<p>An insulating paperboard (12) is formed from at least one layer (14) of cellulose fibers. The one layer (14) is at least partially formed from bulky fibers. The paperboard is sufficiently insulated to provide a hot water ΔT across the paperboard of at least 0.7°C ± 2.3°C per 0.1 mm caliper. The paperboard may be embossed to decrease surface transmission of heat. A hot cup may be produced from the insulating paperboard.
