hi i have a 40's home that is balloon framed now im adding full dormers the rafters on the house are the real 2x6's now was wondering if i should frame the new dormer roof with 2x6 or 2x8 studsthe house is 25 by 35 feet someone please help dont want to overkill nor cheap out. thanks
Your 2 concerns will be structure and insulation. The difference in the 2x6's, structure wise, is insignificant, old from new. Insulation wise, you can use a variety of products to optimize the value in a 2x6.
What did the architect spec out?
hi i didnt have an archictect but i work for a lumber yard and ask contractors alot of questrions andi get feedback on both sizes so i figured id go to a 3rd party. i am not concerned much about the insolation im concerned about structure. there's alot of new stuff out there for insolation.
