The best thing to use for covering your glass front door would be a curtain. Curtains are great because they can keep the cold air out during winter and help you save on energy costs, plus there’s more privacy than keeping it bare! Glass doors also let in a ton of natural light – but they can also let in unwanted draughts, sounds and diminish the amount of privacy that curtains provide. You don’t have to give up either when choosing between one or another: shades, drapes, and portieres that allow you to maintain both beauty and warmth without sacrificing any level of convenience or comfort are perfect for those wanting flair as well as functionality from their homes!
