Horizontal Insulation Stacking . . . . ?

[Delance412]

Does insulation still work if it is stacked horizontally as opposed to vertically? I have studs that vary in distance apart from 16” to 24” and everything in between. I ran the numbers and installing 2” thick foam boards with an R-10 rating would cost me around $450 plus another $50 in foam spray. Using R-13 Kraft Faced rolls would only cost me $120. The problem is the fixed width of the rolls. For one of the stud openings that is 25” wide, would I be able to cut the insulation to that width and stack it horizontally up the cavity? Would this work? I know it would be time consuming but I can spread the project out if I can save that much in materials. Thank you all in advance!!!!!

insulated thickness is insulated thickness. you fill the cavity for the purpose of trapping air and preventing air movement across (through) the cavity..

cutting pieces 25" long and stacking them like bricks up the cavity will work, but eventually they will fall down the cavity and stack on eachother at the bottom. make sure you staple each row at the studs to prevent it..

Stack it! Secure it you are good to go!
