Is one better than the other? Will it help with insulation?
2x4 construction with styrofoam exterior gives you the insulation that you are required. The benifits are that the transfer of hot and cold on the plates and studs is reduced. This form of construction would surpase any convential 2x6 construction when calculating heat loss or gain. Not so when concerned with wind shear, the 2x6 structure is going to fair better.........14 percent of a 8 foot high wall is dimensional lumber with limited R-value.I'm shocked by this...c'mon...what stud size....does this affect insulation...2x4 vs. 2x6???????? Cardboard or plywood to sheet a roof, extension jamb a window.....here it's 21/42 .....even in dryer/hotter areas benefit from better insulation.
2x4 walls are unheard of for ext. walls, in this area at least. Geeeeeze.......I'm dumbfounded.
Don't be two dumbfounded because 2x4's are used every day for exterior walls around here.2x4 walls are unheard of for ext. walls, in this area at least. Geeeeeze.......I'm dumbfounded.
Of course you can. You can build threes stories, at least here in Jersey. Foundation are built the same for 1-2 and 3 story homes and 2x4's can hold them with no problems.House I just bought has all 2x4 ext. walls on it. Although its a 1 story ranch house. My question though away from the insulation, (my house isnt insulated) is can you build an additional story on 2x4 walls?
In New Jersey they are.Not all foundations are built the same to hold one or two story homes
Because heat rises, most of your loss/gain is through your ceiling/roof. Because much of your exterior walls are windows and doors, much of your wall space is unaffected by the r-19 vs r-13 difference.
Sure, the r-19 saves some pennies, but why not look first at the dollars?
