Block-out curtains blocks light from shining through and completely darkens your room.
Effective at keeping out both draughts in the winter and heat in the summer.
Curtains with heading tape allow you to hang the curtain directly on the curtain rod using the rod pocket or tabs. You can also hinge the curtain onto a track rail using gliders and hooks.
Using gliders and hooks usually creates a more formal and dressed-up feel, where hardware is not visible.
