This Old House - Season 24 - Eps 11: The Winchester House - 11
The Winchester kitchen addition is nearly complete, and general contractor Tom Silva installs the last of the new historically accurate double-hung windows on the sun porch. In the kitchen, mineral wool - an old-style insulation known for its fire resistance and sound deadening capabilities, now revamped for the residential market - is sprayed into the walls. Custom cabinetmaker Jeff Peavy lays out the design and material choices for the kitchen, and roofing contractor Tom Evarts shows master carpenter Norm Abram his crew's project: architectural asphalt for the main roof, and flat-seam lead-coated copper for the addition. Plumbing and heating expert Richard Trethewey shows host Steve Thomas the new plastic water supply lines, and the heating and cooling system, supplied by flexible 4"" ducts.
