayed to seal any plywood seams to ensure a tight building envelope. Hansen_12-14-12 045 Hansen_12-14-12 043 Hansen_12-14-12 044 Because the insulation is blown in an excess of material tends to accumulate; therefore, while one person blows in the cellulose another person vacuums it up where it is sent back to the truck and recycled back through the process. Hansen_12-14-12 102 Hansen_12-14-12 105 The metal braces seen in the picture below are part of the t-bracing which prevents lateral movement.  Rigid foam was added to the cavity so that settling of the insulation was minimized and controlled.

The Hansen House Part 8: The Windows

The black tar paper around the window openings is for durability and to protect the window sills. Hansen_12-12-12 003 Hansen_12-12-12 002 As you can see below, the corners of the openings have water and ice shield for further protection. Hansen_12-14-12 001 The InLine Fiberglass windows are triple pane low-e casements with fold down cranks and colonial grids between the window panes. Hansen_12-12-12 004 Hansen_12-12-12 005 All of the windows in the Hansen House have white exteriors and Oak laminate interiors, except for the windows in the garage which have brownstone exteriors and Oak laminate interiors. DSC00467 DSC00469 Using the window orientation as a reference point to help determine where the sconce should go, our Project Manager had the great idea to put the sconce on a 2×4 and have the homeowner move it up and down the wall to help him visualize where he wanted it placed. Hansen_12-12-12 010 Hansen_12-12-12 013 These exterior shots show the timber framed side porch, without the roof on it yet, and the installed windows.  The Marvin Integrity Center Hinge French Doors with sliding screen are found on by the side porch and off of the front of the great room.
