You should ensure that the curtain is the correct width and height and that the correct number of panels are used. For curtains with eyelets you should allow at least 30% extra width, i.e. 130 cm for a 100 cm wide aisle. For curtains with our multi-functional tunnel tape, you can allow for slightly less material, as these curtains can be stretched more than the eyelet curtains hanging on a curtain rail. When choosing the height, remember that the curtain should rest on the floor to prevent cold air from creating an uncomfortable draught. For a passage or corridor, it is a good idea to use two curtain panels that you can walk through in the middle. This is much more convenient than using a single curtain that has to be constantly opened and closed. For a 100 cm wide hallway, this would mean two curtains with eyelets, each at least 65 cm wide (= 100 cm + 30% = 130 cm / 2 curtains = 65 cm per curtain).
