Ameristar Windows & Doors proudly offers The Onyx Collection, a flat-black vinyl windows line engineered from the inside out. This advanced profile delivers lasting beauty and reliable performance in intense heat, giving homeowners a modern look with the durability they expect from premium vinyl replacement windows.
Rated to 200 °F
The Onyx Collection offers exceptional heat resistance, performing at temperatures up to 200°F. This exceeds standard vinyl, typically rated around 162°F, and helps vinyl windows, especially black vinyl windows, maintain their shape and smooth operation while supporting energy-efficient windows performance in hot climates.
Engineered for Stability
The Onyx Collection is engineered to resist window warping. Intense heat, direct sun, and moisture can cause frames to expand or shrink, but this onyx profile maintains dimensional stability so sashes track true and seals stay tight. The result is smooth operation and reliable energy performance for vinyl windows and black vinyl windows, making it a strong choice for window replacement projects that prioritize energy-efficient windows in hot or high-sun environments.
Long-Lasting Deep Color
The Onyx Collection preserves its deep onyx color under UV exposure, temperature shifts, and changing conditions. Its distinct onyx shade pairs well with many aluminum windows and doors, giving your home or building a modern, upscale look that rises above traditional white vinyl. The Onyx Collection profile meets ASTM International and AAMA standards.. The series also meets the latest NFRC Energy Star 7.0 requirements when configured with qualifying glass, recognized as the most rigorous energy efficiency standard in the U.S., supporting strong thermal performance and long-term comfort.
