DESIGNED & MANUFACTURED IN SIMI VALLEY, CALIFORNIA
Why Made in
California Matters
Styline is the only manufacturer producing ultra-minimal frame sliding doors with 3/4-inch (19mm) sightlines entirely in the United States. Our Simi Valley, California facility delivers the same precision as Swiss and German imports — with domestic lead times, native U.S. code compliance, and factory-direct engineering support.
For nearly 20 years, Styline has manufactured minimal frame door and window systems for luxury residential and commercial architecture across North America. Every system is designed, engineered, fabricated, and assembled under one roof in California.

Local Engineering Support
Same-timezone technical consultation. Factory visits available. Your architect speaks directly with the engineers who designed the system.
NFRC, AAMA & NAFS Tested
Tested locally to NFRC, AAMA/WDMA/CSA 101/I.S.2/A440, and NAFS standards. Full U.S. code compliance from day one — no retrofitting required.
California-Made vs. European Import

One Facility. Complete Control.
Styline's manufacturing facility at 420 E. Easy Street, Simi Valley, California houses every stage of production under one roof: engineering design, aluminum extrusion finishing, thermal break insertion, glass cutting and insulating unit assembly, hardware integration, quality control, and final assembly.
This vertical integration means no outsourced components, no third-party assembly, and no quality variables between design intent and delivered product. When your architect specifies a custom finish or non-standard dimension, the same team that designed the system fabricates it.
For architects and builders accustomed to European minimal frame systems, Styline offers a familiar level of engineering precision with the practical advantages of domestic manufacturing: faster delivery, easier communication, simpler warranty service, and immediate access to replacement components.
Frequently Asked Questions
What is the thinnest sightline sliding door made in the USA?
+
Styline's THINLINE 2500 Series features 3/4-inch (19mm) vertical profiles — the thinnest minimal frame sliding door manufactured in the United States. Designed, engineered, and assembled in Simi Valley, California, it matches or exceeds the sightline dimensions of European imports like Vitrocsa (18mm) and Sky-Frame (~20mm) while offering 8-12 week domestic lead times, local service, and full U.S. code compliance.
Why choose a California-made minimal frame door over a European import?
+
California-manufactured minimal frame doors offer 8-12 week lead times (8-10 standard, 10-12 complex scope) versus 16-24 weeks for European imports, eliminate international shipping costs and customs delays, include factory-direct engineering support in your timezone, are pre-certified for California Title 24 energy compliance, and are tested to AAMA/WDMA/CSA 101/I.S.2/A440 standards. Styline's Simi Valley facility provides all of these advantages while matching the ultra-slim profiles of Swiss and German competitors.
Are Styline doors compliant with California Title 24?
+
Yes. All Styline systems are designed from the ground up for California Title 24 compliance. Because Styline manufactures in California, their engineering team works directly with the state's energy code requirements during the design phase — not as an afterthought. Every system is NFRC listed and tested per NAFS (AAMA/WDMA/CSA 101/I.S.2/A440) standards.
How does domestic manufacturing affect lead times for minimal frame doors?
+
Styline's California manufacturing facility delivers typical lead times of 8-12 weeks from order to delivery — 8-10 weeks for standard scope projects and 10-12 weeks for more complex configurations. European manufacturers like Vitrocsa (Switzerland) and Sky-Frame (Switzerland) typically require 16-24 weeks including ocean freight, customs clearance, and potential delays. For time-sensitive luxury residential projects, this difference can mean the difference between meeting and missing a construction schedule.
What testing certifications do Styline doors carry?
+
All Styline systems are NFRC listed (searchable in the NFRC Certified Products Directory), tested per NAFS (AAMA/WDMA/CSA 101/I.S.2/A440) standards, and California Title 24 compliant from day one. Because testing is performed locally in the U.S., results are directly applicable to American building codes without adaptation or re-certification.
