When it comes to historic restoration in New York City, homeowners and architects face a common challenge: balancing preservation with performance. Landmark Windows are designed to honor architectural history while still delivering the energy efficiency and durability modern buildings demand. But how do they really compare? Let’s break it down by answering the most pressing questions.
Are Landmark Windows Still ENERGY STAR® Certified?
Yes, Landmark Windows can be manufactured to meet ENERGY STAR® standards, ensuring they deliver insulation and efficiency comparable to today’s leading window brands. By integrating double or even triple glazing, thermal breaks, and low-E coatings, Landmark Windows provide historic accuracy without sacrificing performance.
How Do Landmark Windows Compare to Newer High-Performance Brands?
Modern high-performance windows often emphasize cutting-edge technology, but Landmark Windows bridge the gap by pairing historic craftsmanship with contemporary engineering. Compared side by side, Landmark Windows:
Match competitors in U-value and SHGC ratings
Maintain architectural authenticity required by NYC Landmarks Preservation Commission
Offer custom detailing not found in mass-market high-performance lines
Do Landmark Windows Still Meet 2025 Energy Efficiency Standards?
With updates in building codes and energy standards, 2025 sets a new bar for performance. Landmark Windows can be tailored with advanced glazing, inert gas fills, and insulated frames to exceed minimum code requirements, making them fully compliant with upcoming regulations.
Are Landmark Windows Worth It Compared to Newer Competitors?
Absolutely. While off-the-shelf brands may seem cost-effective, they rarely align with the requirements of landmarked properties. Landmark Windows provide:
Long-term value through durability and energy savings
Compliance with preservation rules in New York City and beyond
Custom design flexibility that modern competitors can’t replicate
What’s the Current Warranty and Performance Rating of Landmark Windows?
Landmark Windows typically come with comprehensive warranties covering frames, glazing, and finishes. Performance ratings meet or exceed industry standards, offering peace of mind that your investment delivers both beauty and efficiency for decades.
The Bottom Line
Landmark Windows prove that historic preservation and high performance are not mutually exclusive. For architects, builders, and property owners working on landmarked buildings, they represent the best of both worlds: timeless aesthetics with cutting-edge energy performance.
If you’re considering a restoration project in New York City or beyond, Landmark Windows remain one of the strongest investments for long-term value, compliance, and efficiency.
