Flush 70 Window with Scribbed Mullion

Improve your window in an instant with a Zero Sightline Mullion

Designed to the highest specifications using specialist technology, sightlines are improved by an impressive 34mm. The secret is the removal of the traditional mullion and replacing it with an ‘invisible’ mullion with a cover strip inside. The result is a neat line on the outside with no visible mullion and a thin cover strip inside.

Available for CWG’s Flush 70 range exclusively, not only is this feature aesthetically pleasing, its uses are endless.

  • 34mm improved sightline
  • Can be used as floating mullion
  • Can be used as a scribed mullion
  • Available as a zero sightline transom


Flush 70 available with zero sightline transom for improved sightlines

By the same token this ‘INVISIBLE MULLION’ can be used as a ‘zero sightline transom’.
It cannot be used in windows incorporating a cruciform design.
