Front curtain

A front curtain, also known as a house curtain, act curtain, grand drape, main drape or main rag, is the stage curtain or curtains at the very front of a theatrical stage.

Typically, the front curtain is opened at the beginning of a performance to reveal the stage set and closed during intermissions and at the end of a performance. The most common material for the front curtain is a heavy velour material, often with pleated fullness sewn into the fabric to create a more opulent appearance.
