Reply to comment by Tito_Mojito in diy blown in insulation question for first timer. 100+ year old home. by jjax2003

there is perpendicular boards in the attic and suck which woul make laying another layer on top not sit flat with the existing layer leaving an air gas between both layers of insulation. i thought that was bad.
