$8,000 for a 200-year green door?

From an article in today’s San Francisco Chronicle entitled, “Not enough green for green living,”

… “So how much do [the eco-friendly windows] cost?” I asked, while Barry gave me an overview of the various windows that she sells, often at trade shows on green building.

“A lot,” Barry said in her lilting South African accent, demonstrating how one particular brand of window makes a complete seal when closed.

“OK, how much?”

“Well, like this big sliding glass door costs $8,000,” she said, slowly sliding a massive glass and wood door shut. One can buy a cheap door in similar dimensions at Home Depot for $500.” I raised my eyebrow.

“The wood is Forest Stewardship Council certified,” she added. “It was made to last 200 years!”
