Insulation, Radiant and Vapor Barriers - Insulation between odd sized studs...

Thanks in advance for any advice offered...
Using Batting (spelling?) in a basment between studs - 24" OC. I have several places where the studs are odd sized - one space it's about 12" between studs, another is 8", one is about 20", so on and so on. I have a lot of batting left over for 24" studs. What's the best way to insulate those odd sized ones?

You will need to use a long straightedge as a guide for a sharp utility knife,

measure the space between the studs and slit the roll or batt of insul. to

that width. You will need to add a little extra so you have some paper face

to staple on the cut edge and I usually add a little more for ''good measure''.

The insul. itself will be just a little wider than you need after cutting, I just

''fudge'' it in between the studs, with the rest of it. A little extra won't hurt.

When you cut the insul., you will need a good sharp blade in the knife, lay

the insul. face up on a wood surface that you don't mind scarring up and

push down on the insul. to compress it as you cut. You may find a place to

use some of the ''scrap'' thats generated, if not at first, save it till the job

is all done, you may need small pieces to shove into nooks and crannies.
