How do insulate existing house following Hurricane Isaac
I have a couple of questions I hope can get answered here. Ive searched all day and not really found any answers.
I live in south Louisiana, very hot and very very humid. After this last hurricane I am going to be tasked with residing my house. No big deal, it needed it anyways.
The house is about 25 years old or so. It currently has sheetrock walls inside followed by regular insulation batts, plywood sheathing, black tar paper wrap, and finally vinyl siding.
I wanted to wrap the house in double bubble foil barriere was told by the company that it is not recommended because the reflected heat will damage my new vinyl.
What is recommended in a situation like this? Not interested in spray foam or the loose insulation. I was reading on the rigid foam boards but saw an article where it is mot recommended because of the batt insulation.
My question: if I go with foam boards and seal the tightly do they go on top of the black paper or should the black paper be removed? Should I rewrap the house with te perforated Tyvek and then foam board? What should I do and whay order does it need to be in? Im really concerned about moisture due to the humidity down here.
My house has all vented vinyl soffit all the way around, gable roof with ridge vent at the top. It sits on a slab about 4-6 from the ground.
