Double-hung windows are part of the architectural heritage of North America.

MQ Windows has created with the Mistral T-200 the most accurate and performant reproduction of the double-hung windows of yesterday.  Tested as per the ASTM 1886/1996 standard, the T-200 was designed and engineered to fit both historic renovations as well as new constructions.

The Mistral Series-200, more robust, was engineered to meet the severe standards of the Miami-Dade County hurricane-resistance norms.
