Hello,
I had posted this in alt.building.construction but I only got one responce...
I'm in the process of building a new house here in the Atlantic part of Canada. I'm looking at 3 way's of doing it:
First:
2x6(on 16" center) lumber, 7/16 Aspenite OSB with R-20x15 bat insulationSecond:
2x6(on 24" center) lumber, 7/16 Aspenite OSB with R-20x23 bat insulationThird:
2x4(on 16" center) lumber, 2" expanded polystyrene(R-8) with R-12x15 bat insulation and wind braceMost of the houses around here are done like the fist one. There are also a few contractors doing:
2x6(on 16" center) lumber, 1" 1/2 extruded polystyrene (R-7.5) with R-20x15 bat insulation.I'm king off looking at option 3 because it is the less expansive way and it seem to make more sense. It has the same R value of the fist one but you have extra "protection" on the studs (no thermal transfer, or less since you have a R-8 value covering it).
What are your points on this?
ThanksCh ristian
