Select a category of building materials (carpet, vinyl flooring, pre-finished wood panels), and then select three different products within this category that have different levels of transparency.
One product that has very little information available regarding its chemical contents
One product that has first-hand claims from the manufacturer regarding the health of the product, but no third party certification
One product with a third-party certification
Compare and contrast the three discussing various advantages and disadvantages of each project. Pros and cons outside of health and environmental impact might also include budget and lead time. Please included specification sheets for each project as well as documentation of any certifications.
