Type X gypsum lath is distinguished by which property?

Explanation:
Type X gypsum lath is formulated to resist fire better than standard lath. Its gypsum core is reinforced with additives (such as glass fibers) that slow heat transfer and help plaster retain its integrity longer in a fire, giving the wall a higher fire-resistance rating. Because of this fire-retardant design, it’s specified for fire-rated plaster systems. The other properties listed—magnetism, weight, and moisture absorption—aren’t what distinguishes Type X lath.
