Insulating Floors Above Unheated Garages in Scotch Plains, NJ
When insulating floors above unconditioned garages, first seal all possible sources of air leakage. This strategy has the added benefit of minimizing the danger of contaminants (from car exhaust, paint, solvents, gardening supplies, etc.) in the garage migrating into the conditioned space. Also install an air barrier to prevent cold air in the garage from “short circuiting” the insulation underneath the sub-floor of your Scotch Plains, NJ home.
