Glass sliding door units, available in both top-hung and bottom-roller configurations, provide a refined and space-efficient way to access outdoor areas. Top-hung systems suspend the door panel from above, allowing for effortless gliding with minimal floor track interruption—ideal for clean finishes and flush internal transitions. Bottom-roller systemscarry the weight at floor level, offering excellent load capacity for larger or heavier doors, making them suitable for architectural glass designs. Both systems deliver practical functionality with a minimalist aesthetic, offering durability, weather sealing and smooth movement when paired with quality hardware and joinery craftsmanship.
