Interested in re-roofing your house? Or building a home and wondering what roofing system to go with? Check this out… Swedish company SolTech Energy has developed some cool-looking, award-winning solar glass roofing tiles. (Note: these are not active solar tiles but a passive solar roofing option.)
The glass tiles can be installed using traditional roof tile installation methods, and the tiles have a longer life than conventional concrete or clay roofing tiles.
How does the solar glass roofing system work? Preston Koerner of Jetson Green reports: “air below the glass tile is heated by the sun and redirected for use by the central heating system. The system works with air-based and water-based heating systems, including, for example, a ground source heat pump, air heat pump, pellet boiler, oil boiler, or electric boiler.”
The system is available commercially in Sweden and Spain and SolTech Energy intends to bring it to the U.S. in 2011.
The roof system is especially helpful in snowy climates since snow easily slides down the glassy tiles. The system won the Hottest New Materials 2010 award from the North Building Fair (aka Nordbygg).
