what is the best way to insulate the house in between studs and what is the best insulation out there for this purpose?
roof insulation and doubbel glazing
This mainly depends on wether the walls are open to the studs or notAlso, are you going to be doing the work or hiring the job out?Lets take the most straight forward scenario of open walls and you doing the workYou need to determine the depth of your studs(2x4,2x6), and the spacing between themDetermine the square footage you need to coverThen go to the home center, find the right width of battsand determine the R-value that will fit( they can assist with this)Look for batts with a vapor barrior for exterior walls and unfaced for interior wallsPurchace enough to cover the square footage you need plus 1 bundle for major errorsThen install as per instructions on packageAs to what type is best, there has been much debate with little concrete solutionsI recommend that you purchace what is most fitting for your situation, and try to get the highest R-value you can that will fit within your specific perameters(price, cavity size, etc.)It matters little which type you choose as long as you improve the insulation factor within the home and can do it within your bugetary constraintsHope this was of some help.
