Mobile Mullion

SERIES 4000 & H4000

Looking for a practical window?

A casement window equipped with a movable mullion is the best option to meet your needs and your building’s emergency exit requirements.

This new functionality allows the semi-operating sash to be opened from the inside without a key, without tools and without special knowledge. Built primarily for basement bedrooms, this window allows for rapid evacuation in the event of an emergency.
