Exterior wall thickness???

diverdaveman

I’m remodeling a house and had to remove the walls on the back porch which is considered part of the heated square foot since there is an air vent in the floor. Should the new walls be 2x4 or 2x6 – or does it matter?

Thanks,
Dave

what do the codes for your area say

Not sure what geographical area you are in, but in my opinion bigger is better. The 2x6 framing would allow for better/thicker insulation and will stand up to the elements better, i.e high winds. then you are covered either way, if code says 2x4 minimum then you are one step above, and if code says 2x6 minimum then you are still compliant.

Remember with 2x6 framing, you'll have recessed windows.

I would build with what size you took out.

I would frame it out with 2x6's if you have the room. Additions have more walls exposed to the elements then the other rooms. Usually three sides, the ceiling and the floor are connected to unheated spaces. Heat loss is greater and quicker. I always frame additions with 2x6's and separately zone them.

Thanks for all the info. I'll check my local building codes to see what "they" want.
