Description

Bi-fold doors and windows share the same profiles and operating system. Panels are bottom rolling with the weight carried on the sill.

The roller and guide are pivoting inserts within the door stiles thus optimising overall ease of operation. Door panels are 50mm deep and are bead glazed externally on all sides for glass thicknesses of 4-28mm.

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