With this block-out blind you won’t have your sleep disturbed by moonlight and street lights - or be woken by the sun when you want to sleep in late. 38x76 ¾ ". May help you reduce heating costs as the air inside the honeycomb structure creates a layer of insulation. Can be mounted on the wall or ceiling. No need to change fittings or drill new holes if you change your blinds. The included wall/ceiling brackets are suitable for HOPPVALS and TRIPPEVALS cellular blinds and SKOGSKLÖVER roller blind.
