Vinyl siding melting on homes in Twin Cities suburbs

Sunlight reflecting off neighbors' energy-efficient windows may be causing vinyl home siding to melt in the Twin Cities suburbs reports Lora Pabst for the Star Tribune. Pabst cites Kerry Haglund (Center for Sustainable Building Research) as saying "the high temperatures could be caused by several factors within the window manufacturing process, including a coating that is meant to increase the reflection. Window industry experts are working on adjustments that could be a solution." A comment on the Star Tribune article reveals evidence from a glass manufacturer (.pdf; 139KB) indicating that the Vinyl Siding Institute has been aware of the potential problem since February 2002.
