Proudly manufactured in the U.S., MasterShield Gutter Protection's aluminum contains more than 95% recycled content and the stainless steel is made up of at least 30% recycled material (a higher percentage would not meet surgical grade standards). Any metal trimmed from the product during installation is also 100% recyclable. The adhesive used in the product meets requirements that would allow it to be in contact with edible products. The company recently announced their new MicroVortex technology, which the company calls the “Impossible Cloth." Not only does MasterShield make their products from recycled materials, but their executives and individual dealers belong to eco-oriented professional organizations, and the company is committed to raising awareness of responsible gutter related initiatives such as water reclamation.
