A balcony barrier is a structure that is used to provide safety and security for those on a balcony. The most common solutions for this are a PARAPET, which is a low wall or railing, a LOGE, which is a small balcony with a railing, a genet, which is a type of railing made of metal, and an EMOTE, which is a type of decorative railing. All of these solutions can be used to create a safe and secure balcony barrier.
