Joe Arrigo, the Building Science Leader for Owens Corning, visits “Green is Good” to discuss the iconic building materials company’s new eco-projects. Owens Corning is the original manufacturer of Fiberglas, the insulation material used in millions of homes worldwide. Arrigo points out that Fiberglas pays for itself 12 times over in the first year following installation. Now the company’s Energy Complete system, launched in 2009, is leading the energy-efficiency and insulation industries. “On average, [Owens Corning] saves the homeowner 30% [on energy costs],” Arrigo reveals. “Domestically, energy costs are probably going to significantly go up in the near future, and we want to make sure that we’re making buildings more efficient.”
