First off please do not respond with redneck, trailer trash, or similar comments about my home, it's a very nice house and I'm very proud of itOk now the question! Our house has the vinyl underpinning (saving up for a nicer foundation, but that will come in time), it's 28ft w and 60ft long, and it sits pretty much on a hillThis causes a lot of cross winds to come through the vinyl, what would be the best way to insulate the area under the house to prevent air leaks? Would it be better to do the spray in insulation, going underneath and literally spraying the whole place down or going the packaged route and stuffing the place full of fiberglass insulation? Spray insulation I worry would be blown out by the wind (I seriously know VERY little about this, so I'm sorry if that comes off like the dumbest sentence you've ever read.) If I choose to physically lay out the packaged insulation under the home would I need to secure it with any special tools or specialized hangers?
for two, a good hour and halfknow your neighbor? ask if you use their oveni have had to do that beforeyou might want to grill chickenask for help! have a great party!
I suggest noting the difference between skirting, the panels that keep stuff, and a lot of air, from just blowing under the 'home, vsthe actual insulation underneath the floorNot worth the trouble to try to get air-tight skirting (and could actually cause mold problems due to a lack of ventilation), but definitely good to max under the floorTreat it just like insulating a crawl space under a regular house, thick and then sheeted over with plastic, for a vapor barrierAs long as you're down there, also get to know where your water supply line and drain line is, etc., especially if you've had any trouble in this cold winter.
