Architectural Style & Vertical Balance Engineering

Designed to maximize natural ventilation while offering superior structural weatherproofing, our thermally broken single hung windows provide slim frame profiles and finger-touch operation, even on heavy architectural glass sashes.
Decorative Architectural Grid Patterns (Divided Lites)

Enhance your project's architectural character with custom grid configurations. We offer internal Grilles Between Glass (GBG) for low maintenance, and Simulated Divided Lites (SDL) with external dimensional bars for authentic Craftsman or modern transitional aesthetics.
Custom CAD Shop Drawings & Technical Support

Accurate rough openings and perimeter sealing details are essential for vertical sliding systems. Our engineering team provides custom 1:1 CAD shop drawings, egress compliance verifications, and wind-load calculations for architects and general contractors prior to production.
Precision Manufacturing & Assembly Operations

Every window and door system is manufactured in our standardized workshop using automated processing equipment and rigorous assembly protocols. From corner crimping and structural sealing to final assembly and inspection, we ensure strict quality control for all export orders.
