Question:

thinking about using blown-in insulation.?

in my mobile home exterior wallsNow my first question is, is this a legitimate way to improve our winter utility bills? Secondly, since there is no way to blow the insulation down from above (no attic), I guess I would have to drill a hole at the top of each section (between the studs) to blow it inso with that said, would I go ahead and leave the pre-existing rolled insulation inside the wall and blow the new in, or would I need to take each wall panel off and pull the insulation out before blowing new insulation inside the walls?tl:dr1.is blow in insulation a good way to improve heating bills/can it be used in mobile home walls?2.can i use blow in insulation without removing the existing rolled insulation?

i need help with that too
drill and fill is a viable way to increase insulation and lower bills even if there is existing insulation in thereHow much of a improvement you get depends on how old the insulation is and how well it was installedIf you do drill and fill it will at minimum need to be a high density cellulose fill(no fiberglass) OR a a foam fill like retrofoamGet the higher quality stuff in your ceiling if you can afford it(with high density fills you don't have to worry about removing what is in there.) Instead of window replacements look at getting window inserts or insulated curtains that seal against the sides of your windows with magnet strips or velcro(window inserts are like plexiglas that has sealing baffles on the edges) Both of these options have downsides to real window replacements but the payback on them is much quicker as the install costs are much lowerAlso, it is important for a mobile home is to insulate and air seal the skirt and make sure no air can blow underneath your home Most important on any home is to do air sealingMake sure all the windows, gaps and cracks are all caulked upMake sure that your door gasketing is well aligned and seals the door well when it closes Also of note, contact your states weatherization programYou might even qualify for them to come and do this work for free or at a reduced cost depending on your income level, family size etcAt the very least they can give you some good advice specific to your area.
