Fiberglass.cheaper, better insulator, and less fire hazard.
OK so here is what I know: Styrofoam-I do not recommend using for an entire home, I would use it for a garage, because it doesn't really insulate that wellFiberglass: Is cost effective and is a really good insulationAlso it's stock, in the stores so it's also readily availableJean insulation: It's make of recycled jeans, and it's pretty good if you are environmentally conscience Spray foam: This is also recycled material in most cases and is reasonably priced, but you can't do this on your own you have to call in a special installer for thisI would go with fiberglass, cause it's cost effective, found everywhere, and you can do it yourself! Hope that helps!
This depends on where you are using itYou want to use foam panels in the basement, garage, and other places that may get wetFoam will dry out betterFiberglass with a vapor barrier is good for walls and ceilings to fill in between joistsFiber glass works best in areas where it will not be compressedWhen you stuff fiberglass insulation into a place, it loses a lot of it's r-valueSpray foam (comes in a can) is good for cracks and crevices around pipes, doors, windows, etcIt can be messy thoughThe blow in cellulose insulation is okay for attics and is cheap (and most home improvement stores rent/loan you a blower for free when you buy a certain amount of insulation from them) but it will take two people to run (one to feed the hopper and one to blow the stuff in), and it settles 20 to 25% so you have to use moreSettling will reduce it r-value, like stuffing in fiberglassI forgot to mention that Fiberglass insulation will settle as well, but only around 10%Foam panels or spray in does not settle, so it won't lose any of it's r-value.
Line a pan with aluminum foilIt can be scrap aluminum, as long as it is cleanPlace your silver on the aluminumBoil water, dissolve a teaspoon of salt and a cup of baking soda into itPour into the pan, covering your silverThe tarnish, caused by sulfur attaching itself to the silver, is transferred to the aluminum via the 'salt bridge', resulting in nice clean silver once again without the hassle of having to polish it.
