A Responsible Choice, From Start to Finish
Windows are responsible for 25–30% of heating and cooling energy use in most homes, so upgrading to high-performance options can make a big dent in your energy bills and your carbon footprint.
At Keystone Window, we believe great windows should make life better, not just for your home, but for the environment, too. That’s why we’ve partnered with Vytex Windows, a manufacturer committed to sustainability at every step of the process.
Vytex windows are designed for long-term energy savings, minimal waste, and a reduced environmental footprint. Together, we’re making choices that are better for your home and better for the planet.
How Our Manufacturing Process Reduces Waste
Vytex uses first-generation PVC (Polyvinyl Chloride), a stronger, longer-lasting material that resists degradation and reduces the need for replacement. Their state-of-the-art robotic welders and automation systems help minimize production waste by optimizing every cut.
Even when there’s excess, nothing goes to waste:
- Over 90% of leftover vinyl and glass is recycled and repurposed across other industries.
- Glass scraps and broken insulated glass units (IGUs) are collected and sent to recyclers (except laminated glass).
- Metal and aluminum are also recycled regularly.
- Even cleaning solutions used in the factory are biodegradable.
When surplus or uninstalled windows remain, Vytex donates them to local charities, keeping usable materials out of landfills and supporting community development.
Sustainable Finishes and Smarter Energy Use
Vytex windows aren’t just built to last, they’re built to perform. They qualify for Energy Star standards, meaning they’re independently certified for real-world energy efficiency under the National Fenestration Rating Council (NFRC) program.
They also offer VyCoat™ finish options, which use low-VOC, environmentally friendly paint. These finishes provide long-lasting color and durability while minimizing harmful emissions during production.
Fewer Replacements = Less Landfill Waste
Energy-efficient windows don’t just help reduce your monthly bills; they reduce your overall carbon footprint, too. Our Energy Star–rated vinyl windows are designed to lower the demand on your HVAC system, which means your home uses less energy for heating and cooling year-round.
Better still, Vytex’s windows are built to last. That means you won’t be replacing them again anytime soon, avoiding the cycle of waste that comes with poorly made products. A longer lifespan means fewer materials end up in landfills.
Certified Quality & Industry Standards
All of our windows meet or exceed NFRC energy performance ratings and AAMA (American Architectural Manufacturers Association) standards. These rigorous certifications ensure airtight frames, excellent insulation, and superior overall efficiency.
