I am in the final process of deciding which type of replacement window to purchase. Some postings state that argon gas dissipates from double-paned windows within 5 to 7 years. Does it dissipate faster in wood clad aluminum vs vinyl or fiberglass replacement windows.
I live in the midwest with cold winters and would like an energy efficient window that will last for 20 years. Since I have an Arts and Crafts style home I would like windows with wood on the inside. I have been looking at Marvin aluminum clad wood windows and Mavin Infinity fiberglass with wood veneer inside. The aluminum clad are less expensive but I read one posting that said the argon dissipates much faster with this type window. Does anyone know if that is true?
