38 CLASSIC is one of the most popular systems in the lineup of products. Both thermally versatile and structurally robust, it offers the flexibility for use in both warm and moderately cold climates. Designed to accept 38mm (1-1/2") insulated glass, the 38 series can also accommodate triple-pane glass, depending on the thermal demands of the project.


The 38 Series' use of stronger and thicker tempered glass, integrated with the structural components, allows for panel sizes to be much larger than our competitors. Ultrathin sight lines are achieved through three distinct methods: structural glazing, reinforced components and engineered interlocking mullions. OTIIMA's framework has been purposely designed for structural integrity while maintaining a minimal visible profile.


Available configurations include fixed windows, multi-panel, sliding windows/doors (including pockets and corner-opening configurations) and guillotine windows/doors (ascending/descending panels). Curved (radius) and sloped/leaning units are also available. Door automation can be integrated with all of our sliding doors.


38 CLASSIC Maximum Panel Size:

Domestic Standard Insulated Glass = 100" x 144"

Domestic Jumbo Insulated Glass = 126" x 268"

European Insulated Glass = 126" x 295"
