I am remodeling my living room and pulled down a ceiling that exposed an old porch roof made from 2X4's on 22 inch centersThere was R30 insulation on top of the ceiling that I pulled down and I want to leave the vaulted ceiling and cover it with 1X8 TGI know I need to put insulation between the roof joists but I don't think I can get the same R30 (needs at least 9-10 inches?) in the 2X4 space.What is my best options to get the maximum R value in my ceiling?
Paper is inert in a microwave ovenIt's like running the microwave empty (which isn't good for the oven)I frequently use paper towels in my microwave cooking to absorb grease and control spattering.
Sparking first , then burn the plastic inside, and then blow the microwave fuse insideAfter that happen, your microwave oven lost about 40% of its cooking power due to overloaded its magnetron.
What you're describing is a heck of a structural deficiencyI don't know if you live somewhere with a snow load or not (hopefully not) but with 2x4's on 22 inch centers, the weight of the roofing material plus the weight of the pine you're putting up will result in the roof being unstableNot to mention a code violationAs the last guy said there's also a venting problem even if you did stuff R-13 up there and button it upEvery roof system needs proper ventilation or whatever kind of roofing material you have is going to fail very quicklyPlus you could have a problem with mold, excess heat load inside, etcIn a properly constructed vault roof there are styrofoam panels which hold the insulation away from the underside of the roof sheathing but you certainly don't have room for thatI would seriously consider re-framing the roof system.
