Why Choose Simonton Windows?
Simonton has been a leader in vinyl window and door manufacturing for over 75 years. Over the decades, each product has been engineered for durability, energy efficiency, and visual appeal — making them a perfect fit for Orange County homes, especially where both performance and aesthetics matter.
Key Benefits:
- Energy Star® Certified – As a result, you can reduce energy costs throughout the year.
- Customizable Styles – Moreover, you can choose from a variety of colors, finishes, and hardware.
- Low Maintenance Vinyl – Best of all, there’s no need for painting or staining.
- Noise Reduction – In addition, these windows help keep outdoor sounds where they belong.
- Lifetime Warranty – Consequently, you’ll enjoy added peace of mind as a homeowner.
One of Simonton’s most popular offerings is the DaylightMax™ series, which is specially designed with less vinyl and more glass compared to traditional window frames. As a result, more natural light can enter your home, creating a brighter, more open living space — a major plus for both comfort and resale value.
Additionally, Simonton windows feature an elegant matte finish on vinyl frames. Unlike glossy finishes that can appear plastic-like or cheap, the matte texture provides a high-end, architectural look that enhances your home’s style and appears far more expensive than it is.
