Heavy or not, fiberglass ladders are subject to suddenly melting.
Wood is twice as expensive -- about $100 per foot -- and about 15 percent heavier than aluminum or fiberglass, but it holds up better in a fire, said Mike Braun, supervisor of San Francisco's Fire Shop.
"Aluminum or fiberglass, when it gets too hot, it gets soft; it will actually fold over without any warning," he said. "Wood takes hours to fail completely -- enough time for a firefighter to see it burning and get off it."
That article contradicts the video clip on aging. It states three years, not 15.
