ProVia Windows in Portland, OR
ProVia has vinyl and wood clad product lines. Aeries is their wood clad option and Ecolite, Aspect and Endure are their vinyl options.
When it comes to replacement windows, not all vinyl is created equal. ProVia's SunShield® vinyl compound is the foundation of three of their most popular window lines — and it's one of the key reasons these windows outperform standard vinyl windows in durability, color retention, and long-term value.
SunShield® is ProVia's proprietary vinyl compound used in their Endure™, Aspect™, and ecoLite™ window lines. It's engineered specifically for the demands of exterior window frames — designed to hold up against UV exposure, temperature swings, moisture, insects, and the wear of daily life.
Unlike standard vinyl, SunShield® is formulated to resist the common failure points that frustrate homeowners over time. ProVia backs it with a warranty against rotting, cracking, pitting, corroding, and peeling — problems that can plague lower-grade vinyl windows within a decade of installation.
Long-Lasting Color
One of the biggest concerns with vinyl windows is fading. SunShield® vinyl is engineered for superior color retention, so your windows look as good years down the road as the day they were installed. No repainting required — ever.
Zero Maintenance
SunShield® vinyl never needs to be painted, stained, or sealed. It's resistant to rot, insects, and microbial damage, and cleans up easily with mild soap and water. For busy homeowners, that's one less thing to worry about.
Structural Integrity
The compound is designed to maintain its shape and seal over time, even through the freeze-thaw cycles and temperature extremes that Oregon winters and summers can bring. Combined with ProVia's welded frame and sash construction, SunShield® windows stay tight and draft-free long after installation.
