100% opaque: The Joydeco opaque curtains are two-layer and have a back lining. The innovative two-layer fabric blocks 100% sunlight and harmful UV rays (dark colours provide a better effect) to ensure that the room temperature stays pleasantly cool in summer and keeps the heat inside in winter. Easy installation: 1. Rod pull: the curtains have no curtain rings or hooks, which keeps the appearance clean and tidy. Easy to push. 2. Loops: This improves the decoration effect and gives the curtains more style and uniqueness. The curtain rings or hooks provide better support and stability, making the curtains more durable. Suitable for use with rods or rail systems. Packaging specifications: each packaging contains opaque curtain panels. The dimensions of each panel are (140B175H/117B137H/140B245H/140B220H/106B158H/135B240H/132B210H/132B158H/167B228H/140B200H/140B260. etc. [Material] Our faux linen fabric is a great alternative to real linen.
