An Indow Mullion is an aluminum ‘H’ shaped profile that installs inside of a window frame to divide large window frames into smaller, more manageable units. Having two small inserts in a window versus one large insert are ideal in applications where the resident will want to easily remove the lower insert to open window for seasonal fresh air. The smaller inserts allow for easier storage when not used.
Mullions will need to be used for very large windows which exceed our 6 ft. x 8 ft. or 5 ft. x 10 ft. panel sheet maximums.
Dividing the window into more than one insert does not have a major impact on the overall cost the project.
