Polymer Roof Reduces Heat Inside and Out
Jun-01-15
Researchers have created a polymer roof material that will radiate heat to keep a building’s interior substantially cooler.Developed by a team from the University of Technology Sydney, the roofing material is made up of common polyesters that have been combined with silver to form a “polymer stack.” The material will radiate heat at infrared temperatures while also absorbing just three percent of incident sunlight, enabling it to reduce the heat inside a building and minimize the urban area heat-island effect.

Similair materials to reflect sunlight have been around for 35 yrs. i used roofing products that was relective and would stretch so as to not crack in temperature and other expansion and movement shiftinf of the building. It also bounded well to joints such as concrete steel joint. The problem was that most people including my brother thought it was too expensive. the would rather have constant leaking problems from the joints cracking requiring frequent repairs.
What is the price of the product? Warrenty? Does it stretch in hot and even freezing temperatures?
