Due to them being constructed in a specific way, these types of curtains are not the best when it comes to fully blacking out your rooms, especially since the fibers can allow small lights to come through.
  • Polyester fabric – Great when it comes to making an extremely durable and absorbent type of blackout curtain, however, this fabric is not the best when it comes to fully blocking out your sunlight
