1. A strip of curtains: this type of curtain usually consists of several individual vertical panels that can be pushed open or closed manually or automatically. Their main advantage is flexibility and controllability. It is possible to pull back only some of the curtain sheets as needed, or to push them open completely for more access space. It is also easier to replace damaged curtains as each curtain is independent. However, a strip of curtains may require more maintenance to ensure a tight connection between each curtain piece and to prevent fumes from entering other areas through gaps.
2. Positive Piece Curtains: This type of curtain is a continuous curtain made from a single piece of fabric. They are usually made of grease and smoke resistant materials that effectively isolate grease and smoke. Compared to a strip of curtains, positive sheeted curtains are simpler to install and maintain because there are no individual sheets that need to be attached or replaced. Additionally, a positively sheeted curtain also provides better screening, making it impossible for grease and smoke to penetrate through the curtain to other areas. However, because it's one continuous piece of curtain fabric, a front-paneled curtain may limit flexibility in getting in and out of the space.
In summary, if you're more interested in flexibility and controllability, as well as ease of maintenance and replacement, then a one-piece curtain may be better for you. If you're more focused on grease and smoke resistance and simple installation, then a positive slat curtain may be better for you. The final choice should be based on your individual needs.
