Insulated Garage Door Windows Available for Homes at High Altitudes

Aug 10, 2010

High-altitude insulated glass is now available on several Clopay residential and commercial garage doors.

What’s the need?

Standard insulated glass can break due to pressure changes at altitudes above 5,000 feet. High-altitude glass has a capillary tube installed through the spacer to equalize any pressure differential between the inside and outside of the glass unit.

High-altitude insulated glass is an option on the following residential garage doors that currently offer insulated windows:

It is also available on square or rectangular shaped plain windows.

  • Grilles and inserts are available to use with this type of glass
  • Not available on decorative windows such as Brilliance or Leaded Series.
  • Not available on arched windows

And the windows qualify for the Energy Tax Credit.

NOTE: High-altitude glass should not be used for installation at an elevation less than 3,000 feet above sea level. Doing so could increase moisture infiltration in the windows, producing a fogged appearance.
