I recently put up some walls using steel studs. I bought full width
batts to cover the entire 16" gap between studs. The batts have no
paper vapor barrier. When I put the insulation in the wall, it
basically collapsed since there was nothing to secure the insulation in
an upright position. How should I secure the batts so they don't just
fall down? Is there some special tape I can use or some other
technique? I searched, but couldn't find anything for this specific
problem.
