Window & IGU FAQs
Q: What is an IGU?
A: An Insulated Glass Unit (IGU) is a double or triple-pane window sealed with an insulating gas (like Argon) to keep out the Colorado cold and heat.
Q: What keeps moisture out of the panes?
A: Inside the metal perimeter spacer bar is a moisture-absorbing material called desiccant. It drinks up any internal humidity. Once the window's outer seal breaks and lets outside air leak in, the desiccant gets 100% saturated and can no longer hold the moisture.
Q: How do I spot a failed seal?
Fogging: Trapped moisture or condensation between the glass panes that you can't wipe away.
Hazing: A white, cloudy film left behind inside the glass as trapped water constantly evaporates.
Distortion: The glass looks warped or bowed from the outside because the insulating gas has escaped.
Q: What causes the seal to fail?
Thermal Pumping: Intense high-altitude sun during the day and freezing temperatures at night cause the glass to expand and contract aggressively, tearing the seal over time.
Water Pooling: Clogged frame weep holes trap standing water along the bottom edge of the glass, rotting out the seal.
Q: Can you fix the seal, or do I need new glass?
A: Failed units cannot be resealed on-site. We leave your existing window frame entirely intact, but we extract the old glass and replace it with a brand-new, factory-sealed IGU to restore your view and energy efficiency.
