54 DRAIN offers all of the versatility and flexibility of the 54 CLASSIC with an ingenious hidden sill design. Removable finish floor clips allows easy access for future maintenance. OTIIMA’s hidden sill design is notable for utilizing a single slot for each track. Some competitor’s designs require two slots per panel. The 54 Series is specifically designed for cold climates by utilizing 54mm (2-1/8") triple-pane insulated glass. The 54 Series can accommodate oversized “jumbo” double-pane glass. Multiple laminated glass options are available when noise reduction and/or impact performance is desired.
Available configurations include fixed windows, multi-panel and sliding windows/doors (including pockets and corner-opening configurations). Door automation can be integrated with all of our sliding doors.
