what is your recommendation? Wood clad or vinyl? and the brands for replacement windows? I browsed tje reviews and I am not too sure about the brands or the type.
Wood clad vs. vinyl are typically decisions of aesthetics and material choice requirements. Those two are not in the running when you are considering energy efficiency or price for that matter.
The money that you will spend on a wood clad vinyl, you could get the best vinyl window installed and be light years ahead on energy efficiency and durability.
