Optional Mid Seal

The two moving panes typically overlap between 80 to 120mm.

To reduce air and water infiltration fit the mid seal. All windows are supplied with this removable seal as standard.

ClearVENT™ sashes without mid seal are cleaner to look through but be aware they don’t comply with the water or air infiltration requirements of Australian Standard AS2047.
If you plan to remove the mid seal we recommend having the maximum pane overlap.
The midseal is supplied in UV stabilised black rigid PVC.
