505 and 275 Discontinuation

Posted Apr 19, 2017

Due to changing market conditions and a drive to simplify our product offering, MI Windows and Doors will discontinue the manufacturing of all products in our aluminum 505 and 275 Series assembled in Flower Mound, TX. The last day to place orders for the 505 and 275 product families will be July 1, 2017. The final day of production will be July 31, 2017.


MI will no longer quote these products in the quoting group. All existing quotes/jobs should be discussed with your MI sales representative.


In place of the 505 and 275 Series, customers are encouraged to choose from our aluminum 185 or vinyl 3500.


The 185 aluminum single-hung window is ideal for storm-prone regions. This impact-rated window features a warm-edge spacer system and dual-pane insulated glass to help maximize energy efficiency and maintain interior temperatures year-round. The 185 also boasts a sweep-lock system that helps maintain home security.


Offering builder-friendly attributes like drywall pass though and snap-in sill, the 3500 vinyl single-hung window is an excellent choice for any new home construction project. The 3500 features a welded, multi-chambered frame and sash for superior strength and energy efficiency and heavy-duty weather stripping for protection against wind, rain, dust and noise.


All marketing collateral related to the 505 and 275 should be removed from showrooms immediately. If you would like additional information on the 185 or 3500, please contact your MI sales representative.
