• Only DeGeorge suspended ceiling panels (2′ x 4′) that are at least 5/8″ thick can be back-loaded with additional insulation. Rolled insulation must be used and installed perpendicular to the cross tees so that the weight of the insulation rests on the suspended grid system, and there is air space between the insulation and the panel. Ask your dealer for specific details. Note: Insulation must never be placed behind fire-rated ceilings, unless designated in a UL design assembly. Backloading fiberglass panels is not recommended.
