The truth about vinyl siding is that it's an environmentally sustainable product.
Life-cycle analysis tools, such as Building for Environmental and Economic Sustainability (BEES®)
software, demonstrate vinyl siding's high level of environmental performance. BEES is established per ISO 14040 and ASTM standards and is recognized by green building professionals as a useful tool for selecting environmentally preferable products.
Silica-based fiber cement, like James Hardie siding products, require special tools for installation along with a dust mask or respirator and may potentially cause adverse health effects such as silicosis (an incurable IlLl1g disease) for installers who do not use respirators?
-
Vinyl siding does not use any materials that can cause adverse health effects to installers or others.
-
Fiber cement requires periodic painting and caulking. Vinyl siding only requires occasional cleaning with mild soap and water, reducing the overall environmental impact of vinyl siding.
-
Vinyl siding requires less water and energy to manufacture per square than fiber cement.
-
Vinyl siding is lighter per square than fiber cement.
Most of the raw materials used to manufacture vinyl siding are typically shipped by rail or pipeline, which is more energy-efficient than an equivalent volume of raw materials for fiber cement that are typically shipped by truck.
Scrap from vinyl siding can be fed back into the manufachlring process, while fiber cement scrap is typically sent to landfills.
While BEES software does not specifically address fiber cement products, the production of cement is responsible for 7 to 8 percent of all human-generated carbon elioxide emissions, contributing to global warming potential.
Production of cement-based products, including fiber cement, is generally responsible for creating more elioxin than the production of vinyl siding
Bottom Line on Vinyl Siding
Fiber cement can contribute to earning relatively few points in the draft National Green Buileling Standard:" On the other hand, vinyl siding has the potential to
earn more points than other exterior cladeling, including fiber cement, because vinyl sieling requires no additional finish resources, may contain recycled content, and based on life-cycle assessment with BEES sofu'lare, qualifies as a more environmentally preferable product.
