Did You Know?
2 million tons of glass and window components are thrown into landfills every year.
2 million metric tons of greenhouse gases are produced making windows every year.
The average life expectancy of an insulated glass unit is only 12 years, yet the components will last much longer.
By 2008 foggy window repair companies had saved over 250,000 windows keeping approximately 3000 tons of glass out of landfills. Manufacturing and installing new windows and glass for these 250,000 windows would have produced 5000 metric tons of greenhouse gases
How we cure a Window
Our process re-engineers the window to reverse the accumulation of moisture. We drill small vents into the window, either directly through the glass or into the spacer bar of the window. Now as the window heats up and the air expands it starts to release the moisture out of the window. Imagine a partially full water bottle with it’s lid tight in the sun. The water will never dry out because the water has no where to go. However remove the lid, and put an attachment over the lid to make sure no rain, snow etc can get inside. It will dry out and stay dry. We are basically doing the same thing with a window. The key is (1) make sure the moisture has a place to go and (2) make sure water cannot get back into the window, either through the vent we drill or though the seal.
Another positive aspect of this process is that the vents or membranes act to pressure regulate the window. No longer will the heat put external pressure on the seals or will the extreme cold cause the window to be at a negative pressure and pull moisture into it.
The benefits of this process: No mess from tearing apart the window sash or frames to replace the window or thermal glass unit. Reduce green house gas emissions by reducing the manufacturing and transportation of glass and other window components, and waste glass to fill landfills. The cost is significantly less that replacing the glass or the window.
Why Windows Fail:
Thermal windows are manufactured to be a sealed unit. But it is difficult to maintain a perfect seal. Manufacturing, transportation and installation can destroy the seal. The atmospheric pressure changes exposure to weather and the radiation from the sun all act on that seal.
The majority of failed thermal glass units are found on the sunny side of the property because of the extreme heat exerted on the windows. In fact in testing I've done the temperature reached 160 degrees.
When it is very cold the pressure inside a window drops. The window can even suck water into it. This especially happens in high humidity areas like bathrooms. On one bathroom window I worked on the window had filled up 2 inches of water. When I drilled into the spacer bar the window continued to pull air into the window until the pressure had equalized to the outside air pressure.
Eventually because of this all windows will fail. The average lifetime of a window is 12 years.
