The Leadership in Energy and Environmental Design (LEED) Green Building Rating System™ is the nationally accepted benchmark for the design, construction, and operation of high performance green buildings.
LEED for Homes is a voluntary rating system that promotes the design and construction of high performance "green" homes. A green home uses less energy, water, and natural resources; creates less waste; and is healthier and more comfortable for the occupants.
Sustainability provides opportunities to create value and improve quality of life for the company, people and the community. Strong environmental and social performance contribute to sustained profitable growth.
A life cycle analysis is a study of the environmental impact of a given product or service throughout its lifespan.
Low embodied energy, high recycled content, no additional finishing, durability, low maintenance, cost effectiveness, and the ability to recyclable at end of life are some of the key green attributes. Some of CertainTeed polymer siding, vinyl siding and trim products meet these (or some of these) green attributes.
CedarBoards™ Double 6 contains 60% recycle content. This information is audited quarterly by an independent third party. This high recycle content helps in qualifying for LEED H, LEED NC, and NAHB green building credits for environmentally proffered products. CedarBoards D6" is one of only a few cladding options that provides this benefit (not fiber cement and no other vinyl siding product).
The International Energy Conservation Code (IECC) provides the minimum energy efficiency provisions for residential & commercial buildings. It contains building envelope requirements for thermal performance (R-value) by climate zones. See below for some examples.
By providing additional R-value, CedarBoards can help you meet the requirement when residing your house or building a new one.

Phthalate are used in a large variety of products ranging from shower curtains to perfumes or agricultural additives, making people commonly exposed to phthalates. They are linked to change in hormone levels and birth defects and are being phased out of many products in the US and in Europe. More details can be found at http://en.wikipedia.org/wiki/Phthalate
Heavy metals as defined in medical usage include all toxic metals; heavy metal poisoning can include excessive amounts of iron, manganese, aluminum or beryllium. Toxic metals sometimes imitate the action of an essential element in the body, interfering with the metabolic process to cause illness. More details can be found at http://en.wikipedia.org/wiki/Toxic_metal
CertainTeed vinyl does not contain phthalates or heavy metals. Many in the green building community are focused on the elimination of these components. . While many other manufacturers do use them, CertainTeed has not used them.
According to Hanley Wood, insulated siding is one of the top upscale projects in terms of recouped cost. Even more important insulated vinyl siding projects are one of the few projects that show signs of increasing in value (compared to 2007)… this is driven by energy efficiency/cost savings and green trends.
