Integrity Offers Expanded Factory Mulling Options For Ultrex Product Lines


Fargo, N.D. – Integrity Windows and Doors now offers expanded Factory Mulling options for Wood-Ultrex® and All Ultrex® configurations.

Now you can get your Integrity windows and doors factory mulled and ready to install up to 7 wide x 1 high or 5 wide x 5 high. The jobsite just got a whole lot easier.

Expanded factory mulling options are available on a variety of Casement, Awning, Double Hung and Glider products in the Wood-Ultrex series. In the All Ultrex series, expanded factory mulling options include Casement, Single Hung, Double Hung, Awning and Glider products.

“Expanded factory mulling options are another way Integrity is meeting the needs of our customers,” said Garrett Wilson, product marketing manager for Integrity Windows and Doors. “These new mulling options allow customers a new range of choices in assembly configurations for their windows and doors.”

The expansion of the product lines does not change the existing All Ultrex and Wood-Ultrex product configurations and rough opening limitations. Integrity encourages you to confirm your project and local building code requirements to determine specific accessibility, egress and other compliance requirements.
