New Vinyl Siding EPDs Deliver Sustainability Transparency in User-Friendly Format

For building and design pros looking to maximize the sustainability of their homes, the Vinyl Siding Institute (VSI) has added another tool to help make greener product choices for the home exterior. VSI, of which Westlake Royal Building Products is a member, recently published three Environmental Product Declarations (EPDs) outlining the life cycle story of polymeric siding. The EPDs’ user-friendly package makes it easier to understand the sustainability specifications of vinyl siding.

The three EPDs—covering industry-averaged vinyl siding, insulated vinyl siding, and polypropylene siding—were developed in accordance with standards developed by the International Organization for Standardization (ISO). Each outlines the environmental impact of the product over the course of its life, including raw material extraction and transport, manufacturing, and waste generation. By offering data in a transparent and standardized way, EPDs allow product specifiers to make apples-to-apples comparisons between different products and material types. This helps provide transparency and authenticity in sustainability research.

However, these newest EPDs forgo the typical numbers-heavy report that can feel too complex and unapproachable. Instead, VSI says the marketing-style guides feature easy-to-read text and graphics, along with an organized chronology of features and benefits that make the data more accessible and understandable for both pros and their customers.

Each EPD includes:

• A summary of vinyl siding advantages

• Detailed measurements outlining the siding’s carbon footprint, from the efficient manufacturing process to end-of-life recyclability

• A look at vinyl siding’s recyclability

• An overview of vinyl siding’s 50+-year life span

• Material elements

• A list of green building programs offering credits for vinyl siding

• Accessible metrics outlining environmental data and life cycle

Though vinyl siding has sometimes been overlooked for green buildings in the past, data reveal that vinyl outperforms almost all other common cladding materials in total environmental impact. This includes in the areas of waste, toxic chemicals, overall environmental impact, recyclability, and longevity. (Read more about vinyl siding’s green attributes.)
