Moved to lower Michigan and have decide to build a basic 2 story "saltbox". The contractor I am considering tells me that it is standard here to build exterior walls with 2x4's. He will build with 2x6's if I so desire but at an xtra cost.
What are the advantages of a 2x6 wall over one built with 2x4's? Is it a structual/strength issue? An insulation issue? (The walls would be insulated to same necessary R value, correct? Same zone as my previous house)
What would be the main advantage of a 2x6 wall over 2x4?
Please clear this up for me?
