Description

Metro Series bifold doors and windows use the same system, which is bottom-rolling with an in-frame track.

A lay-back option is available for certain configurations — 2-panel, 2+2 and 2+1, where the open panels fold back against an adjoining wall for an unobstructed deck.

For best overall performance, pair with The AGP System® with Solux-E® or Solux Ultra® low-e glass.

Key Features
  • Maximum 2400mm high doors in very high wind zones — for larger sizes consider using the APL Architectural Series
  • Maximum glass panel thickness of 27mm
  • Corner bi-folds are available that do not require a corner post
  • The efficient bottom roller system allows optimum load capacity and increased panel width
  • Single panel access door can be used in conjunction with bi-fold doors
