More and more, homeowners are seeking out energy-saving building materials for their renovations and new homes, products that not only secure and improve structures but also provide long-term cost-cutting on energy bills while promoting environmental and economic sustainability in the greater community.
On a building or on a home, the roof has a major impact with the absorption of heat from sunlight (Solar Radiation). The heat is either reflected into the atmosphere or absorbed through conduction into the building. Any solar radiation that is absorbed will heat the roof’s surface. The more the solar radiation is absorbed, the greater the need to find alternative means to dissipate the heat. That’s where emittance comes into play. Emissivity is measures of the roof’s ability to shed absorbed heat.
Metal roofs typically have a minimum of 25% recycled content. This level of recycled content allows metal roofing to be routinely included on listing for “green” and recycled content products. It is also 100% recyclable when ultimately removed as part of building renovation or demolition. Other roofing materials are routinely removed and disposed of by the ton in a landfill, but metal roofing can be recycled by its entirety. Metals are exceptional building materials that can credibly claim both recycled content and recyclability by recognized definitions.
