I was thinking we could benefit from a thread to discuss house efficiency and related household maintenance, construction ......
IDK, I'm just brainstorming here a bit. I see a few members from time to time who are newer to home ownership. Maybe this should be a separate forum filled with vast information?
I'll start. I've never been found of much of the new construction practices found in modern homes. I love the 2x6 exterior walls allowing an insulation value of R19. I have a huge dismay for OSB sheathing. Doesn't take long for moisture to destroy it. For example if there is a leak in the siding, that goes undetected, it doesn't take long for the glues to soften and the strands to rot. With plywood or ship lap sheathing it can sustain a significant amount of abuse before giving way.
On the older homes with 1 3/4 x 3 3/4 wall studs there is more space available than the R13 they get filled with. To help make these walls tighter one can use 1/2'' foil faced foam board, to add another 3.5 R value, directly fastned to the interior of the external sheathing. Run a thin bead of caulk where the board meets the studs to close any air gaps. Be sure to install a vapor barrier on the interior of the wall studs to keep moisture out of the walls or, make perforations in the foam board.
Speaking of moisture barriers, I've always had a question that doesn't sit well with me in even more modern construction. Does the "Zip" system of vinyl coated OSB and its taped seams not trap moisture in the walls?
I hope to see this thread take off so we can share a wealth of knowledge, and DIYers can all have another place to learn from. I learn stuff on a daily basis. Happily too.
