Sliding


Sliding doors don’t encroach on living or outdoor areas, giving clean lines and high performance in windy spaces.

  • Large glass panels and narrow frames give unobstructed views when closed
  • Doors can be sized to any height and width
  • Flush sills increase indoor-outdoor flow
  • Option to slide away into a wall cavity or over the exterior to open up living spaces
  • The sliding panel/s can be internal or external, depending on the range.

Bi-fold


Bi-fold windows fold open to give you clear views and maximum airflow.

  • Moving panels glide easily
  • Work well in large spans
  • Free-swinging panels offer easy access
  • A layback option is available on some bi-fold configurations that allows two panels to fold against the adjoining wall.
