Adjusting windows for High Altitudes (5000 ft Denver)

Hello everyone. We have a zero energy passive house that we need to transport to Denver. Obviously, the windows are not meant for 5000 feet altitude. The manufacturer said that it shouldn't go above 3000-4000 ft.
It doesn't have capillary Tubes installed. Please, if you have any idea of the possible solutions, let us know.
We were actually thinking to drill through he side frame and releasing the gas. Do you think this might work?
thank you!!!

No, you cannot and should not do that.... unless you don't mind replacing all the glass in your windows in a short time when they start to fog up.

When purchasing windows for high altitudes you need to purchase windows that have capillary breather tubes. Capillary tubes can be purchased and installed, but this requires the removal of the IGU (the insulating glass unit) so that the breather tube can be inserted and sealed correctly. The tube is then crimped to seal it once the windows have reached their final altitude.

Many window companies will install the breather tubes if they know in advance that the windows will be shipped to high altitudes.
