December 31, 20214 yr Hi laying my floor insulation and was wonder how much stagger I need in the joints for the second layer. finding it hard going down hall and into rooms to get a good stagger on them and can not find guidance on what the minimum is. thanks
December 31, 20214 yr Hi, you should aim for as large an overlap as as possible, but as long as the joint don't coincide with each other you should fine with a small overlap. The main reason for the staggered joints is to limit the thermal bridge, if you have gaps at joints.
