in my newly built 24x24 garage i have the walls insulated with osb board on the interior ...my ceiling is open.. but i have my lights mounted on my trusses. it has metal for the roof. how could i insulate the ceiling without closing in where my lights are which would be 8 foot from floor since i have 8 ft walls. how could i and what would i need to use to insulate up along the metal roof? thanks
