Awning windows offer unique benefits for homeowners, especially in regions with frequent rain or a need for ventilation without sacrificing security. Unlike standard casement or double-hung styles, awning windows hinge at the top and crank open outward from the bottom, creating a canopy effect that directs rain away while allowing fresh air in. They're perfect for kitchens, bathrooms, or any space where moisture control matters.
The Simonton Prism Platinum stands out in this category as a double-pane vinyl model priced at around $1,031. In our hands-on evaluations at Review Atlas, it earned high marks for everyday usability and long-term reliability. With a Review Atlas score of 8.2/10, it balances affordability, energy efficiency, and robust construction. Whether you're renovating or building new, this window delivers value without compromising on quality.

This table highlights the Prism Platinum's edge in comfort and sealing at a mid-range price. It outperforms averages in critical areas like air and water resistance, making it ideal for humid climates.
Our testing simulates real-world conditions: high winds, heavy rain, and daily use. The Simonton Prism Platinum shone here.
At just 0.1 cfm/ft², this window minimizes drafts, keeping your home warmer in winter and cooler in summer. That's 60% better than the industry average, translating to potential energy savings of 10-15% on HVAC bills annually.
Zero penetration during simulated storms—impressive for an awning design. The triple weatherstripping and sloped sill channel water away effectively.
Certified to withstand 50 mph gusts, it holds up in moderate storms. Forces required to open, close, and latch are very low (under 5 lbs), earning a 'Very Good' operation score.
Excellent comfort ratings come from the argon-filled low-e glass, which blocks UV rays and reduces noise by up to 30% compared to single-pane options.
Crafted with fusion-welded vinyl frames and sashes, the Prism Platinum resists warping, cracking, or fading over decades. The low-e glazing with argon gas fill boosts insulation (U-factor around 0.28), while composite hardware ensures smooth, rust-free operation. Half screens are standard, with sturdy insect frames for easy removal and cleaning.
Finishes are low-maintenance—no painting required—and the overall build weighs in at a lightweight yet sturdy profile, perfect for retrofits.
These features make it user-friendly for families, with operation as simple as turning a handle.
