Green Technology

Philadelphia is a city of row houses ... unfortunately many are in blighted condition and when they are town down the newly  created "end units" are poorly insulated.  Cleaning up the blighted homes causes the other homeowners to have basically little or no insulation on a large surface of their home.

"In the interest of creating local green jobs, the city hopes to find a local manufacturer." " ... product consists of layers of insulating foam (for thermal protection), high-density foam (to absorb impact), fabric (to prevent penetration of sharp objects), and a latex-stucco finish.  ... produce it in 2-by-4-foot panels that will be affixed to a wall with a foaming adhesive."

" ... Philadelphia University's help was enlisted after the city determined that existing exterior-wrap products were too expensive and not sufficiently durable."
