At Optimum Window, we have spent over three decades perfecting the balance between sustainability, performance, and design.
Our commitment to producing eco-friendly steel windows is rooted in utilizing 100% recycled steel, reducing waste, and adopting energy-efficient production processes.
As the largest and most diversified steel window manufacturer in the U.S., we prioritize green building practices while maintaining structural excellence and durability.
Sustainable Materials & Manufacturing
Recycled Steel: A Responsible Choice
Steel is one of the most sustainable materials available, as it can be recycled indefinitely without loss of quality.
Our hot-rolled and cold-rolled steel window systems are crafted using high-quality recycled steel, which significantly reduces the carbon footprint of our products
Advanced Powder Coating Technology
We employ electrostatically applied powder coatings, which offer a zero-VOC (Volatile Organic Compound) finish.
Unlike traditional liquid coatings that contain harmful solvents, our powder coating process ensures:
- Minimal environmental impact
- Long-lasting durability
- Corrosion and weather resistance
Thermally Broken Steel for Energy Efficiency
Our RTS430 Thermally Broken Steel Windows and 6500SB Series incorporate thermal breaks, which significantly reduce heat transfer.
This results in lower energy consumption and enhanced indoor comfort, meeting and exceeding NFRC energy efficiency ratings.
Eco-Friendly Manufacturing Practices
Waste Reduction & Recycling Programs
From design to production, every step in our manufacturing process is optimized to minimize material waste.
Any scrap steel generated is recycled back into production, ensuring a closed-loop manufacturing system.
Energy-Efficient Fabrication
Our facility in Ellenville, NY, is equipped with state-of-the-art computerized machinery for cutting, welding, and assembly.
This automation reduces energy consumption while ensuring precision and minimal material waste.
Water-Based Cleaning & Finishing
Instead of using harsh chemical treatments, our finishing process includes water-based cleaning solutions to remove contaminants without polluting water sources.
Eco-Conscious Window Designs
Fire-Rated & Sustainable Safety Solutions
Our fire-rated window systems provide safety while adhering to eco-conscious principles.
The FR6000 Series features fire-rated glazing that offers superior insulation, reducing heating and cooling costs.
Glazing for Thermal & Acoustic Insulation
We offer double- and triple-glazed options with Low-E (low emissivity) coatings, which enhance thermal performance and reduce energy consumption.
These features are integral to meeting modern energy codes while contributing to green building certifications.
Customizable, Long-Lasting Windows
Our steel windows are not just energy-efficient, but they are also built to last.
Unlike materials like vinyl or wood, steel frames do not warp, rot, or degrade, ensuring a longer life cycle with minimal replacements.
Commitment to Green Building Standards
At Optimum Window, we align our manufacturing processes with leading sustainability standards, including:
- LEED (Leadership in Energy and Environmental Design) compliance
- NFRC-certified energy efficiency
- Use of sustainable coatings and materials
Our green manufacturing initiatives, combined with timeless design and advanced technology, make our steel windows the optimal choice for architects, builders, and homeowners looking for sustainable, high-performance solutions.
Looking Forward
We continue to innovate with eco-friendly practices, ensuring that our steel window systems contribute to greener buildings, reduced energy consumption, and long-term sustainability.
Whether for residential, commercial, or landmark applications, Optimum Window remains dedicated to combining beauty, durability, and environmental responsibility.
