Made by TRC
- RTRC manufactures by extrusion. This is the most advanced method for EPDM production.
- RExtrusion delivers uniform thickness, no air pockets, no surface dimples, and zero risk of scorching. These are defects common in calendered membranes.
- RThe result: A smoother, more reliable membrane that installs more easily and lasts longer.
- QCalendered membranes, still used by many suppliers, are prone to pinholes, voids, and thickness inconsistencies.
