The H.VERSAILTEX Blackout Curtain is a solid choice if you want to block out sunlight and improve privacy on your sliding glass door. Made from durable textured polyester with a 100% blackout lining, it effectively blocks all bright light and UV rays, which can help protect your furniture and create a dark room for better sleep. The curtain measures a generous 100 inches wide by 96 inches long, which suits most standard sliding doors and is designed with 16 rust-resistant grommets for easy hanging on rods up to 1.5 inches thick.

Maintenance is simple since the curtain is machine washable, but you should use cold water and avoid chlorine bleach to keep it in good shape.

A couple of things to note: while it offers excellent light blocking, the curtain is quite thick, so it might feel a bit heavy or less airy if you prefer lighter fabrics.
