3. Natural stresses
The dehydrated gas space(s) thus formed are sensitive to variations in atmospheric pressure and temperature, and possibly to their own weight and snow in the case of inclined glazing.
3.1 Atmospheric pressures
Atmospheric pressure decreases with altitude. If the altitude of the installation site is higher than the manufacturing altitude, the gas blades in insulating glass units will expand (figure 4 ).
