The Wrights relax in their den. The renovation called for new insulation that allowed the house to use smaller heating and cooling systems. Hartman air-sealed the floor and insulated the walls, ceilings and ducts with a dual layer of foam and cellulose, the latter of which was made of recycled newspapers treated with inert fire retardant. To maintain the period feel of the home's three bathrooms, the toilets are replicas of 1921 commodes that are also low-flow designs, from Bathroom Machineries in Murphys, Calif. The water fixtures are low-flow retro models manufactured by St. Thomas Creations.
