  • Low maintenance requirements as long as the moving parts are functional, the only maintenance requirement is wiping, unlike wooden doors, which need polishing and sealing chipped areas.
  • Security – the flexibility in design accords solid security properties in uPVC sliding doors. Typical technology include internally beaded double-glaze designs, multi-point lock systems, and toughened laminated glass.
