insulation and advanced framing
Zone 2, hot and humid---
I am thinking about building a 'shed', 16' x 24', 2 x4 walls, 24" OC, and want it to be energy efficient. (it might convert to an office space or MIL suite at some point in the future so I would want to get the details correct up front, plus i like learning about this stuff...)
So, I ~think~ from reading the tables, and please correct this idea if it is wrong, that I can frame the walls 24" OC and use 2 x 4s since it is single story with a simple roof.
If I pay the extra for 2 x 6 walls will the insulation gain(assuming i follow the techniques for a tight envelope) be worth it in my climate?
I would probably use a mini-split for hvac, or maybe a through the wall unit, if that matters.
Comments are appreciated!
Going to 2x6 for insulation purposes is not really worth it.
I prefer 2x6 structure but not for the insulation value.
Look up rigid foam to the exterior and go that route.
