Anti-UV PERT pipe is specifically designed to address the degradation that occurs when polymer pipes are exposed to sunlight. Standard PERT can become brittle and weak with prolonged UV exposure. This variant is manufactured with UV inhibitors—often a carbon black outer layer—that protect the pipe's structural integrity. This allows the pipe to be stored outdoors or installed in applications with temporary sun exposure (like pre-slab construction) without compromising its long-term performance, flexibility, and strength.
