About MonRay

Mon-Ray storm windows, or secondary glazing windows, are specifically designed with an attractive appearance and exceptional air, water and acoustical performance to improve the quality of your indoor environment. They are easy to operate, clean, and can be installed either to the exterior or interior of existing prime windows.

The Mon-Ray storm windows are used on projects that focus on Energy ConservationEnvironmental ProtectionHistorical Restoration, and Sound Abatement. In addition to being installed on tens of thousands of homes throughout the United States, Mon-Ray storm windows have been installed in thousands of schools, college and university buildings, hospitals, and other public and private commercial buildings. Independent studies (see Harvard Article) have selected Mon-Ray storm windows as the “better value” for conserving energy, reducing maintenance, and abating outside noise.

Some of the unique features of Mon-Ray storm windows include:

  • Constructed of strong T6 aluminum, which is far superior to the T5 aluminum or vinyl used by other manufacturers.
  • Weather-tight, ratchet action jamb liners with automatic ventilation settings every two inches.
  • Stainless steel, spring-loaded pin-locks and full-length extruded lift rail provide sure grip and handling.
  • Covered by the Mon-Ray Ten (10) Year Limited Product Warranty that is non-prorated and fully transferable.

Mon-Ray storm windows are available in two different frame styles: the Mon-Ray 500 Series and the Mon-Ray 600 Series, as well as in different types of miscellaneous glass panels and screens.
