Not all vinyl is created equal

The SunShield® difference.

SunShield® is ProVia’s proprietary vinyl compound used in the Endure™, Aspect™, and ecoLite™ window lines. It is engineered for exterior window frames and designed to withstand UV exposure, temperature swings, moisture, insects, and daily wear.

ProVia backs SunShield® vinyl against rotting, cracking, pitting, corroding, and peeling—supporting color retention, durability, and long-term value.
