I have absolutely no idea if this is a trick question or something completely obvious that's just going over my head.
Why not do both? When they do the siding have the blown done just beforeThey can put as many hole in as they want and where they want and cover it as they goThe siding insulation isn't as good as the blown.If your house is drafty a major contribution could be around the windowsMake sure they frame your windows and Put the flashing around the windows the right way then the J channel for the sidingI have repaired homes with a lot of leaks around windows and doorsThe caulking that they count on so much now days isn't always done right and catches the run of water and makes it worseIt then traps it inside behind the siding slowly rotting the wood and form mildew and fungusIts not a pretty sight and very costly to repairSame goes for the metal work done on the frame of the windowscut the metal and bend it the right way it will never leakBut again they love to caulk everything now days because its fasterMake sure you check these things out before they finish their workGood Luck
I would go for the blown in insulation first of all, because it helps to stop any drafts, and there will be draftsAfter that I would still consider doing the insulated siding as well, you are going to have holes in the wood from blowing in insulation.
I live in Buffalo, NY where the winters are also brutalMy Cape Cod house was sided but my highest heating bills were still running $150 or higher4 years ago I hired a contractor to blow insulation into the wallsHe carefully removed pieces of siding, high and low areas, cut holes in the exterior, blew insulation in, then replaced the siding so there aren't any of those ugly plugsHis crew were very careful to get under and around all the windows and doorsHe couldn't do my upstairs this way so he did have to come inside and cut through the drywall in a few places to blow it in but they were easy to repairI haven't had a heating bill over $125 since and my house is nice and toasty.
Aluminium is in group 5 and needs 3 electrons to fill the outer shell and make it stableOxygen is in group 6 and needs 2 electrons to fill the outer shell and make it stableTo determine the chemical formula write the symbol of the chemicals in the compound i.eAl O Enter the numbers of which groups they belong toAl3 O2 Swap the numbers over So you end up with the chemical formula Al2O3 Thats the way i was taught to do it :)
There are allot of execs and cons on the use or non use of preformed foam panels used at the back of vinyl sidingI even have on no account seen the froth bonded to the lower back facet of the vinyl and there's a rationalization for thatVinyl expands and contracts with temperature alterations and foam does not, or a minimum of to not the comparable quantityit particularly is why the vinyl has horizontal nail slots and provision for growth and contraction on each end of the panelsbesides to that, there must be a fashion for moisture that condenses at the back of the vinyl to flee and evaporate into the ambiencein case you seem on the backside of each panel you will see a sprint weep hollowthat facilitates drainage of the condensationPreformed foam panels each from time to time block those holes and injury to the sheathing, extraordinarily if it particularly is OSB, would take placeI even have heard of a few lawsuits by using thisthe only actual benefit to it particularly is that it facilitates to conceal the overlapped seams and can furnish a company floor in case you push on itenormous deal! So who is going around pushing on your siding? I continuously used a million/2 Dow Board, (blue board) in 4' x 10' sheetsIt gave a greater ideal insulating high quality, allowed suitable air circulate at the back of the vinyl and smoothed out extraordinary siding surfacesIf the shopper insisted on a company backing, i'd cut back strips of foamboard that greater healthy at the back of the flat component to the vinyl(Dutch Lap) yet, that replaced into basically carried out on the get entry to way or the electrical powered meter sectionpurely submit to in techniques this maximum mandatory element: Vinyl is HUNG to a floor, not NAILEDleave the nail or screw heads some million/4 far off from the sheathing or foam.
