Window IGU thickness debate
I have been in the window industry for about 16 years and i have heard many different takes on the difference between a 3/4″ IGU and a 7/8″ IGU. Are there any significant differences between the two related to energy efficiency such as the rate of convection between the panes? I would think a larger air space would allow for a more efficient unit but i would like some more input professionally. I also know that the type of spacer used makes a difference as well but for comparing apples to apples, lets say that we are comparing two units with the same specs, just with different thicknesses.
Thanks for any advice and help.
