Frequently Asked Questions
Can your window systems be approved for landmarked buildings under NYC LPC guidelines?
Yes, absolutely. We specialize in replicating landmark configurations. Our custom steel profiles (Secco®, Forster®) and proprietary OpenSky® systems are specifically engineered to match the historic sightlines, sash proportions, and brick-mould details required to secure a Certificate of No Effect (CNE) or Certificate of Appropriateness (COA) from the Landmarks Preservation Commission.
How do your slim-profile systems combine historic landmark replication with modern energy codes?
We integrate breakthrough technology like Next-Gen Vacuum Insulated Glass (VIG) into ultra-slim historic-grade frames. This allows architects to maintain exact single-pane visual proportions and razor-thin muntin profiles while delivering the state-of-the-art thermal insulation, U-factors, and soundproofing of heavy triple-pane windows.
Are your European glazing systems fully NFRC rated and code-compliant in the US?
Yes. All our factory-direct European window and door systems are fully adapted for the US market. We provide comprehensive thermal simulations, structural calculations, and NFRC-compliant performance metrics to ensure complete compliance with strict NYC Energy Conservation Codes, local structural wind-load demands, and Local Law 97 regulations.
Do you provide fully detailed architectural shop drawings for the submittal process?
Absolutely. Once your project blueprint or CAD files are submitted, our in-house engineering team generates highly detailed, line-by-line cross-section shop drawings and elevation plans. We work hand-in-hand with your design firm to provide the precise visual and technical documentation needed for smooth staff-level approvals.
What is your project execution model, and do you handle installation in-house?
We operate on a single-source responsibility model. OpenSky Window is a fully licensed, bonded, and insured contractor in NY and CT. Our own certified field crews handle the high-precision installation, perimeter sealing, and final hardware tuning in-house, backing the entire project with a comprehensive 10-Year Structural Warranty.
Do you offer financing?
Yes. Qualified customers can receive financing with 0% APR for up to 12 months, project financing up to $250,000 and flexible terms from 2 to 12 years.
