According to a just-released BCC Research study. In 2009, the second largest segment of US commercial roofing market (just behind metal roofing) is Sprayed-Polyurethane Foam (SPF) Roof Systems, expected to increase from a value of $420 million to nearly $1.1 billion in 2014, for a CAGR of about 21%! Sprayed polyurethane foam (SPF) roofing consists of an application of specifically designed foam covered with an elastomeric coating (typically acrylic, silicone, or polyurethane) or aggregate covering to protect the foam from ultraviolet rays. Specialized equipment mixes two liquid components (isocyanate and polyol) at the spray gun that applies the SPF to a prepared substrate. What makes SPF Roof System so unique is its Sustainability. Oake Ridge National Laboratories (ORNL) 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, and reduce waste generation throughout the life cycle from design, through construction and reroofing, to reuse and final disposal”. In other words, Sustainable Systems preserve natural resources (environment), reduce landfill waste (dry-up waste stream) and provide maximum life cycle cost efficiency. SPF Roof Systems are more than remarkable on each and every of these performance items.
Yes! I would like to be alerted on new publications.
