Styline vs Titoni Windows: Comparing LA's Minimal Frame Manufacturers
Titoni is a newer entrant to the minimal frame market, also based in the Los Angeles area. With similar profile widths, how do these two California manufacturers actually differ? Here's what architects need to know.

Two California Manufacturers, Different Histories
Both Styline and Titoni manufacture minimal frame sliding doors in the greater Los Angeles area. On paper, their flagship systems share a key specification: 3/4" vertical interlocks. But the similarities largely end there.
Styline has been manufacturing minimal frame systems since 2012 — making it the first American manufacturer in this category, with over a decade of engineering refinement, hundreds of completed luxury projects, and a proven track record in the most demanding residential applications.
Titoni is a newer entrant to the market, positioning itself with the tagline "European aesthetic without tariffs." They also offer steel and bronze systems alongside aluminum, operating from facilities in Los Angeles with showrooms in El Segundo.
System Comparison
| Specification | Styline THINLINE 2500 | Titoni ICON |
|---|---|---|
| Vertical Interlock | 3/4" | 3/4" |
| Frame Concealment | Fully concealed | Snap-in covers |
| Maximum Panel Height | 20'+ | Not published |
| Glass Options | Up to 1-5/16" | 38mm (1-1/2") and 54mm (2-1/8") |
| Sill Options | 1" Low, 2" Flush, 3-1/4" Hidden + Absolute | Commercial flush (ADA) |
| Bottom Rail | Minimal stile | Standard |
| Hardware | In-house CNC billet aluminum | Stainless steel bearings |
| Track Record | Since 2012, hundreds of projects | Newer entrant |
Frame Concealment: A Critical Difference
While both systems achieve 3/4" at the interlock, the perimeter frame treatment differs significantly. Styline's frames are fully concealed — hidden entirely within the wall, floor, and ceiling structure so that no frame element is visible from either interior or exterior.
Titoni uses snap-in frame covers that conceal fasteners — a nice detail, but fundamentally different from true frame concealment where the entire frame disappears into the building envelope.
Hardware Philosophy
Styline designs and manufactures all hardware in-house, machining sleek handles and locks from pure billet aluminum in their own CNC fabrication department. This vertical integration ensures every component matches the minimal aesthetic and meets exact tolerances.
This in-house capability also means Styline can customize hardware profiles for specific project requirements — a flexibility that outsourced hardware supply chains cannot match.
Sill Versatility
Styline offers four distinct sill configurations — including the upcoming 1" Low profile sill, 2" Flush, and 3-1/4" Hidden + Absolute options. This range allows architects to specify the exact threshold treatment for each project condition, from ADA-accessible flush transitions to fully concealed installations.
Titoni's ICON PLUS system focuses on a commercial flush sill designed for ADA compliance — well-suited for commercial projects but offering less flexibility for the varied conditions encountered in luxury residential work.
Experience Matters
In minimal frame engineering, experience translates directly to reliability. Styline's nearly two decades of production have refined every aspect of the system — from structural calculations to weatherproofing details to installation methodology. Hundreds of completed projects across Southern California's most demanding luxury residences provide a proven track record that newer manufacturers cannot yet match.
The Bottom Line
Both Styline and Titoni offer quality minimal frame systems manufactured in California. For architects who prioritize proven performance, fully concealed frames, maximum panel heights, extensive sill options, and in-house billet aluminum hardware — Styline's nearly two decades of specialization in this exact category make it the established choice.
