Thermal Break Aluminum Sliding Doors Smooth Silent 100/150 Series SD-44

The Thermal Break Sliding Doors 100/150 Series Aluminum Smooth Silent SD-44 is engineered for exterior and interior use in residential, multi‑family, hospitality and commercial projects — ideal for patios, balconies, storefronts and office facades where large glazed openings, thermal efficiency and durability are required.

Use it to create expansive indoor‑outdoor transitions, provide operable access while meeting stringent energy and acoustic requirements, or replace fixed glazing in passive‑design homes, hotels and urban developments. The SD‑44’s smooth, silent rollers and corrosion‑resistant aluminum profiles make it well suited for high‑traffic entrances, luxury residences and coastal installations, and it integrates easily with curtain walls, screens and automated building systems.
