Abstract
According to SPI statistics, the roofing industry used 61 million pounds of SPF in 1995 and 35 million pound in 1990. This represents a 70% increase in 5 years. SPFD predicts SPF roofing applications will experience similar growth through the year 2000. Why is there such a dramatic increase? Sustainability may be the answer. Oak Ridge National Labs defines sustainable low slope roofing as a "roofing system that addresses the issues of energy efficiency, use of materials with a lower environmental impact and embodied energy, durability with less maintenance, andreduced waste generation throughout the life cycle from design, through construction and reroofing, to reuse and final disposal. This presentation addresses each of these features as it relates to SPF roofing.
