The Firestone 2-Part Gutter Trim is a specific component used in Firestone's roofing systems for efficient water drainage. It's designed to work in conjunction with Firestone's EPDM rubber roofing membranes. This gutter trim typically consists of two parts: an outer trim and an inner insert. The outer metal trim provides structural support and a clean finish to the edge of the roof, while the EPDM rubber insert acts as a waterproof seal between the trim and the roofing membrane, ensuring proper water drainage and protection against leaks.
